The USB drive on my server has failed, and unfortunately I do not have any backups of my old USB nor screenshots or similar of how my array was laid out. (Needless to say I will be taking care of this issue going forward). I've tried the old USB with multiple machines but it appears to be completely dead. The docs for installing Unraid on a new USB (https://docs.unraid.net/unraid-os/manual/changing-the-flash-device/) state that you need to create the new array with the same drive layout as it was before, however I do not have any records of how it was. I can make some guesses, but some of my drives are the same size and I don't know which one was the parity disc etc. The support page said to make a forum post, so here we are. Specific questions: 1) Does it matter which order the data disks are in? For all but 2 of my drives I can narrow down whether it should be Cache/Data/Parity based on the capacity, so if the order of the disks doesn't matter then this will help. 2) I have 2 disks that could be my parity drive. Is there any way at all I can tell which one it was? If I pick the wrong one, what happens? Could I just attempt to mount the drives one at a time until I get to one without a valid filesystem (because I assume the parity disk will not have one on the basis that it is "random" ones and zeros based one the other drives)? Thanks in advance for any assistance, if I'm out of luck then so be it but hopefully there is something I can try... EDIT: I've just scrolled further down that support page and see some troubleshooting I can try, apologies for creating a topic in error (assuming it works)
