RN10400 HDD Upgrade
Hi there,
Basically I want to find out how to upgrade my 4 x 2gb HDD to 4 x 4gb HDD. I can swap the drives over but will it automatically recognise the new drives and size of them? Or do I have to swap them over in a special way? I have copied all the backups on the drives so starting again with blank drives is not a problem.
Many thanks for any help.

- You can replace the disks one by one. You should check the SMART stats first and replace the least healthy disk first. If all disks are equally healthy then you can replace whichever disk you feel like first. Wait for the resync to complete before replacing the next disk. You’d need to have replaced at least two disks before you’d get vertical expansion as expansion can only happen when redundant space can be added. Replacing disks this way your old removed disks would be useless for recovering data from your data volume as they’d be out of sync with one another.
However you would probably find that powering down, removing all your old disks (label order), put all the new disks in, power on, restore from backup would be much quicker. An advantage of this method is that you’d have a single layer array which would mean a little better performance and is easier in the unlikely event a data recovery attempt is needed. Furthermore you could keep the old disks for a while in case you need to get the data off them.
