|
|
kernel metadata precisely.\fP

|
.SH REPLACING PHYSICAL VOLUMES
|
|
\fBvgdisplay \-\-partial \-\-verbose\fP will show you the UUIDs and sizes of
|
|
any PVs that are no longer present.
|
|
If a PV in the VG is lost and you wish to substitute
|
|
another of the same size, use
|
|
\fBpvcreate \-\-restorefile filename \-\-uuid uuid\fP (plus additional
|
|
arguments as appropriate) to initialise it with the same UUID as
|
|
the missing PV. Repeat for all other missing PVs in the VG.
|
|
Then use \fBvgcfgrestore \-\-file filename\fP to restore the volume
|
|
group's metadata.
