Description
There's a number of reports from the field that NFS servers sometimes complain
MDT0000: Cannot find sequence 0x200000001: rc = -2
and nfs clients get ESTALE on access randomly.
This is widely believed is related to lustre sometimes returning invalid parent fid in the form of SEQ_LOCALFILE:REMOTE_PARENT_DIR_OID
Oftentimes reports say that if you do ls in the problematic dir on the lustre client/nfs server node problems go away hinting there's some cache-related interaction.
It would be good to understand and fix this.
