Correcting some usage of Bold and Italics (files). Adding some missing SEE ALSO. Fixing missed replaceable paths that are configurable. Be careful about .P in .TP sections - need to use .sp for space line. Use .UR/.UE for URL references.

.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.

.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.

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.

Comma-separated list of MD RAID specific options:

Wait MD device's resync, recovery or reshape action to complete

.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.
