Use \fBpvscan\fP(8) to see which PVs lost their metadata.
|
|
Run \fBpvcreate\fP(8) with the \fB\-\-uuid\fP and \fB\-\-restorefile\fP
|
|
options on each such PV to reformat it as it was, using the archive
|
|
file that \fBvgconvert\fP(8) created at the start of the procedure.
|
|
Finally run \fBvgcfgrestore\fP(8) with that archive file to restore
|
|
the original metadata.
