The LVM meta-data is stored in a reserved area on each LVM disk. It contains data which describes the layout of each logical volume within a volume group.

To recreate lvmtab:
1) mv /etc/lvmtab /etc/lvmtab.save
2) vgscan

hi bhushi,

try this,

#vgreduce -f /dev/vg02 #mv /etc/lvmtab /etc/lvmtab.old (move corrupted BUT important file)
#vgscan -v (creates new clean lvmtab)
#vgcfgbackup /dev/vg02 (backups the data for vg02 )

There should be no errors with vgcfgbackup

now it will be updated.

I think it will work.
