Hi All: I'm performing a rolling upgrade of one of our GPFS clusters. This particular cluster has 2 CNFS servers for some of our NFS clients. I wiped one of the nodes and installed RHEL 8.1 and GPFS 5.0.4.2. The filesystem mounts fine on the node when I disable CNFS on the node, but with it enabled it's a no go. It appears mmnfsmonitor doesn't recognize that nfsd has started, so it assumes the worst and shuts down the file system (I currently have reboot on failure disabled to debug this). The thing is, it actually does start nfsd processes when running mmstartup on the node. Doing a "ps" shows 32 nfsd threads are running.
Below is the CNFS-specific output from an attempt to start the node: CNFS[27243]: Restarting lockd to start grace CNFS[27588]: Enabling 172.16.69.76 CNFS[27694]: Restarting lockd to start grace CNFS[27699]: Starting NFS services CNFS[27764]: NFS clients of node 172.16.69.122 notified to reclaim NLM locks CNFS[27910]: Monitor has started pid=27787 CNFS[28702]: Monitor detected nfsd was not running, will attempt to start it CNFS[28705]: Starting NFS services CNFS[28730]: NFS clients of node 172.16.69.122 notified to reclaim NLM locks CNFS[28755]: Monitor detected nfsd was not running, will attempt to start it CNFS[28758]: Starting NFS services CNFS[28789]: NFS clients of node 172.16.69.122 notified to reclaim NLM locks CNFS[28813]: Monitor detected nfsd was not running, will attempt to start it CNFS[28816]: Starting NFS services CNFS[28844]: NFS clients of node 172.16.69.122 notified to reclaim NLM locks CNFS[28867]: Monitor detected nfsd was not running, will attempt to start it CNFS[28874]: Monitoring detected NFSD is inactive. mmnfsmonitor: NFS server is not running or responding. Node failure initiated as configured. CNFS[28924]: Unexporting all GPFS filesystems Any thoughts? My other CNFS node is handling everything for the time being, thankfully!
