Just a minor issue, but when I did some XFS tracing using the instructions at http://lwn.net/Articles/341899/ I found that there was trailing garbage in the filenames logged in xfs_lookup. Example: ... bonnie++-26179 [000] 322388.834204: xfs_iunlock: dev 8:32 ino 0xfe1e6 flags ILOCK_SHARED caller xfs_free_eofblocks bonnie++-26179 [000] 322388.834212: xfs_lookup: dev 8:32 dp ino 0xfb50d name 000000295aSl688>v??*N bonnie++-26179 [000] 322388.834213: xfs_ilock: dev 8:32 ino 0xfb50d flags ILOCK_SHARED caller xfs_ilock_map_shared ... (where I think the real filename was "000000295aSl688"). I would guess the logger is expecting null-terminated strings but they aren't. This is with the stock kernel from Ubuntu 11.10 server x86_64: Linux storage1 3.0.0-15-server #26-Ubuntu SMP Fri Jan 20 19:07:39 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Regards, Brian. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
