Why is my server crashing? "nfsd: non-standard errno: -103"

Featured Replies

Happened twice today. The first time, I just shutdown the server and made sure all disks were properly cabled. Everything was fine.

 

A few hours later (just now), the server is unresponse and I see this in the syslog:

WebUI works, SSH works. However shares are not found:

 

root@Tower:~# ls /mnt/user
/bin/ls: cannot access '/mnt/user': Transport endpoint is not connected

 

Diags attached.
