Try to bring the lvmetad usage text and man page closer to the code. There seem to be 3 useful ways to use -d with lvmetad at the moment: -d all -d wire -d debug (They can also be comma-separated like -d wire,debug.) Prior to the last release, -d, -dd and -ddd were supported. Fail if an unrecognised debug arg is supplied on the command line. Change -V to report the same version as the lvm binary: previously it just reported version 0.

.SH DESCRIPTION
|
|
lvmetad is a metadata caching daemon for LVM. The daemon receives notifications
|
|
from udev rules (which must be installed for LVM to work correctly when lvmetad
|
|
is in use). Through these notifications, lvmetad has an up-to-date and
|
|
consistent image of the volume groups available in the system.
|
|
|
|
By default, lvmetad, even if running, is not used by LVM. See \fBlvm.conf\fP(5).
|
|
.SH OPTIONS
|
|
.TP
|
|
.BR \-d " {" \fIall | \fIwire | \fIdebug }
|
|
Select the type of log messages to generate.
|
|
Messages are logged by syslog.
|
|
Additionally, when -f is given they are also sent to standard error.
|
|
Since release 2.02.98, there are two classes of messages: wire and debug.
|
|
Selecting 'all' supplies both and is equivalent to a comma-separated list
|
|
-d wire,debug.
|
|
Prior to release 2.02.98, repeating from 1 to 3 times, viz. -d, -dd, -ddd,
|
|
increased the detail of messages.
