NFS client fails to mount or issue I/O to export provided by RHEL 7 High Availability cluster node after node has rebooted and reports error "getfh failed: Function not implemented"
Issue
- Red Hat 7 Pacemaker cluster node gets "getfh failed: Function not implemented" error when trying to map resources to an IO client after a node reboot or node power cycle.
- If a cluster node providing NFS exports reboots, rejoins the cluster, and starts up the
exportfsresource, clients fail to mount or issue I/O to that export. - NFS client reports "mount.nfs: access denied by server while mounting" and server reports "getfh failed: Function not implemented" after server node reboots.
Environment
- Red Hat Enterprise Linux (RHEL) 7 with the High Availability Add On
pacemaker- Cluster
exportfsresource(s) exporting NFS shares
