I was thinking we can recover from this using re-sync or resize .After running IO to degraded (RAID-5) /dev/md0, I am seeing an issue where e2fsck reports inconsistent file system and corrects it. I am trying to debug to see if the issue is because of data not being written or reading wrong data in degraded mode. I guess problem happening during the write. Reason is , after ran e2fsck I don't see inconsistency any more.
