Commitsa29bb6a14b...5c199d99f4narrowed down on addressing the escaping of hyphens in the dynamic creation of manuals whilst avoiding them in creating help texts. This lead to a sequence of slipping through hyphens adrressed by additional patches in aforementioned commit series. On the other hand, postprocessing dynamically man-generator created and statically provided manuals catches all hyphens in need of escaping. Changes: - revert the above commits whilst keeping man-generator streamlining and the detection of any '\' when generating help texts in order to avoid escapes to slip in - Dynamically escape hyphens in manaual pages using sed(1) in the respective Makefile targets - remove any manually added escaping on hyphens from any static manual sources or headers

.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 ", " --dmoption \ \fIdm_options\fP
|
|
Comma separated list of device-mapper specific options.
|
|
Accepted \fBdmsetup\fP(8) options are:
|
|
.RS
|
|
.IP \fIretry\fP
|
|
Retry removal several times in case of failure.
|
|
.IP \fIforce\fP
|
|
Force device removal.

.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 ", " --lvmoption \ \fIlvm_options\fP
|
|
Comma-separated list of LVM specific options:
|
|
.RS
|
|
.IP \fIretry\fP
|
|
Retry removal several times in case of failure.
|
|
.IP \fIwholevg\fP
|
|
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.

|
.TP
|
|
.BR -m ", " --mpathoption \ \fImpath_options\fP
|
|
Comma-separated list of device-mapper multipath specific options:
|
|
.RS
|
|
.IP \fIdisablequeueing\fP
|
|
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.

|
|
.BR -u ", " --umount
|
|
Unmount a mounted device before trying to deactivate it.
|
|
Without this option used, a device that is mounted is not deactivated.

.BR -v ", " --verbose
|
|
Run in verbose mode. Use --vv for even more verbose mode.
