blkdeactivate — utility to deactivate block devices
blkdeactivate [-d dm_options] [-e] [-h] [-l lvm_options] [-m mpath_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.
-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 to indicate the device was skipped. -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 the Volume Group as a whole is quicker than deactivating each Logical Volume separately. -m, --mpathoption 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 blkdeactivate may end up waiting if all the paths are unavailable for any underlying device-mapper multipath device. -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, 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
