had a 2.x build with 3TB single disk plus 2+2TB RAID 1 mirror storage + OS disk....
tried the cli upgrade, no plug ins, still went badly, thru up a lot of errors with end result no GUI at the end and CLI would not let me in.
so took the advice and went with a clean install..
Pulled SATA cables from all 3 storage disks (marked them first)
Reinstalled as 3.x, same hardware..all good.
Added single 3TB disk, create FS (Ext4), added Shared Folder and SMB Share and User and all fine..
Problem is with RAID1 disks when I reconnected them.
I can see old RAID1 disks in Physical Disks page - they are plugged in identically as previous.
I cannot see any disks (aka 'devices' in gui) to select in RAID Mgt page when Creating an array
I can see and select either of the two old RAID1 disks in the File System page - but of course selecting, say, EXT4, would blow my data - according to the 'do you really want to format......' warning popup......nope!. selecting any other filesystem at the drop down gives same warning....
Is there a way to reinstate the array in the newly built 3.x environment please?
Any assistance would be appreciated..
