Adding more drives and unofficial upgrade to OS 6
I'm looking to do the unofficial upgrade from 4.2.31 to OS 6 and also add additional drives (I currently have 2 and want to replace them with larger ones and add an additional 2 so I can have dual re...
The disks will be re-formatted and the RAID array completely rebuilt as part of the conversion process. Installing the new disks first will just take more time, and won't bring you any benefit.
I'd start by powering down and removing your two current disks. Label them by slot, just in case. Then put one of the larger disks into the NAS (blank) and power up. It will do a fresh factory install of OS 4.2, but it won't need to resync (because there is only one disk). Then do the conversion with just that disk in place.
Post conversion, there are a couple of ways to proceed. I think the fastest is to switch to flexraid, and destroy the data volume. Then insert the remaining disks, and create a new RAID-6 volume. I'd stick with the default volume name of data.
The alternative is to add two disks in XRAID, wait for resync, and then switch to FlexRaid. Then add the last disk for redundancy.
I believe you will be able to turn XRAID back on after that using either procedure - but there are some non-well understood constraints on that.
Note that with OS-6 you switch from XRAID to FlexRaid (and back) without using RAIDar - it's done from the admin web ui.
