I've now tried the same repeater scenario against EXT2, EXT3, EXT4, and XFS formatted bricks. There's no change in behavior; the discriminating detail is still only whether the
build-pgfid volume option is on. Number of bricks, distribution over servers, transport protocol, etc., can all be changed over a wide range without affecting the scope or nature of failure.
Is there anyone using build-pgfid=on, doing any fine-grained small-file I/O (such as building sizable project from source), and *not* getting xattr errors in the brick logs / undeletable files due to incomplete xattr ops? Anyone? Anyone? Buhler? Buhler? From: LaGarde, Owen M ERDC-RDE-ITL-MS Contractor

Looks like the errors occur only when the gfid-to-path translation [volume option] is on. Is anyone else seeing this? Anyone using 3.6.6-1 with XFS-formatted bricks?

Update: I've tried a second cluster with AFAIK identical backing storage configuration from the LUNs up, identical gluster/xfsprogs/kernel on the servers, identical volume setup,
and identical kernel/gluster on the clients. The reproducer does not fail on the new system. So far I can't find any delta between the two clusters' setup other than the brick count (28 bricks across 8 servers on the failing one, 14 bricks across 4 servers
on the new one).
