Project Description

Overall: Existing NFS-HA Consulting solution exists (for SLES15 SP1 and SP2+) and is in production at customers. Goal is to improve this solution, enhance the documentation and make it more robust.

Goal for this Hackweek

  • Rewrite and cleanup existing documentation of this solution in ASCII-DOC
  • Test with SLES15 SP4 and new NFS Kernel server features introduced (unshare/hostname, NFS v4, NFSV4LEASETIME etc.)
  • make sure "waitforleasetimeonstop" is NOT set to true on the exportfs primitive
  • Add nfsdcltrack handling
  • Use NFS exports from /etc/exports instead of ocf:heartbeat:exportfs (should make CIB simpler)

Resources

  • Bug 1203746 - SLES15-SP4 60s NFS timeout during cluster failover | _nfs4reclaimopenstate: Lock reclaim failed!
