BLKDEACTIVATE(8) BLKDEACTIVATE(8)
blkdeactivate — utility to deactivate block devices
blkdeactivate [-d dm_options] [-e] [-h] [-l lvm_options] [-m
mpath_options] [-r mdraid_options] [-o vdo_options] [-u] [-v]
[device]
The blkdeactivate utility deactivates block devices. For mounted
block devices, it attempts to unmount it automatically before try‐
ing to deactivate. The utility currently supports device-mapper
devices (DM), including LVM volumes and software RAID MD devices.
LVM volumes are handled directly using the lvm(8) command, the
rest of device-mapper based devices are handled using the
dmsetup(8) command. MD devices are handled using the mdadm(8)
command.
-d|--dmoptions dm_options
Comma separated list of device-mapper specific options.
Accepted dmsetup(8) options are:
retry Retry removal several times in case of failure.
force Force device removal.
-e|--errors
Show errors reported from tools called by blkdeactivate.
Without this option, any error messages from these external
tools are suppressed and the blkdeactivate itself provides
only a summary message to indicate the device was skipped.
-h|--help
Display the help text.
-l|--lvmoptions lvm_options
Comma-separated list of LVM specific options:
retry Retry removal several times in case of failure.
wholevg
Deactivate the whole LVM Volume Group when process‐
ing a Logical Volume. Deactivating the Volume Group
as a whole is quicker than deactivating each Logical
Volume separately.
-r|--mdraidoptions mdraid_options
Comma-separated list of MD RAID specific options:
wait Wait MD device's resync, recovery or reshape action
to complete before deactivation.
-m|--mpathoptions mpath_options
Comma-separated list of device-mapper multipath specific
options:
disablequeueing
Disable queueing on all multipath devices before de‐
activation. This avoids a situation where blkdeac‐
tivate may end up waiting if all the paths are un‐
available for any underlying device-mapper multipath
device.
-o|--vdooptions vdo_options
Comma-separated list of VDO specific options:
configfile=file
Use specified VDO configuration file.
-u|--umount
Unmount a mounted device before trying to deactivate it.
Without this option used, a device that is mounted is not
deactivated.
-v, --verbose
Run in verbose mode. Use -vv for even more verbose mode.
Deactivate all supported block devices found in the system, skip‐
ping mounted devices.
# blkdeactivate
Deactivate all supported block devices found in the system, un‐
mounting any mounted devices first, if possible.
# blkdeactivate -u
Deactivate the device /dev/vg/lvol0 together with all its holders,
unmounting any mounted devices first, if possible.
# blkdeactivate -u /dev/vg/lvol0
Deactivate all supported block devices found in the system. If the
deactivation of a device-mapper device fails, retry it. Deactivate
the whole Volume Group at once when processing an LVM Logical Vol‐
ume.
# blkdeactivate -u -d retry -l wholevg
Deactivate all supported block devices found in the system. If the
deactivation of a device-mapper device fails, retry it and force
removal.
# blkdeactivate -d force,retry
