NAME
blkdeactivate -- utility to deactivate block devices
SYNOPSIS
blkdeactivate [-d dm_options] [-e] [-h] [-l lvm_options] [-m mpath_options]
[-r mdraid_options] [-o vdo_options] [-u] [-v] [device]
DESCRIPTION
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.
OPTIONS
-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 deac-
tivation.
-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.
EXAMPLES
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 pro-
cessing 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
