@Ray_Foss Hello again and a belated welcome to the Rockstor community.
Thanks for the nice clean report. But could you first try selecting at least one of the update channels and applying all the fixes their in as 3.9.1-0 (un updated latest iso) is now pretty old. Hopefully their should be a fix or 2 in there that addresses this issue and if not then we can take it from there.
Also it would help to confirm the installed Rockstor version after update via:
yum info rockstor
We did have some major changes around that time that may have affected this and are hopefully now fixed in both channels. See how that goes and also paste any relevant rockstor.log entries that look to indicate a mount or nfs failure.
I updated and created everything from scratch. Now things do mount automatically, but the NFS service is inaccessible remotely, unless I manually toggle it on and off. All the ports show up in netstat and I can connect to them with netcat from the client. It’s as if NFS server softlocked. After yet another reboot, everything worked normally.
I’ll post an update if I find anything while fixing the issue on the production server. It seems to be a problem with upgrading pools/shares/users from 3.9.1-0
