Replacing A Missing Physical Volume - Red Hat Cluster Suite 4.7 Cluster Logical Volume Manager Manual

physical volume label with the metadata information contained in VG_00050.vg, the most recent
good archived metatdata for volume group . The restorefile argument instructs the pvcreate
command to make the new physical volume compatible with the old one on the volume group,
ensuring that the the new metadata will not be placed where the old physical volume contained data
(which could happen, for example, if the original pvcreate command had used the command line
arguments that control metadata placement, or it the physical volume was originally created using a
different version of the software that used different defaults). The pvcreate command overwrites only
the LVM metadata areas and does not affect the existing data areas.
[root@link-07 backup]# pvcreate --uuid "FmGRh3-zhok-iVI8-7qTD-S5BI-MAEN-
NYM5Sk" --restorefile /etc/lvm/archive/VG_00050.vg /dev/sdh1
Physical volume "/dev/sdh1" successfully created
You can then use the vgcfgrestore command to restore the volume group's metadata.
[root@link-07 backup]# vgcfgrestore VG
Restored volume group VG
You can now display the logical volumes.
[root@link-07 backup]# lvs -a -o +devices
LV VG Attr
stripe VG -wi--- 300.00G
(0),/dev/sda1(0)
stripe VG -wi--- 300.00G
(34728),/dev/sdb1(0)
The following commands activate the volumes and display the active volumes.
[root@link-07 backup]# lvchange -ay /dev/VG/stripe
[root@link-07 backup]# lvs -a -o +devices
LV VG Attr
stripe VG -wi-a- 300.00G
(0),/dev/sda1(0)
stripe VG -wi-a- 300.00G
(34728),/dev/sdb1(0)
If the on-disk LVM metadata takes as least as much space as what overrode it, this command can
recover the physical volume. If what overrode the metadata went past the metadata area, the data
on the volume may have been affected. You might be able to use the fsck command to recover that
data.

6.5. Replacing a Missing Physical Volume

If a physical volume fails or otherwise needs to be replaced, you can label a new physical volume to
replace the one that has been lost in the existing volume group by following the same procedure as
