Hi,

We have multiple 22 disk raid 6 arrays using LSI 9280-24i4e raid cards, all using enterprise grade drives. The array is setup with physical drive cache disabled and mounted using inode64 with nobarriers option in Oracle Linux Server release 6.6, kernel version 3.8.13-55.1.5.el6uek.x86_64. We are suffering from corruptions with xfs_repair unable to permanently fix the the issues. Output of dmesg from the latest corruption.

Pid: 5319, comm: glusterfsd Not tainted 3.8.13-55.1.5.el6uek.x86_64 #2
