vgcfgbackup

Ahmed Samy Amer — Tue, 15 May 2001 08:37:18 GMT

Hi Admins,

I'm getting this Error each time i do an LVM command that execute vgcfgbackup after the command:

vgcfgbackup: /etc/lvmtab is out of date with the running kernel:Kernel indicates 9 disks for "/dev/vgprod"; /etc/lvmtab has 8 disks.

lvmtab contains 8 disks fro vgprod and this is correct, but how to clean the Kernel data or fix it...i rebooted many times.

Thanks

Hi

#mv /etc/lvmtab /etc/lvmtab.orig
#vgscan

this could help.

#rm /etc/lvmtab
recreate it with:
#vgscan -v

I did vgscan and lvmtab was rebuilt successfully then vgcfgbackup is still reporting the same.

hi,
did you REMOVE the original /etc/lvmtab??
vgscan will not rebuild the lvmtab completely if the entries already exist!
regards,
Thierry.

ooops, sorry, I went for the obvious :(

okay, so I presume a disk has been removed?!
try "vgreduce -f /dev/vgxx" ; this will remove missing disks from the volume group.
(a new vgscan might be necessary afterwards)
this should do the trick,
good luck,
Thierry.
