@Baguaman Re:
Unfortunately we don’t yet have another iso out. But we have one in the works that is our “Based on openSUSE” variant but I first have to make sure we are all ‘proper’ re openSUSE / SuSE tradmarks before we can release that one. But you can install the old 3.9.1 iso and subscribe to stable and it will update the base CentOS and upgrade all the way to 3.9.2-52 (released today) on the rockstor package side. But it will take ages as there are now many hundreds of MB of downloads for all the upstream stuff, and during this upgrade the Web-UI will disappear for a bit. Just be patient and give it some time.
Let us know how it goes.
And if the latest stable doesn’t suit then our CentOS testing channel is very usable and a lot newer than the iso install, but still old unfortunately as we are now working towards our openSUSE variant. If you go the CentOS testing channel route and then update to latest CentOS Stable channel; make sure to take a note of the following forum post:
Hope that helps.
