NAME <\/a> <\/h2>\n

blkdeactivate \u2014 utility to deactivate block devices<\/p>\n

SYNOPSIS <\/a> <\/h2>\n

blkdeactivate<\/b> [\u2212d\u00a0<\/b>dm_options<\/i>] [\u2212e<\/b>] [\u2212h<\/b>] [\u2212l\u00a0<\/b>lvm_options<\/i>] [\u2212m\u00a0<\/b>mpath_options<\/i>] [\u2212r\u00a0<\/b>mdraid_options<\/i>] [\u2212o\u00a0<\/b>vdo_options<\/i>] [\u2212u<\/b>] [\u2212v<\/b>] [device<\/i>]<\/p>\n

DESCRIPTION <\/a> <\/h2>\n

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<\/b>(8) command, the rest of device-mapper based devices are handled using the dmsetup<\/b>(8) command. MD devices are handled using the mdadm<\/b>(8) command.<\/p>\n

OPTIONS <\/a> <\/h2>\n

\u2212d<\/b>, \u2212\u2212dmoptions\u00a0<\/b>dm_options<\/i><\/p>\n

Comma separated list of device-mapper specific options. Accepted dmsetup<\/b>(8) options are:<\/p>\n\n\n\n
<\/td>\n\n

retry<\/i><\/p>\n<\/td>\n

<\/td>\n\n

Retry removal several times in case of failure.<\/p>\n<\/td>\n<\/tr>\n

<\/td>\n\n

force<\/i><\/p>\n<\/td>\n

<\/td>\n\n

Force device removal.<\/p>\n<\/td>\n<\/tr>\n<\/table>\n

\u2212e<\/b>, \u2212\u2212errors<\/b><\/p>\n

Show errors reported from tools called by blkdeactivate<\/b>. Without this option, any error messages from these external tools are suppressed and the blkdeactivate<\/b> itself provides only a summary message to indicate the device was skipped.<\/p>\n

\u2212h<\/b>, \u2212\u2212help<\/b><\/p>\n

Display the help text.<\/p>\n

\u2212l<\/b>, \u2212\u2212lvmoptions\u00a0<\/b>lvm_options<\/i><\/p>\n

Comma-separated list of LVM specific options:<\/p>\n\n\n
<\/td>\n\n

retry<\/i><\/p>\n<\/td>\n

<\/td>\n\n

Retry removal several times in case of failure.<\/p>\n<\/td>\n<\/tr>\n<\/table>\n

wholevg<\/i><\/p>\n

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.<\/p>\n

\u2212m<\/b>, \u2212\u2212mpathoptions\u00a0<\/b>mpath_options<\/i><\/p>\n

Comma-separated list of device-mapper multipath specific options:
disablequeueing<\/i><\/p>\n

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.<\/p>\n

\u2212r<\/b>, \u2212\u2212mdraidoptions\u00a0<\/b>mdraid_options<\/i><\/p>\n

Comma-separated list of MD RAID specific options:<\/p>\n\n\n
<\/td>\n\n

wait<\/i><\/p>\n<\/td>\n

<\/td>\n\n

Wait MD device\u2019s resync, recovery or reshape action to complete before deactivation.<\/p>\n<\/td>\n<\/tr>\n<\/table>\n

\u2212o<\/b>, \u2212\u2212vdooptions\u00a0<\/b>vdo_options<\/i><\/p>\n

Comma-separated list of VDO specific options:
configfile=file<\/i><\/p>\n

Use specified VDO configuration file.<\/p>\n

\u2212u<\/b>, \u2212\u2212umount<\/b><\/p>\n

Unmount a mounted device before trying to deactivate it. Without this option used, a device that is mounted is not deactivated.<\/p>\n

\u2212v<\/b>, \u2212\u2212verbose<\/b><\/p>\n

Run in verbose mode. Use \u2212\u2212vv for even more verbose mode.<\/p>\n

EXAMPLES <\/a> <\/h2>\n

Deactivate all supported block devices found in the system, skipping mounted devices. # blkdeactivate<\/b><\/p>\n

Deactivate all supported block devices found in the system, unmounting any mounted devices first, if possible. # blkdeactivate \u2212u<\/b><\/p>\n

Deactivate the device \/dev\/vg\/lvol0 together with all its holders, unmounting any mounted devices first, if possible. # blkdeactivate \u2212u \/dev\/vg\/lvol0<\/b><\/p>\n

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 \u2212u \u2212d retry \u2212l wholevg<\/b><\/p>\n

Deactivate all supported block devices found in the system. If the deactivation of a device-mapper device fails, retry it and force removal. # blkdeactivate \u2212d force,retry<\/b><\/p>\n
