Hi Joseph,
We have total 7 nodes and this problem occurs in multiple nodes simultaneously not in particular one node. we checked network and its fine.
When we remount the ocfs2 partition, this problem is get fixed temporarily and same problem reoccurs after some time.
Even we do have problem while unmountinng. umount process goes to "D" stat, then i need to restart server itself. Is there any solution for this issue.
I have tried running fsck.ocfs2 in problematic machine but its throwing error.
fsck.ocfs2 1.8.0
fsck.ocfs2: I/O error on channel while opening "/zoho/build/downloads"
Please refer the latest logs from one node.
