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)
