I'd managed to make a metadump using the 3.1.7 version of the tools. Then I
tried to run xfs_repair on the partition, and now xfs_metadump is segfaulting
on the partition.
Would the older metadata dump be useful?
I'd need to rebuild xfsprogs before the stack trace would be useful... debian
likes to strip the symbols and they didn't make a -dbg package.
