blkdeactivate - utility to deactivate block devices
SYNOPSIS
blkdeactivate [options] [device...]
DESCRIPTION
blkdeactivate utility deactivates block devices. If a device is
mounted, the utility can unmount it automatically before trying to
deactivate. The utility currently supports device-mapper devices,
including LVM volumes. LVM volumes are handled directly using the lvm
command. Other device-mapper based devices are handled using the
dmsetup command.
OPTIONS-e, --errors
Show errors reported from tools called by blkdeactivate. With‐
out this option, any error messages from these external tools
are suppressed and the blkdeactivate itself provides only a sum‐
mary message about device being skipped or not.
-h, --help
Display the help text.
-u, --umount
Unmount a mounted device before trying to deactivate it. With‐
out this option used, a device that is mounted is not deacti‐
vated.
-v, --verbose
Run in verbose mode.
-d, --dmoption dm_options
Comma separated list of device-mapper specific options.
-l, --lvmoption lvm_options
Comma separated list of LVM specific options.

wholevg
Deactivate the whole LVM Volume Group when processing a Logical

devices processed is mounted, unmount it first if possible.
blkdeactivate -u /dev/vg/lvol0
Deactivate all supported block devices found in the system. Retry deac‐
tivation of device-mapper devices in case the deactivation fails. Deac‐
tivate the whole Volume Group at once when processing an LVM Logical
Volume.
blkdeactivate -u -d retry -l wholevg

tivation of device-mapper devices in case the deactivation fails and
