OK - the error message shown unfortunately means little to me, so we’ll need to fall back to logs to find out what’s going on.
First thing’s first, please check to ensure that the Rock-on service is enabled in
System -> Services
If it’s not, enable it, wait a minute and try again.
If you’re still having trouble, we need to get the logs as I mentioned earlier.
It looks like your web UI to system shell (“shell-in-a-box”) service is broken or is not configured.
Please navigate to
System -> Services, locate “Shell In A Box”.
Click the spanner next to the name, and use the settings:
Submit, and then ensure that the service switch is ‘On’. (Click to change it if it’s not)
Give it a couple of minutes, then try and access the system shell again.
Assuming you can get into the system shell, you should be able to login with the same credentials you use for the Rockstor UI.
I would like you to type the following:
sudo tail -n 0 -f /opt/rockstor/var/log/rockstor.log
You will likely be asked for a sudo password, you can enter your UI password again here.
From there, open a new tab (We need to leave this shell open!), and navigate to the Rockstor UI.
Attempt to perform the same actions again in order to get the on-screen error message.
Go back to the shell tab, and select all the text shown in the shell, copy and paste it here.
