blkdeactivate — utility to deactivate block devices
blkdeactivate [-d dm_options] [-e] [-h] [-l lvm_options] [-m mpath_options] [-r mdraid_options] [-o vdo_options] [-u] [-v] [device]
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.
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
