.SH DESCRIPTION
.
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 \fBlvm\fP(8) command, the rest of device-mapper
based devices are handled using the \fBdmsetup\fP(8) command.
MD devices are handled using the \fBmdadm\fP(8) command.
.
.SH OPTIONS
.
.TP
.BR -d | --dmoptions " " \fIdm_options
Comma separated list of device-mapper specific options.
Accepted \fBdmsetup\fP(8) options are:
.RS
.TP
.B retry
Retry removal several times in case of failure.
.TP
.B force
Force device removal.
.RE
.
.TP
.BR -e | --errors
Show errors reported from tools called by \fBblkdeactivate\fP. Without this
option, any error messages from these external tools are suppressed and the
\fBblkdeactivate\fP itself provides only a summary message to indicate
the device was skipped.
.
.TP
.BR -h | --help
Display the help text.
.
.TP
.BR -l | --lvmoptions " " \fIlvm_options
Comma-separated list of LVM specific options:
.RS
.TP
.B retry
Retry removal several times in case of failure.
.TP
.B 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.
.RE
.
.TP
.BR -r | --mdraidoptions " " \fImdraid_options
Comma-separated list of MD RAID specific options:
.RS
.TP
.B wait
Wait MD device's resync, recovery or reshape action to complete
before deactivation.
.RE
.
.TP
.BR -m | --mpathoptions " " \fImpath_options
Comma-separated list of device-mapper multipath specific options:
.RS
.TP
.B 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.
.RE
.
.TP
.BR -o | --vdooptions " " \fIvdo_options
Comma-separated list of VDO specific options:
.RS
.TP
.BR configfile = \fIfile
Use specified VDO configuration file.
.RE
.
.TP
.BR -u | --umount
Unmount a mounted device before trying to deactivate it.
Without this option used, a device that is mounted is not deactivated.
.
.TP
.BR -v ", " --verbose
Run in verbose mode. Use \fB-vv\fP for even more verbose mode.
.
.SH EXAMPLES
.
Deactivate all supported block devices found in the system, skipping mounted
devices.
.br
#
.B blkdeactivate
.P
Deactivate all supported block devices found in the system, unmounting any
mounted devices first, if possible.
.br
#
.B blkdeactivate -u
.P
Deactivate the device /dev/vg/lvol0 together with all its holders, unmounting
any mounted devices first, if possible.
.br
#
.B blkdeactivate -u /dev/vg/lvol0
.P
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.
.br
#
.B blkdeactivate -u -d retry -l wholevg
.P
Deactivate all supported block devices found in the system. If the deactivation
of a device-mapper device fails, retry it and force removal.
.br
#
.B blkdeactivate -d force,retry
