36 System Storage Manager provides an easy to use command line interface
37 to manage your storage using various technologies like lvm, btrfs,
38 encrypted volumes and more.
39 In more sophisticated enterprise storage environments, management with
41 Device Mapper (dm), Logical Volume Manager (LVM), or Multiple Devices
42 (md) is becoming increasingly more difficult. With file systems added
43 to the mix, the number of tools needed to configure and manage storage
44 has grown so large that it is simply not user friendly. With so many
45 options for a system administrator to consider, the opportunity for
46 errors and problems is large.
47 The btrfs administration tools have shown us that storage management
49 can be simplified, and we are working to bring that ease of use to
50 Linux filesystems in general.

77 option ssm will not perform all the check as some of them are
78 done by the backends themselves. This option is mainly used for
79 debugging purposes, but still requires root privileges.

82 Introduction
83 System Storage Manager has several commands that you can specify on the
84 command line as a first argument to ssm. They all have a specific use
85 and their own arguments, but global ssm arguments are propagated to all
86 commands.
87 Create command
89 ssm create [-h] [-s SIZE] [-n NAME] [--fstype FSTYPE] [-r LEVEL] [-I
90 STRIPESIZE] [-i STRIPES] [-p POOL] [-e [{luks,plain}]] [-o MNT_OPTIONS]
91 [-v VIRTUAL_SIZE] [device [device ...]] [mount]
92 This command creates a new volume with defined parameters. If a device
94 is provided it will be used to create the volume, hence it will be
95 added into the pool prior to volume creation (See Add command section).
96 More than one device can be used to create a volume.
97 If the device is already being used in a different pool, then ssm will
99 ask you whether you want to remove it from the original pool. If you
100 decline, or the removal fails, then the volume creation fails if the
101 SIZE was not provided. On the other hand, if the SIZE is provided and
102 some devices can not be added to the pool, the volume creation might
103 still succeed if there is enough space in the pool.
104 In addition to specifying size of the volume directly, percentage can
106 be specified as well. Specify --size 70% to indicate the volume size to
107 be 70% of total pool size. Additionally, percentage of the used, or
108 free pool space can be specified as well using keywords FREE, or USED
109 respectively.
110 The POOL name can be specified as well. If the pool exists, a new vol‐
112 ume will be created from that pool (optionally adding device into the
113 pool). However if the POOL does not exist, then ssm will attempt to
114 create a new pool with the provided device, and then create a new vol‐
115 ume from this pool. If the --backend argument is omitted, the default
116 ssm backend will be used. The default backend is lvm.
117 ssm also supports creating a RAID configuration, however some back-ends
119 might not support all RAID levels, or may not even support RAID at all.
120 In this case, volume creation will fail.
121 If a mount point is provided, ssm will attempt to mount the volume
123 after it is created. However it will fail if mountable file system is
124 not present on the volume.
125 If the backend allows it (currently only supported with lvm backend),
127 ssm can be used to create thinly provisioned volumes by specifying
128 --virtual-size option. This will automatically create a thin pool of a
129 given size provided with --size option and thin volume of a given size
130 provided with --virtual-size option and name provided with --name
131 option. Virtual size can be much bigger than available space in the
132 pool.
133 -h, --help
135 show this help message and exit
136 -s SIZE, --size SIZE
138 Gives the size to allocate for the new logical volume. A size
139 suffix K|k, M|m, G|g, T|t, P|p, E|e can be used to define 'power
140 of two' units. If no unit is provided, it defaults to kilobytes.
141 This is optional and if not given, maximum possible size will be
142 used. Additionally the new size can be specified as a percent‐
143 age of the total pool size (50%), as a percentage of free pool
144 space (50%FREE), or as a percentage of used pool space
145 (50%USED).
146 -n NAME, --name NAME
148 The name for the new logical volume. This is optional and if
149 omitted, name will be generated by the corresponding backend.
150 --fstype FSTYPE
152 Gives the file system type to create on the new logical volume.
153 Supported file systems are (ext3, ext4, xfs, btrfs). This is
154 optional and if not given file system will not be created.
155 -r LEVEL, --raid LEVEL
157 Specify a RAID level you want to use when creating a new volume.
158 Note that some backends might not implement all supported RAID
159 levels. This is optional and if no specified, linear volume will
160 be created. You can choose from the following list of supported
161 levels (0,1,10).
162 -I STRIPESIZE, --stripesize STRIPESIZE
164 Gives the number of kilobytes for the granularity of stripes.
165 This is optional and if not given, backend default will be used.
166 Note that you have to specify RAID level as well.
167 -i STRIPES, --stripes STRIPES
169 Gives the number of stripes. This is equal to the number of
170 physical volumes to scatter the logical volume. This is optional
171 and if stripesize is set and multiple devices are provided
172 stripes is determined automatically from the number of devices.
173 Note that you have to specify RAID level as well.
174 -p POOL, --pool POOL
176 Pool to use to create the new volume.
177 -e [{luks,plain}], --encrypt [{luks,plain}]
179 Create encrpted volume. Extension to use can be specified.
180 -o MNT_OPTIONS, --mnt-options MNT_OPTIONS
182 Mount options are specified with a -o flag followed by a comma
183 separated string of options. This option is equivalent to the -o
184 mount(8) option.
185 -v VIRTUAL_SIZE, --virtual-size VIRTUAL_SIZE
187 Gives the virtual size for the new thinly provisioned volume. A
188 size suffix K|k, M|m, G|g, T|t, P|p, E|e can be used to define
189 'power of two' units. If no unit is provided, it defaults to
190 kilobytes.
191 Info command
193 ssm info [-h] [item]
194 EXPERIMENTAL This feature is currently experimental. The output format
196 can change and fields can be added or removed.
197 Show detailed information about all detected devices, pools, volumes
199 and snapshots found on the system. The info command can be used either
200 alone to show all available items, or you can specify a device, pool,
201 or any other identifier to see information about the specific item.
202 -h, --help
204 show this help message and exit
205 List command
207 ssm list [-h] [{volumes,vol,dev,devices,pool,pools,fs,filesys‐
208 tems,snap,snapshots}]
209 Lists information about all detected devices, pools, volumes and snap‐
211 shots found on the system. The list command can be used either alone to
212 list all of the information, or you can request specific sections only.
213 The following sections can be specified:
215 {volumes | vol}
217 List information about all volumes found in the system.
218 {devices | dev}
220 List information about all devices found on the system. Some
221 devices are intentionally hidden, like for example cdrom or
222 DM/MD devices since those are actually listed as volumes.
223 {pools | pool}
225 List information about all pools found in the system.
226 {filesystems | fs}
228 List information about all volumes containing filesystems found
229 in the system.
230 {snapshots | snap}
232 List information about all snapshots found in the system. Note
233 that some back-ends do not support snapshotting and some cannot
234 distinguish snapshot from regular volumes. In this case, ssm
235 will try to recognize the volume name in order to identify a
236 snapshot, but if the ssm regular expression does not match the
237 snapshot pattern, the problematic snapshot will not be recog‐
238 nized.
239 -h, --help
241 show this help message and exit
242 Remove command
244 ssm remove [-h] [-a] [items [items ...]]
245 This command removes an item from the system. Multiple items can be
247 specified. If the item cannot be removed for some reason, it will be
248 skipped.
249 An item can be any of the following:
251 device Remove a device from the pool. Note that this cannot be done in
253 some cases where the device is being used by the pool. You can
254 use the -f argument to force removal. If the device does not
255 belong to any pool, it will be skipped.
256 pool Remove a pool from the system. This will also remove all volumes
258 created from that pool.
259 volume Remove a volume from the system. Note that this will fail if the
261 volume is mounted and cannot be forced with -f.
262 -h, --help
264 show this help message and exit
265 -a, --all
267 Remove all pools in the system.
268 Resize command
270 ssm resize [-h] [-s SIZE] volume [device [device ...]]
271 Change size of the volume and file system. If there is no file system,
273 only the volume itself will be resized. You can specify a device to add
274 into the volume pool prior the resize. Note that the device will only
275 be added into the pool if the volume size is going to grow.
276 If the device is already used in a different pool, then ssm will ask
278 you whether or not you want to remove it from the original pool.
279 In some cases, the file system has to be mounted in order to resize.
281 This will be handled by ssm automatically by mounting the volume tempo‐
282 rarily.
283 In addition to specifying new size of the volume directly, percentage
285 can be specified as well. Specify --size 70% to resize the volume to
286 70% of it's original size. Additionally, percentage of the used, or
287 free pool space can be specified as well using keywords FREE, or USED
288 respectively.
289 Note that resizing btrfs subvolume is not supported, only the whole
291 file system can be resized.
292 -h, --help
294 show this help message and exit
295 -s SIZE, --size SIZE
297 New size of the volume. With the + or - sign the value is added
298 to or subtracted from the actual size of the volume and without
299 it, the value will be set as the new volume size. A size suffix
300 of [k|K] for kilobytes, [m|M] for megabytes, [g|G] for giga‐
301 bytes, [t|T] for terabytes or [p|P] for petabytes is optional.
302 If no unit is provided the default is kilobytes. Additionally
303 the new size can be specified as a percentage of the original
304 volume size ([+][-]50%), as a percentage of free pool space
305 ([+][-]50%FREE), or as a percentage of used pool space
306 ([+][-]50%USED).
307 Check command
309 ssm check [-h] device [device ...]
310 Check the file system consistency on the volume. You can specify multi‐
312 ple volumes to check. If there is no file system on the volume, this
313 volume will be skipped.
314 In some cases the file system has to be mounted in order to check the
316 file system. This will be handled by ssm automatically by mounting the
317 volume temporarily.
318 -h, --help
320 show this help message and exit
321 Snapshot command
323 ssm snapshot [-h] [-s SIZE] [-d DEST | -n NAME] volume
324 Take a snapshot of an existing volume. This operation will fail if the
326 back-end to which the volume belongs to does not support snapshotting.
327 Note that you cannot specify both NAME and DEST since those options are
328 mutually exclusive.
329 In addition to specifying new size of the volume directly, percentage
331 can be specified as well. Specify --size 70% to indicate the new snap‐
332 shot size to be 70% of the origin volume size. Additionally, percentage
333 of the used, or free pool space can be specified as well using keywords
334 FREE, or USED respectively.
335 In some cases the file system has to be mounted in order to take a
337 snapshot of the volume. This will be handled by ssm automatically by
338 mounting the volume temporarily.
339 -h, --help
341 show this help message and exit
342 -s SIZE, --size SIZE
344 Gives the size to allocate for the new snapshot volume. A size
345 suffix K|k, M|m, G|g, T|t, P|p, E|e can be used to define 'power
346 of two' units. If no unit is provided, it defaults to kilobytes.
347 This is optional and if not given, the size will be determined
348 automatically. Additionally the new size can be specified as a
349 percentage of the original volume size (50%), as a percentage of
350 free pool space (50%FREE), or as a percentage of used pool space
351 (50%USED).
352 -d DEST, --dest DEST
354 Destination of the snapshot specified with absolute path to be
355 used for the new snapshot. This is optional and if not specified
356 default backend policy will be performed.
357 -n NAME, --name NAME
359 Name of the new snapshot. This is optional and if not specified
360 default backend policy will be performed.
361 Add command
363 ssm add [-h] [-p POOL] device [device ...]
364 This command adds a device into the pool. By default, the device will
366 not be added if it's already a part of a different pool, but the user
367 will be asked whether or not to remove the device from its pool. When
368 multiple devices are provided, all of them are added into the pool. If
369 one of the devices cannot be added into the pool for any reason, the
370 add command will fail. If no pool is specified, the default pool will
371 be chosen. In the case of a non existing pool, it will be created using
372 the provided devices.
373 -h, --help
375 show this help message and exit
376 -p POOL, --pool POOL
378 Pool to add device into. If not specified the default pool is
379 used.
380 Mount command
382 ssm mount [-h] [-o OPTIONS] volume directory
383 This command will mount the volume at the specified directory. The vol‐
385 ume can be specified in the same way as with mount(8), however in addi‐
386 tion, one can also specify a volume in the format as it appears in the
387 ssm list table.
388 For example, instead of finding out what the device and subvolume id of
390 the btrfs subvolume "btrfs_pool:vol001" is in order to mount it, one
391 can simply call ssm mount btrfs_pool:vol001 /mnt/test.
392 One can also specify OPTIONS in the same way as with mount(8).
394 -h, --help
396 show this help message and exit
397 -o OPTIONS, --options OPTIONS
399 Options are specified with a -o flag followed by a comma sepa‐
400 rated string of options. This option is equivalent to the same
401 mount(8) option.
402 Migrate command
404 ssm migrate [-h] source target
405 Move data from one device to another. For btrfs and lvm their special‐
407 ized utilities are used, so the data are moved in an all-or-nothing
408 fashion and no other operation is needed to add/remove the devices or
409 rebalance the pool. Devices that do not belong to a backend that sup‐
410 ports specialized device migration tools will be migrated using dd.
411 This operation is not intended to be used for duplication, because the
413 process can change metadata and an access to the data may be difficult.

419 Introduction
420 Ssm aims to create a unified user interface for various technologies
421 like Device Mapper (dm), Btrfs file system, Multiple Devices (md) and
422 possibly more. In order to do so we have a core abstraction layer in
423 ssmlib/main.py. This abstraction layer should ideally know nothing
424 about the underlying technology, but rather comply with device, pool
425 and volume abstractions.
426 Various backends can be registered in ssmlib/main.py in order to handle
428 specific storage technology, implementing methods like create, snap‐
429 shot, or remove volumes and pools. The core will then call these meth‐
430 ods to manage the storage without needing to know what lies underneath
431 it. There are already several backends registered in ssm.
432 Btrfs backend
434 Btrfs is the file system with many advanced features including volume
435 management. This is the reason why btrfs is handled differently than
436 other conventional file systems in ssm. It is used as a volume manage‐
437 ment back-end.
438 Pools, volumes and snapshots can be created with btrfs backend and here
440 is what it means from the btrfs point of view:
441 pool A pool is actually a btrfs file system itself, because it can be
443 extended by adding more devices, or shrunk by removing devices
444 from it. Subvolumes and snapshots can also be created. When the
445 new btrfs pool should be created, ssm simply creates a btrfs
446 file system, which means that every new btrfs pool has one vol‐
447 ume of the same name as the pool itself which can not be removed
448 without removing the entire pool. The default btrfs pool name is
449 btrfs_pool.
450 When creating a new btrfs pool, the name of the pool is used as
452 the file system label. If there is an already existing btrfs
453 file system in the system without a label, a btrfs pool name
454 will be generated for internal use in the following format
455 "btrfs_{device base name}".
456 A btrfs pool is created when the create or add command is used
458 with specified devices and non existing pool name.
459 volume A volume in the btrfs back-end is actually just btrfs subvolume
461 with the exception of the first volume created on btrfs pool
462 creation, which is the file system itself. Subvolumes can only
463 be created on the btrfs file system when it is mounted, but the
464 user does not have to worry about that since ssm will automati‐
465 cally mount the file system temporarily in order to create a new
466 subvolume.
467 The volume name is used as subvolume path in the btrfs file sys‐
469 tem and every object in this path must exist in order to create
470 a volume. The volume name for internal tracking and that is vis‐
471 ible to the user is generated in the format "{pool_name}:{volume
472 name}", but volumes can be also referenced by its mount point.
473 The btrfs volumes are only shown in the list output, when the
475 file system is mounted, with the exception of the main btrfs
476 volume - the file system itself.
477 Also note that btrfs volumes and subvolumes cannot be resized.
479 This is mainly limitation of the btrfs tools which currently do
480 not work reliably.
481 A new btrfs volume can be created with the create command.
483 snapshot
485 The btrfs file system supports subvolume snapshotting, so you
486 can take a snapshot of any btrfs volume in the system with ssm.
487 However btrfs does not distinguish between subvolumes and snap‐
488 shots, because a snapshot is actually just a subvolume with some
489 blocks shared with a different subvolume. This means, that ssm
490 is not able to directly recognize a btrfs snapshot. Instead,
491 ssm will try to recognize a special name format of the btrfs
492 volume that denotes it is a snapshot. However, if the NAME is
493 specified when creating snapshot which does not match the spe‐
494 cial pattern, snapshot will not be recognized by the ssm and it
495 will be listed as regular btrfs volume.
496 A new btrfs snapshot can be created with the snapshot command.
498 device Btrfs does not require a special device to be created on.
500 Lvm backend
502 Pools, volumes and snapshots can be created with lvm, which pretty much
503 match the lvm abstraction.
504 pool An lvm pool is just a volume group in lvm language. It means
506 that it is grouping devices and new logical volumes can be cre‐
507 ated out of the lvm pool. The default lvm pool name is
508 lvm_pool.
509 An lvm pool is created when the create or add commands are used
511 with specified devices and a non existing pool name.
512 Alternatively a thin pool can be created as a result of using
514 --virtual-size option to create thin volume.
515 volume An lvm volume is just a logical volume in lvm language. An lvm
517 volume can be created with the create command.
518 snapshot
520 Lvm volumes can be snapshotted as well. When a snapshot is cre‐
521 ated from the lvm volume, a new snapshot volume is created,
522 which can be handled as any other lvm volume. Unlike btrfs lvm
523 is able to distinguish snapshot from regular volume, so there is
524 no need for a snapshot name to match special pattern.
525 device Lvm requires a physical device to be created on the device, but
527 with ssm this is transparent for the user.
528 Crypt backend
530 The crypt backend in ssm uses cryptsetup and dm-crypt target to manage
531 encrypted volumes. The crypt backend can be used as a regular backend
532 for creating encrypted volumes on top of regular block devices, or even
533 other volumes (lvm or md volumes for example). Or it can be used to
534 create encrypted lvm volumes right away in a single step.
535 Only volumes can be created with crypt backend. This backend does not
537 support pooling and does not require special devices.
538 pool The crypt backend does not support pooling, and it is not possi‐
540 ble to create crypt pool or add a device into a pool.
541 volume A volume in the crypt backend is the volume created by dm-crypt
543 which represents the data on the original encrypted device in
544 unencrypted form. The crypt backend does not support pooling,
545 so only one device can be used to create crypt volume. It also
546 does not support raid or any device concatenation.
547 Currently two modes, or extensions are supported: luks and
549 plain. Luks is used by default. For more information about the
550 extensions, please see cryptsetup manual page.
551 snapshot
553 The crypt backend does not support snapshotting, however if the
554 encrypted volume is created on top of an lvm volume, the lvm
555 volume itself can be snapshotted. The snapshot can be then
556 opened by using cryptsetup. It is possible that this might
557 change in the future so that ssm will be able to activate the
558 volume directly without the extra step.
559 device The crypt backend does not require a special device to be cre‐
561 ated on.
562 MD backend
564 MD backend in ssm is currently limited to only gather the information
565 about MD volumes in the system. You can not create or manage MD volumes
566 or pools, but this functionality will be extended in the future.
567 Multipath backend
569 Multipath backend in ssm is currently limited to only gather the infor‐
570 mation about multipath volumes in the system. You can not create or
571 manage multipath volumes or pools, but this functionality will be
572 extended in the future.
573
575 List system storage information:
576 # ssm list
578 List all pools in the system:
580 # ssm list pools
582 Create a new 100GB volume with the default lvm backend using /dev/sda
584 and /dev/sdb with xfs file system:
585 # ssm create --size 100G --fs xfs /dev/sda /dev/sdb
587 Create a new volume with a btrfs backend using /dev/sda and /dev/sdb
589 and let the volume to be RAID 1:
590 # ssm -b btrfs create --raid 1 /dev/sda /dev/sdb
592 Using the lvm backend create a RAID 0 volume with devices /dev/sda and
594 /dev/sdb with 128kB stripe size, ext4 file system and mount it on
595 /home:
596 # ssm create --raid 0 --stripesize 128k /dev/sda /dev/sdb /home
598 Create a new thinly provisioned volume with a lvm backend using devices
600 /dev/sda and /dev/sdb using --virtual-size option:
601 # ssm create --virtual-size 1T /dev/sda /dev/sdb
603 Create a new thinly provisioned volume with a defined thin pool size
605 and devices /dev/sda and /dev/sdb:
606 # ssm create --size 50G --virtual-size 1T /dev/sda /dev/sdb
608 Extend btrfs volume btrfs_pool by 500GB and use /dev/sdc and /dev/sde

611 # ssm resize -s +500G btrfs_pool /dev/sdc /dev/sde
613 Shrink volume /dev/lvm_pool/lvol001 by 1TB:
615 # ssm resize -s-1t /dev/lvm_pool/lvol001
617 Remove /dev/sda device from the pool, remove the btrfs_pool pool and
619 also remove the volume /dev/lvm_pool/lvol001:
620 # ssm remove /dev/sda btrfs_pool /dev/lvm_pool/lvol001
622 Take a snapshot of the btrfs volume btrfs_pool:my_volume:
624 # ssm snapshot btrfs_pool:my_volume
626 Add devices /dev/sda and /dev/sdb into the btrfs_pool pool:
628 # ssm add -p btrfs_pool /dev/sda /dev/sdb
630 Mount btrfs subvolume btrfs_pool:vol001 on /mnt/test:
632 # ssm mount btrfs_pool:vol001 /mnt/test

636 SSM_DEFAULT_BACKEND
637 Specify which backend will be used by default. This can be over‐
638 ridden by specifying the -b or --backend argument. Currently
639 only lvm and btrfs are supported.
640 SSM_LVM_DEFAULT_POOL
642 Name of the default lvm pool to be used if the -p or --pool
643 argument is omitted.
644 SSM_BTRFS_DEFAULT_POOL
646 Name of the default btrfs pool to be used if the -p or --pool
647 argument is omitted.
648 SSM_PREFIX_FILTER
650 When this is set, ssm will filter out all devices, volumes and
651 pools whose name does not start with this prefix. It is used
652 mainly in the ssm test suite to make sure that we do not scram‐
653 ble the local system configuration.

673 Python 2.6 or higher is required to run this tool. System Storage Man‐
674 ager can only be run as root since most of the commands require root
675 privileges.
676 There are other requirements listed below, but note that you do not
678 necessarily need all dependencies for all backends. However if some of
679 the tools required by a backend are missing, that backend will not
680 work.
