Dear xfs experts, I really need your help sincerely!!! In our production enviroment we run glusterfs over top of xfs on Dell x720D(Raid 6). And the xfs file system crash on some of the server frequently about every two weeks. Can you help to give me a direction about how to debug this issue and how to avoid it? Thank you very very much! uname -a Linux cqdx.miaoyan.cluster1.node11.qiyi.domain 2.6.32-279.el6.x86_64 #1 SMP Wed Jun 13 18:24:36 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux Every time the crash log is same, as following 038 Apr 9 09:41:36 cqdx kernel: XFS (sdb): xfs_iunlink_remove: xfs_inotobp() returned error 22. 1039 Apr 9 09:41:36 cqdx kernel: XFS (sdb): xfs_inactive: xfs_ifree returned error 22 1040 Apr 9 09:41:36 cqdx kernel: XFS (sdb): xfs_do_force_shutdown(0x1) called from line 1184 of file fs/xfs/xfs_vnodeops.c.
