6 blkdeactivate — utility to deactivate block devices

13 The blkdeactivate utility deactivates block devices. For mounted block
14 devices, it attempts to unmount it automatically before trying to deac‐
15 tivate. The utility currently supports device-mapper devices (DM), in‐
16 cluding LVM volumes and software RAID MD devices. LVM volumes are han‐
17 dled directly using the lvm(8) command, the rest of device-mapper based
18 devices are handled using the dmsetup(8) command. MD devices are han‐
19 dled using the mdadm(8) command.

22 -d, --dmoptions dm_options
23 Comma separated list of device-mapper specific options. Ac‐
24 cepted dmsetup(8) options are:
25 retry Retry removal several times in case of failure.
27 force Force device removal.
29 -e, --errors
31 Show errors reported from tools called by blkdeactivate. Without
32 this option, any error messages from these external tools are
33 suppressed and the blkdeactivate itself provides only a summary
34 message to indicate the device was skipped.
35 -h, --help
37 Display the help text.
38 -l, --lvmoptions lvm_options
40 Comma-separated list of LVM specific options:
41 retry Retry removal several times in case of failure.
43 wholevg
45 Deactivate the whole LVM Volume Group when processing a
46 Logical Volume. Deactivating the Volume Group as a whole
47 is quicker than deactivating each Logical Volume sepa‐
48 rately.
49 -m, --mpathoptions mpath_options
51 Comma-separated list of device-mapper multipath specific op‐
52 tions:
53 disablequeueing
55 Disable queueing on all multipath devices before deacti‐
56 vation. This avoids a situation where blkdeactivate may
57 end up waiting if all the paths are unavailable for any
58 underlying device-mapper multipath device.
59 -r, --mdraidoptions mdraid_options
61 Comma-separated list of MD RAID specific options:
62 wait Wait MD device's resync, recovery or reshape action to
64 complete before deactivation.
65 -o, --vdooptions vdo_options
68 Comma-separated list of VDO specific options:
69 configfile=file
71 Use specified VDO configuration file.
72 -u, --umount
75 Unmount a mounted device before trying to deactivate it. With‐
76 out this option used, a device that is mounted is not deacti‐
77 vated.
78 -v, --verbose
80 Run in verbose mode. Use --vv for even more verbose mode.
81
83 Deactivate all supported block devices found in the system, skipping
84 mounted devices. # blkdeactivate
85 Deactivate all supported block devices found in the system, unmounting
87 any mounted devices first, if possible. # blkdeactivate -u
88 Deactivate the device /dev/vg/lvol0 together with all its holders, un‐
90 mounting any mounted devices first, if possible. # blkdeactivate -u
91 /dev/vg/lvol0
92 Deactivate all supported block devices found in the system. If the de‐
94 activation of a device-mapper device fails, retry it. Deactivate the
95 whole Volume Group at once when processing an LVM Logical Volume. #
96 blkdeactivate -u -d retry -l wholevg
97 Deactivate all supported block devices found in the system. If the de‐
99 activation of a device-mapper device fails, retry it and force removal.
