Appendix B: LVM Error Messages

This appendix lists some of the warning and error messages reported by LVM. For each message, the cause is

listed, and an administrator action is recommended. The appendix is divided into two sections, one for LVM

command errors, and one for the system log file /var/adm/syslog/syslog.log error messages.

LVM Command Error Messages

All LVM commands

vgcfgbackup: /etc/lvmtab is out of date with the running kernel: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 and active physical volumes, printed by vgdisplay as Cur PV and Act PV,

are not the same. Cur PV and Act PV must always agree for the volume group. This error also

indicates that the /etc/lvmtab file, 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out of date with the LVM data structures in memory and on disk.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.

lvchange

"m": Illegal option.

Cause:

The system does not have HP MirrorDisk/UX installed.

Recommended Action:

Install HP MirrorDisk/UX.

lvextend

lvextend: Not enough 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 three situations:

a. 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
