So I ran an xfs_repair -v on my filesystem. While the FS was originally 12T
and 95% full. I ran xfs_repair and it throw many "out of space errors" when
it was running. That makes some sense.
I expanded it with a new device with xfs_grow. It seems to work, because the
disk is now bigger when I mount it.
When I ran xfs_repair on that (latest version), it reverts back to the
original size. Is there anything I need to do to make the xfs_growfs
If I can make the XFS partition bigger, I can likely make it work because
then it won't run out of space! But the partition, despite saying its
"bigger" here, doesn't seem to "take" after the xfs_repair. Any ideas?
Below is the xfs_db and some other useful things.
