May 4, 20242 yr Hi i recently replaced one of my Parity drives. the server booted fine and was able to start the parity rebuild. a couple hours later i logged in and there was a flash drive error. i waited a couple days to try rebooting so the parity rebuild could finish. i was still able to use my docker apps during this time but could no longer login to the GUI or Console. I did do a backup of the flash drive recently but stupidly never copied it off the server. Is there a way to plug each drive into a SATA dock to find the backup? thanks in advance

May 4, 20242 yr Author Thanks for the post. I was able to boot up using a new flash drive and transferred the key. i do know the disk assignments prior to the flash drive crashing. there are two things that i'm worried about. 1. there is currently a message next to the parity drives saying they will be overwritten when the array is started. does this just mean as long as the data drives are assigned correctly it should just rebuild the parity drives off of them and everything will be fine? 2. my cache drives in the old config due to a previous cash drive failure were labeled cache 2 and cache 3. in the new setup they are cache and cache 2. will the data on these drive be erased if they are named different than they were previously? would it just be easier to pull the data drives and try to find the old flash backup and copy everything but the super.dat since the drive configuration has changed since the last backup? thank you for your help!

Yes, but if all the assignments are as before, you can check parity is already valid to avoid the sync, though would then recommend running a parity check to confirm all is well. 16 hours ago, MikeMercer77 said: 2. my cache drives in the old config due to a previous cash drive failure were labeled cache 2 and cache 3. in the new setup they are cache and cache 2. will the data on these drive be erased if they are named different than they were previously? It should import the old pool, if it doesn't post diags after start.
