That looks more like a blkid or udev problem. try using blkid -p so that it doesn't look up the cache but directly probes devices for the signatures. strace might tell you a bit more, too. And if the filesystem mounts, then it definitely isn't an XFS problem ;)
Thats the thing, it didn't mount, even when I used the device name directly.
Good point on stracing though. I'll do that tomorrow and report back. Thanks!
