Синопсис (Synopsis)

[device]
Описание (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.
Параметры (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.
-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
deactivation. This avoids a situation where
blkdeactivate may end up waiting if all the paths
are unavailable 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.
Примеры (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 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
