@koskee Welcome to the Rockstor community.
I can chip in on this one:
It’s not currently available as a downloadable installer but the following repo has directions on building your own installer:
and note that there is also a vagrant/virtual-box orientated method available in a subdirectory of that repo that may be more accessible:
rockstor-installer/vagrant_env at master · rockstor/rockstor-installer · GitHub
And once you have the installer you can do a fresh install, ideally to another system drive with no other drives attached. And then once you are happy it boots you can attache you old data pool members and import the pool:
Import BTRFS Pool: http://rockstor.com/docs/disks.html#import-btrfs-pool
You can also use the config backup-restore between the variants, as long as you download-upload the config file:
Configuration Backup and Restore: http://rockstor.com/docs/config_backup/config_backup.html
But as always it’s best to have a reliable tested backup before doing anything like this.
And as for the new install itself we have the following guide which covers every step of the new install process:
Rockstor’s “Built on openSUSE” installer - Beta release

Re:
Not required. The above DIY installer maker pre-intergrates a know good rpm version and you can then update to your preferred updates channel. Or not.
The issue here is that I think the default kernel in openSUSE Leap 15.2, our new base employed in Rockstor 4, also doesn’t yet include this newer raid level. Also Rockstor itself doesn’t yet cater for the > 2 copies of raid1 variant either. I’m actually not sure how it will react either. But we definitely intend to add these newer profiles. A third concern here is that if you btrfs subvolume arrangement is not known / recognised by Rockstor then it will not be recognised by Rockstor. At least in the sense of subvols recognised anyway.
Thanks, yes we were having a number of looming and actaul issues with the CentOS variant, hence the ‘Built on openSUSE’ effort. In the end we couldn’t even build the rpms on CentOS hence our final Stable channel release on that OS being 3.9.2-57, but we are now on 4.0.5 for the Leap 15.2 rpms:
OK, haven’t heard of that one before.
That sounds like a likely candidate. But still shouldn’t happen.
Yes, very annoying.
I would suggest, given your obvious patience/perseverance that you strongly consider the Rockstor 4 DIY installer build route. I know it’s a nuke and pave option. But if you do have issues there then at least we can try and fix them if they originate in the Rockstor code. Plus you will be that bit closer to a newer kernel for your exotic raid levels: which you seem to be managing as-is anyway. Also when we do properly manage those raid levels you can help with our treatment of them.
I say have a go at making the Rockstor 4 installer and if all does not turn out rosy within your patience/perseverance limits then post the exact issue you are experiencing here on the forum, ideally in a new thread. That way the growing number of forum members who have managed to build the installer can chip in and steer you right. Plus it will help us see where our docs are lacking on this procedure as I’d really like for it to be as accessible as possible.
Apologies for offering only a work around here, but our development effort is now sole focused on the ‘Built on openSUSE’ 4 variant and in that regard it would be easier to help you going forward anyway.
Hope that helps.
