Message Text
vgcfgbackup: /etc/lvmtab is out of date with the running kernel:
Kernel indicates # disks for "/dev/vgname"; /etc/lvmtab has # disks.
Cannot proceed with backup.
Cause
The number of current physical volumes (Cur PV) and active physical volumes (Act PV) are not
the same. Cur PV and Act PV must always agree for the volume group. This error also indicates
that /etc/lvmtab or /etc/lvmtab_p, which is used to match physical volumes to a volume
group, is out of date with the LVM data structures in memory and on disk.
Recommended Action
Try to locate any missing disks. For each of the disk in the volume group, use ioscan and
diskinfo to confirm that the disk is functioning properly.

Message Text
lvextend: Not enough free physical extents available.
Logical volume "/dev/vgname/lvname" could not be extended.
Failure possibly caused by strict allocation policy
Cause
There is not enough space in the volume group to extend the logical volume to the requested size.
This is typically caused by one of the following situations:
1. There are not enough free physical extents in the volume group. Run vgdisplay to confirm
the number of available physical extents, and multiply that number by the extent size to
determine the free space in the volume group. For example:
# vgdisplay vg00
--- Volume groups ---
VG Name /dev/vg00
VG Write Access read/write
VG Status available
Max LV 255
Cur LV 10
