Very odd that some kind of on-disk corruption is suddenly causing xfsdump problems starting with Ubuntu 10.04 (Lucid) kernel 2.6.32-27 and persisting in 2.6.32-28.

And there is one other person who confirmed this xfsdump problem running Lucid with kernel 2.6.32-28. They reported their "me too" in the Ubuntu bug tracker.

Could it be that 2.6.32-26 and prior managed to write something to disk corrupted, and the newer code is tripping on it?

I shall reboot the server to the 2.6.32-28 kernel and perform the tests you requested.

Sincerely,
