\fBWARNING\fR: if lvm is already hung, then this script may hang as well if \fB\-a\fR is used

.TP
|
||
|
|
\fB\-m\fR \(em gather LVM metadata from the PVs
|
||
|
|
This option generates a 1:1 dump of the metadata area from all PVs visible to the system, which can cause the dump to increase in size considerably. However, the metadata dump may represent a valuable diagnostic resource.
|
||
|
|
.TP
|
||
|
|
\fB\-d\fR directory \(em dump into a directory instead of tarball
|
||
|
|
By default, lvmdump will produce a single compressed tarball containing all the information. Using this option, it can be instructed to only produce the raw dump tree, rooted in \fBdirectory\fP.
|
||
|
|
.TP
|
||
|
|
\fB\-c\fR \(em if clvmd is running, gather cluster data as well
