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

23 -d, --dmoptions dm_options
24 Comma separated list of device-mapper specific options.
25 Accepted dmsetup(8) options are:
26 retry Retry removal several times in case of failure.
28 force Force device removal.
30 -e, --errors
32 Show errors reported from tools called by blkdeactivate. Without
33 this option, any error messages from these external tools are
34 suppressed and the blkdeactivate itself provides only a summary
35 message to indicate the device was skipped.
36 -h, --help
38 Display the help text.
39 -l, --lvmoptions lvm_options
41 Comma-separated list of LVM specific options:
42 retry Retry removal several times in case of failure.
44 wholevg
46 Deactivate the whole LVM Volume Group when processing a
47 Logical Volume. Deactivating the Volume Group as a whole
48 is quicker than deactivating each Logical Volume sepa‐
49 rately.
50 -m, --mpathoptions mpath_options
52 Comma-separated list of device-mapper multipath specific
53 options:
54 disablequeueing
56 Disable queueing on all multipath devices before deacti‐
57 vation. This avoids a situation where blkdeactivate may
58 end up waiting if all the paths are unavailable for any
59 underlying device-mapper multipath device.
60 -r, --mdraidoptions mdraid_options
62 Comma-separated list of MD RAID specific options:
63 wait Wait MD device's resync, recovery or reshape action to
65 complete before deactivation.
66 -o, --vdooptions vdo_options
69 Comma-separated list of VDO specific options:
70 configfile=file
72 Use specified VDO configuration file.
73 -u, --umount
76 Unmount a mounted device before trying to deactivate it. With‐
77 out this option used, a device that is mounted is not deacti‐
78 vated.
79 -v, --verbose
81 Run in verbose mode. Use --vv for even more verbose mode.
82
84 Deactivate all supported block devices found in the system, skipping
85 mounted devices. # blkdeactivate
86 Deactivate all supported block devices found in the system, unmounting
88 any mounted devices first, if possible. # blkdeactivate -u
89 Deactivate the device /dev/vg/lvol0 together with all its holders,
91 unmounting any mounted devices first, if possible. # blkdeactivate -u
92 /dev/vg/lvol0
93 Deactivate all supported block devices found in the system. If the
95 deactivation of a device-mapper device fails, retry it. Deactivate the
96 whole Volume Group at once when processing an LVM Logical Volume. #
97 blkdeactivate -u -d retry -l wholevg
98 Deactivate all supported block devices found in the system. If the
100 deactivation of a device-mapper device fails, retry it and force
101 removal. # blkdeactivate -d force,retry
