VolumeGroupName

 

DESCRIPTION

vgcfgrestore allows you to restore the metadata of VolumeGroupName
from a text backup file produced by vgcfgbackup.
You can specify a backup file with –file.
If no backup file is specified, the most recent
one is used. Use –list for a list of the available
backup and archive files of VolumeGroupName.
 

OPTIONS

See lvm(8) for common options.


-l, –list


List files pertaining to VolumeGroupName
List metadata backup and archive files pertaining to VolumeGroupName.
May be used with the -f option. Does not restore VolumeGroupName.
-f, –file filename


Name of LVM metadata backup file
Specifies a metadata backup or archive file to be used for restoring
VolumeGroupName. Often this file has been created with vgcfgbackup.
–force


Necessary to restore metadata with thin pool volumes.

WARNING: Use with extreme caution.
Most changes to thin metadata cannot be reverted.
You may lose data if you restore metadata that does not match the thin pool
kernel metadata precisely.


 

REPLACING PHYSICAL VOLUMES

vgdisplay –partial –verbose 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
pvcreate –restorefile filename –uuid uuid (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 vgcfgrestore –file filename to restore the volume
group’s metadata.
