blkdeactivate — utility to deactivate block devices
blkdeactivate [−d dm_options] [−e] [−h] [−l lvm_options] [−u] [−v] [device]
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(8) command. Other device-mapper based devices are handled using the dmsetup(8) command.
−d, −−dmoption 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 about device being skipped or not.
−h, −−help
Display the help text.
−l, −−lvmoption 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 Volume Group as a whole takes less time than deactivating each Logical Volume separately.
−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.
Deactivate all supported block devices found in the system. If a device is mounted, skip its deactivation.
blkdeactivate
Deactivate all supported block devices found in the system. If a device is mounted, unmount it first if possible.
blkdeactivate −u
Deactivate supplied device together with all its holders. If any of the devices processed is mounted, unmount it first if possible.
blkdeactivate −u /dev/vg/lvol0
Deactivate all supported block devices found in the system. Retry deactivation of device-mapper devices in case the deactivation fails. 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. Retry deactivation of device-mapper devices in case the deactivation fails and force removal.
