It looks like there is a bug in the test script, where it is using the filename instead of the FID for open-by-fid in some cases. Not sure why it is inconsistent.

My guess is the unknown sequence error is because the "fid" that is passed coincidentally has "f" at the start, and somehow gets interpreted as 0xf00000400?

If that is not the case, then there may be a more serious underlying problem, so we'd like some investigation (hopefully today) to determine the root cause.

In change http://review.whamcloud.com/5298 the prohibition to setxattr on .lustre and .lustre/fid was removed so the 2.3.0 check to ensure it fails is no longer valid for 2.4 MDTs (2.3.64 and following).

[Nathaniel Clark]

Should I submit a patch on b2_3 to fix this?
