November 29, 20214 yr Hello unraid community, I hope someone in here has an advice or even a solution to my "problem". I replaced my USB flash drive today. However, I did not realize that I generated my new USB flash drive with an old backup (Oct 21). I have downloaded the backup zip file via the my server plugin, but now I notice that this file has a timestamp of october 21. The unraid server is now running again and the license could be activated. However, the disk layout is no longer correct (since the backup date I have added a disk to the array and replaced my SSD cache disk). The missing array disk and the missing cache disk are now showing up as unassigned devices. In theory, the data should still exist on these disks (didn't touched them). Is it possible to add the drives again without formatting them? And/or can I somehow recover the appdata files from my "unassigned cache" drive? In theory I still have my cache disk (at least the data), it's just an unassigned disk now. The same applies to the array disk, where all data should also still exist. I hope there is at least a way to "get back" my cache disk (installed and changed quite a few dockers in the last 1.5 months).
November 29, 20214 yr Community Expert Have you started the array with the incorrect disk assignments? Tools - New Config will let you assign any disks however you want, and it will accept those disks just as they are with whatever contents they have. It also (by default) rebuilds parity. You can check the box saying parity is already valid, provided you never started the array with the incorrect disk assignments. If you did start, then you will have to allow it to rebuild parity.
November 29, 20214 yr Author Thanks for the reply! The partiy is now re-building and my dockers are back and working (from what i can tell so far). Some docker icons are missing tho, but maybe that can be fixed with a reboot or "force update". And a few plugins are missig, but thats no big deal.
