BLKDEACTIVATE(8)                                         BLKDEACTIVATE(8)

NAME         top

       blkdeactivate — utility to deactivate block devices

SYNOPSIS         top

       blkdeactivate [-d dm_options] [-e] [-h] [-l lvm_options] [-m
       mpath_options] [-r mdraid_options] [-o vdo_options] [-u] [-v]
       [device]

DESCRIPTION         top

       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.

OPTIONS         top

       -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.

EXAMPLES         top

       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
