Summary: endless xfs_repiar loop
Product: Linux XFS
Version: Current
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: xfsprogs
AssignedTo: xfs-master@xxxxxxxxxxx
ReportedBy: glaucon.hunn@xxxxxxxxx
distro: debian etch
kernel: 2.6.26-1-686 (etch version)
xfsprogs: 2.9.8-1
(also ran memtest86+ overnight, everything looked good)
summary:
xfs_repair (lots of errors reported but seems to exit ok with "done")
xfs_repair (more errors...)
xfs_repair (more errors...)
...
The other day I thought it might be a good Idea to run xfs_repair on my 2.8T
(mdadm) raid6 filesystem. Mainly because xfs_check wont work because I dont
have enough memory... (nothing seemed broken just thought it would be a good
idea)
So I ran xfs_repair -n, it segfaulted due to a (seemingly) corrupt filesystem.
I say seemingly because I have no idea how it got corrupt... Anyways re-ran
without the -n to let it do its magic, it threw a bunch of files in lost+found/.
When I ls'ed them the kernel oopsed with things like:

So I unmounted, re-ran xfs_repair, it found a bunch more problems. So without
remounting I re-ran xfs_repiar -n, found more problems, ran xfs_repair... rinse
and repeat... Meanwhile I keep loosing more and more data (started out with
about > 1T on disk now down to ~500G in lost+found and ~100 left in the
filesystem)
Now im using xfs_copy and getting oops on the dest filesystem (due to the src
being corrupted?):
