NFSv4.1: NFS server returns NFS4ERR_OLD_STATEID for NFS client opening/closing files in rapid succession
Issue
- After migrating from NFSv3 to NFSv4.1, a third-party NFS server reports a RHEL NFS client as using an old sequence number for a stateid sequence id.
- The NFS server logs the NFS client as using an incorrect sequence id for a given stateid, but uses the correct sequence id after receiving NFS4ERR_OLD_STATEID.
- The NFS client reports no errors and there are no application issues accessing the NFS share.
Environment
- Red Hat Enterprise Linux (NFS client)
- RHEL 7.3 and later
- RHEL 8
- NFSv4.1 or later
- Any NFS server.
