Hello,
I recently attempted to extend my logical volume. First I added an
additional physical volume to an existing volume group. This worked fine.
vgextend Volume00 /dev/sba
lvextend -L+100G /dev/Volume00/LogVol00
However when it came time to run the lvextend command I received a
number of device-mapper errors. While I was trying to determine what
the errors were I noticed that the filesystem that sits on the logical
volume being extended was no longer available. I attempted to umount
the filesystem however the command froze. I then rebooted the system
without mounting the filesystem in question and manually mounted the
filesystem. XFS reported back that it could not locate the superblock.
I attempted to run xfs_repair however this command failed at the first
stage because it could not find the superblock.
Is it possible to repair this problem either through LVM or XFS? I
noticed there are a number of achieved .vg files in /etc/lvm/archive ,
is it possible to restore LVM from one of these?
I am not running any snapshot copies, which is where I've read this
occurring before.
Thanks,
Frank
