[Ocfs2-users] Issue with OCFS2 mount
We have an HP P2000 G3 Storage array, fiber connected. The storage array has a RAID5 array broken into 2 physical OCFS2 volumes (A B). A B are both mounted and formatted as NTFS. One of the volumes is NFS mounted. Every couple of months or so we start getting tons of errors on the NFS mounted volume: Aug 24 09:48:13 FILEt2 kernel: [2234285.848940] (ocfs2_wq,13844,7):ocfs2_block_check_validate:443 ERROR: CRC32 failed: stored: 0, computed 1467126086.

Has anyone had a similar experience and be able to share some insight and knowledge on any tricks with NFS and OCFS2 volumes?
