Hello

I'm somewhat a newbie at LVM and have encountered a real problem for me.
during resize2fs after extending my LV i ended up with a crash. Now I'm
worried I have lost all my old data.
How can i proceed to get the volume in working order?
Any help would be greatly appreciated.

NoFear ~ # lvextend -L+400G /dev/vgftp/lvftp
Extending logical volume lvftp to 4.16 TiB
Logical volume lvftp successfully resized

Please run 'e2fsck -f /dev/vgftp/lvftp' first.

Resizing the filesystem on /dev/vgftp/lvftp to 1115800576 (4k) blocks.
** CRASH / HANG **

25hours waiting and nothing happens. No disk I/O going on or anything.
I have no backups or anything of this volume. What can i do do revert the
process to get the disks back? I have not done anything at all after the
crash/hang in fear of destroying something.

Thanks for any input
