Hi,

When execute:

#vgcfgbackup /dev/vg02
vgcfgbackup: /etc/lvmtab is out of date with the running kernel:Kernel indicate.
Cannot proceed with backup.

As I can resolve this problem?

I have used vgexport and vgimport and continuous the problem.

Thanks.

did you use the exact command as

vgcfgrestore -n vg02 /dev/rdsk/cXtXdX ??

Can you run

# vgdisplay

and

# vgdisplay /dev/vg02

You can try the below ,

1)backup current lvmtab using

cp -p /etc/lvmtab /etc/lvmtab.org

2)rm /etc/lvmtab

3)vgscan -v

Vgscan will create the new LVM tab with all the VGs.

4)compare the o/p of strings /etc/lvmtab and strings /etc/lvmtab.org

If everything looks good try the vgcfgresore on vg02 again .If succeful the you are set .

In case of any issues replace /etc/lvmtab with /etc/lvmtab.org backup file and try to fix the vg02 problem, you may export and import it again.

thx,
bl.

Hi,

Can you paste the vgdisplay -v output. You might see a difference in ACT PV and CUR PV

Thanks

Hi,

Any recent changes ? Perhaps some disk has been changes recently ?

Can you post "strings /etc/lvmtab" For current and old lvmtab file.

HTH,

Hi,

The problem here is quite clear and it describes that one of the disk was replaced in vg02 recently. That is the reason in vgdisplay output it is showing 5 PV's whereas in lvmtab and currently active PV's are only four.

If this was the case you can reduce the VG from the extra disk (Old one allready replaced)by

#vgreduce -f /dev/vg02

HTH,
Devender

Sreedhar Nathani — Tue, 04 Oct 2005 06:48:52 GMT

Hi,

vgdisplay -v
Cur PV 5
Act PV 4

** Kernel thinks this volume group has 5 disks, but lvmtab contains only 4 disks.

/dev/vg02
/dev/dsk/c0t14d0
/dev/dsk/c1t4d0
/dev/dsk/c1t12d0
/dev/dsk/c1t13d0

Incase if you don't have any problem with the filesystem mounting in this volume group
and no ??? marks against the lvdisplay -v /dev/vg02/ then you can do this

#cp /etc/lvmtab
#vgreduce -f /dev/vg02
#mv /etc/lvmtab /etc/lvmtab.old
#vgscan -av

>> After that you can take vgcfgbackup

Thanks
