I habe a 2 bay Synology here with a mirror raid and it needs an upgrade in size. Pondering a bit on how to:
1: remove drive 1, let it rebuild, remove drive 2, let it rebuild (Is DSM lost here?), new capacity available. Cheapest solution.
2: get two USB cases, remove drive 1 and 2, put them back in USB cases externally, put in two new ones into the NAS, plug in the USB drives and hope it finds the raid configuration again, copy to internal. Cheap solution.
3: buy a secondary 1-bay nas, copy over, upgrade old one, copy back, have an extra backup target. Expensive.
Questions:
Do I risk loosing the DSM installation if partial swapping internals?
Can an internal raid that is put into usb cases be recovered?
Thanks for any advice here.
