Hi,
I could not figure out whats happened on 01 May on our production server.
We've 2 pool on storage. One of is giant 12x4TB array (tank1) and the other one is single SSD drive (480GB) pool which name is "tank4".
Suddenly, tank4 became unavailable at 11:00 am. Actually it won't be a problem because all kinds of stuff stored in tank1 but all entire NFS service crashed due to tank4 failure. Each application who try to connect NFS on our application site throwed an error until we reset to server from power button.
We could not stop/start NFS service over GUI.
We could not restart NFS service over CLI.
When I checked 'ps aux | grep nfs', process 1886 stucked as running. When I tried to kill 1886, nothing changed. It nailed there!
Everytime I get an error like that;
When I tried to reboot system over CLI, it still tried to stop that process :)
So I have to reset over power button.
Now, I collect all logs during failure so maybe some of our guru's could explain.
