[gpfsug-discuss] mmhealth reports fserrinvalid errors on CNFS servers

[Prasad Surampudi]

We are seeing fserrinvalid error on couple of filesystems in Spectrum Scale cluster. These errors are reported but mmhealth  only couple of nodes  (CNFS servers) in the cluster, but mmhealth on other nodes shows no issues. Any idea what this error means? And why its reported on CNFS servers and not on other nodes? What need to be done to fix this issue?

sudo /usr/lpp/mmfs/bin/mmhealth node show FILESYSTEM -v

Node name:      cnfs05-gpfs
