[Tariq Hasan_1]

Hi

Me again!

I have been re-mirroring root disk in vg00 onto a new, blank PV in vg00, and althgough the mirroring has been successful, I am getting the following:

vgcfgbackup: /etc/lvmtab is out of date with the running kernel:Kernel indicates 4 disks for "/dev/vg00"; /etc/lvmtab has 3 disks

can you help?

[Jupinder Bedi]

can you please let me know the steps , what to followed during disk replacement

and also you can try

rm /etc/lvmtab
vgscan -a

[Kanagaraj]

Mr Bedi said it right.

rename or remove the /etc/lvmtab file.
Then run vgscan -av

[Tariq Hasan_1]

There is no entry for vg00

Scan of Physical Volumes Complete.

*** LVMTAB has been created successfully.

*** If PV links are configured in the system.

*** Do the following to resync information on disk.

*** #1. vgchange -a y

*** #2. lvlnboot -R


Also, I cannot vgdisplay vg00 becuase of this:

SERVER_NAME(root):/etc#vgdisplay -v vg00

vgdisplay: Volume group "/dev/vg00" does not exist in the "/etc/lvmtab" file.

vgdisplay: Cannot display volume group "vg00"

[Jupinder Bedi]

have you saved the copy of previous lvmtab file . if yes than its ok

now try with

ioscan -fnC disk
and than
vgscan -a

[Jupinder Bedi]

and also do insf -e before ioscan

[Vishu]

Hi Tariq,

The cause of this problem is that 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 This error also indicates that the /etc/lvmtab file, which is used to match physical volumes to a volume group, is out of date with the LVM data structures in memory and on disk.

What you can do is to 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. when you found that bad disk just do.

# vgreduce -f

[TARUN SHARMA_1]

It seems that the 4th disk is nothing but the ghost disk, You should have removed it by -k option in lvreduce.
Now lvmtab is not existing so you need to recover it from backup if you have.

[Tariq Hasan_1]

Vishu

The vgeduce -f vg00 worked, I was then asked to move lvmtab, and vgscan.

I now have a fully working lvmtab.

Thanks everyone.

[Vishu]

you are welcome always.

But assigning points a good way to thanks to everyone who come forward to help you out.

[Tariq Hasan_1]
