For some NFSv4.1 clients, READ/WRITE fail, but directories can be traversed / listed
Applies to
- ONTAP 9
- NFSv4.1
- Linux client
Issue
- Specific NFSv4.1 clients lose the ability to perform READ/WRITE operations to an export
- Unmounting and remounting the export without changing mount options does not fix the issue, even if the impacted export was the only mounted export
- Packet captures collected when the issue is occurring show the client sending SEQUENCE calls, to which ONTAP sends back NFS4ERR_SEQ_MISORDERED
