error message when back up a volume group
xcaret.root:/etc/lvmconf>vgcfgbackup vg01
vgcfgbackup: /etc/lvmtab is out of date with the running kernel:Kernel indicates 7 disks for "/dev/vg01"; /etc/lvmtab has 6 disks.
Cannot proceed with backup.
xcaret.root:/etc/lvmconf>
How do I resolve this?
Thank You.

Re: error message when back up a volume group
If I was you, I probably do and vgexport -m -p vg01.map /dev/vg01. This export data of volume group, then vgexport vg01, and finally vgimport -m vg01.map /dev/vg01 (first create /dev/vg01 and recreate group file (mknod /dev/vg01/group c 64 0x010000)).
This will export vg01 from your config and then imports it with all disks that had the same vgid.
Very Importat, Backup all data first. This operation do not loose info, but and accident can happen.
Best Luck

Re: error message when back up a volume group
have you tried using "vgscan"?
Move that "/etc/lvmtab" to another place/name
and start "vgscan -v". Then you will get a new
and current one.

Re: error message when back up a volume group
Looks like what you did was put the new disk a different Id than the failed disk and added the new disk in the VG rather than doing a vgcfgrestore to the new disk.
So now our lvmtab shows the old disk as well as the new disk. Do a "strings /etc/lvmtab" and see the disks mentioned in the VG you are talking about.
Hope this helps.
Thanks
