Andrew had some dmesg output in bugzilla (please send this stuff to the list instead of hiding it in bugzilla if possible, BTW) that looks quite interesting: May 24 08:48:00 (none) last message repeated 61 times May 24 08:48:47 (none) last message repeated 760 times May 24 08:50:55 (none) kernel: reconnect_path: npd != pd May 24 08:50:55 (none) last message repeated 9 times May 24 08:55:04 (none) kernel: reconnect_path: npd != pd May 24 08:56:05 (none) last message repeated 47 times May 24 08:56:49 (none) last message repeated 419 times which means we are in deep trouble with the dcache coherency. Also the only way the bug you two report could happen from my audit is we get ->destroy_inode called twice for the same inode. So defintively some deep problems here. Alex and Andrew, can you send me your .config, and a description of the workload your seing this on? Also the /etc/exports file would be interesting. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
