NFS server rash on cyclone.hpc.uib.no and grunch.hpc.uib.no server

•
Dear Cyclone and Grunch server users,

Our NFS server crashed again while we are debugging NFS hang problem.

Both servers are rebooted.

We have changed some of the optimization parameters for our NFS server, and we hope that this will help to eliminate the issue.

Update: 12:50 NFS on both cyclone and grunch are stable so far. we have done some changes for NFS configuration.

Update : 14:00 Unfortunately the problem is not resolved. we are working on it. login to both server is disabled.

Update: 18.11.2019 09:00 : Home directories are mounted on both Cyclone and Grunch,  NFS mounts should be stable.
