# XFS corrupt again


Hmmm, this is the second time in 1 year that I had a corrupt filesystem
on my raid partition. I saw no other option than `mke2fs -j /dev/md7`.

My first problem with XFS started on my fileserver, which only had 256
MB of memory. Turns out XFS was OOM-ing inside the kernel, this in
turned messed up the filesystem. `xfs_repair` was also running out of
memory. When I finally got enough virtual memory in this box
`xfs_repair` was kind enough to segfault. Ok, shit happens, `mkfs.xfs`
and try again. 

I've moved the raid services off this under powered box and put the disks
in my normal server with 2 GB of memory. But today I wanted to remove
some old backups which heavily uses hardlinks. my guess is that there
are a few million on that (backup/raid) partition alone. This failed, it
started to spew out errors after having ran for an hour. 

OK.

I killed the `rm`, umounted the filesystem, mounted in again so that XFS
could recheck it. This worked; i.e. the filesystem was still OK. Next I
thought it would be a good idea to run `xfs_repair` again on it to
double check.

Then I went to work.

After coming home again, it *still* wasn't finished. OK. I got my USB
hard disk out, `cp`-ed the stuff over and:

    mke2fs -j /dev/md7
