So I have run across a strange situation which I hope there are some
gurus out there to help.
The original setup was a logical volume of 8.9TB. I extended the volume
to 17.7TB and attempted to run xfs_growfs. I am not sure whether the
command actually finished, as after I ran the command, the metadata was
displayed, but there was no nothing that stated the the number of data
blocks had changed. I was just returned to the prompt, so I'm not sure
whether the command completed or not..
I was unable write to the logical volume I had just created. I tried to
remount it, but I kept getting an error saying the superblock could not
be read. I tried running an xfs_repair on the filesystem, and get the
Phase 1 - find and verify superblock...
superblock read failed, offset 19504058859520, size 2048, ag 64, rval 0
fatal error -- Invalid argument
I am not very experienced with xfs (I was following commands in some
documentaion), and I was recommended to post to this mailing list. If
anyone could provide some help, it would be greatly appreciate. Also,
if there is any information I can provide to help, I will gladly provide
it. Thanks in advance!
