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 trying
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 processing a
Logical Volume. Deactivating the Volume Group as a
whole is quicker than deactivating each Logical Volume
separately.
-m, --mpathoptions mpath_options
Comma-separated list of device-mapper multipath specific
options:
disablequeueing
Disable queueing on all multipath devices before
deactivation. This avoids a situation where
blkdeactivate may end up waiting if all the paths are
unavailable for any underlying device-mapper multipath
device.
-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.
-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, skipping
mounted devices. # blkdeactivate
Deactivate all supported block devices found in the system,
unmounting 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 Volume.
# 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
