error about VG

[rayche]

vgcfgbackup: /etc/lvmtab is out of date with the running kernel:Kernel indicates as 6 disks.
Now In my vg, current PV is 6, but active PV is 5.

How to check this problem ?

Thanks.

Rayche,

check with ,
# vgdisplay -v vg## | grep "PV Name"

and compare with ,
# strings /etc/lvmtab

And also check # ioscan -fnC disk for NO_HW , hope then you can locate the faulty/missing disk,


hth,
Raj.

hi,

1. check in lvmtab
# strings /etc/lvmtab
2. check VG configurations
# vgdisplay -v /dev/vg_name
is it any PV that unavailable or not
3. re-scan disk
# ioscan -nfCdisk
all disks are CLAIMED or NO_HW.check status of path disks that used by VG.

Some confusion out there in the kernel and disks actually configured.A possible screwup.

Anyway try this up.

1. Take a copy of lvmtab to lvmtab.org (Play safe)

2.do an "ioscan" "insf -e" and "vgscan -a" ,you should find a new lvmtab file created.And see if problem resolved,if not revert the lvmtab file.

Did you make changes like replacing a disk?

Sometimes this happens after an improper replacement procedure.

Please post a "strings /etc/lvmtab" and a "vgdisplay -v ".
