@MainrtNr5 Thanks for the update and glad your up and running again.
Yes, we really need to get on that Web-UI warning about rock-ons root snapshots actually being the docker images that back the rock-ons. But all in good time and I’m a little reluctant to add it to our Rockstor 4 milestone given it’s more an enhancement than a fix in the context of what we have there already.
On this note, and given our Rockstor 4 is well on it’s way to final release:
you might be interested in testing out our current/future state as it were:
Your Stable subscription is equally valid there, it’s just that we as-yet only have a 4.0.4 rpm placeholder in the Stable channel until we are happy we have feature parity with our now legacy CentOS base. But the outstanding issues to date are some Web-UI logging and AD/LDAP stuff that may not be of concern to you in your test-bed setup. Plus if you do find any issues we can act upon them, where as, due a combination of CentOS being an older base and some of our own intrenched technical dept (I’m working on that 
) we are no longer releasing for the CentOS variant anyway.
Another advantage of the ‘Built on openSUSE’ Rockstor 4 variant is the years newer, and upstream supported, btrfs stack. This puts us on a far more solid and timely btrfs base. Something we failed to achieve maintenance-wise in our older CentOS variant.
Thanks again for the report and if you fancy jumping on the current/future 4 releases do let us know if you have any issues. And Thanks also for helping to support Rocksor’s development: much appreciated.
Hope that helps.
