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 automati‐
       cally 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 de‐
	      vice 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  blkdeac‐
		     tivate  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.

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
