Hi,
My XFS home drive is corrupt after trying to extend it with lvm.
This is what I did to extend the partition.
1. Extend Volume group to use a new physical volume of around 1.2TB.
This was successful without any error.
vgextend vg-1 /dev/sdc1
2. Extend logical volume (home-lv) to use the free space.
lvextend -l 100%FREE /dev/mapper/vg--1-home--lv -r
3. Resized home-lv and reduce 55 GB
lvreduce -L 55G /dev/mapper/vg--1-home--lv -r
I assumed that -r will invoke xfs_grow internally.
Everything was working fine until the server was restarted.
After restart, the home volume is not mounting. Please see the following.
server% sudo mount -t xfs /dev/mapper/vg--1-home--lv /home
mount: /home: can't read superblock on /dev/mapper/vg--1-home--lv.
server% dmesg| tail

I have gone through the earlier posts on this subject. They did not help me.
Is it possible to repair the XFS volume? Kindly suggest.
