November 13, 20241 yr Greetings, I'm an idiot - a book fell off a shelf and bent my USB disk hanging off the back of the computer. I -THOUGHT- I had myself backed up via Unraid Connect but I started up too many servers at once and this one didn't get finished, I guess. I've successfully replaced my license and moved onto a new USB stick (will move to an INTERNAL solution and back up this one ASAP) so my system is up and running. System is still pretty simple - I have 3 16TB drives for data shares, 1 20TB for parity, and 2 SSDs for cache / app / VMs. I really only care about getting my data shares back up and running right now. I can mount the three data drives with Unassigned Devices and browse using the web interface, everything appears to be intact. If I just assign the three disks to the array, will it wipe them? How do I start creating my shares from these drives again? I guess not really understanding how the sausage is made I'm a little nervous to proceed from here. I'm pretty sure I don't need to sit around copying all my data off the unassigned devices onto something else and start fresh from an empty array, right?
November 13, 20241 yr Solution Since you know for sure which drive is parity, and your pool config, you can simply reassign all the drives as they were, check the box "Parity is valid" (it's not totally valid, but pretty close) and the array should come back with all your data. Your shares are simply the root folders on all the drives, so they will come back up, with default settings. You will need to edit each one to export it via SMB and / or NFS and set users. The parity check that runs will find a few errors, hopefully not that many.

I was imagining reassigning the drives to the array and watching as it wiped them all clean. Can't wait to get up and running again!
