root@Crusty:~# blkdiskcard -f /dev/nvme1n1 bash: blkdiskcard: command not found Tried that and got the above? I'm just typing that in the terminal window you get to from the >_ button at the top right? Edit: I found what you meant- blkdiscard* did the rest and attached diag. looks like that worked to me! Thanks for your help with this! crusty-diagnostics-20260217-0937.zip

ok, i did that and then removed the pool, readded the pool with 1 slot and added nvme0n1, it started and seems fine. crusty-diagnostics-20260216-1523.zip

OK i believe I did that as instructed. even though i made it 1 slot it still says its not an uninstalled nvme2? crusty-diagnostics-20260216-1107.zip

ok i did, seemingly, the same thing again, and this time it seems to have formatted the drive when i started the array. i think I'm good to go. gonna post diagnostics again if you could check if everything is looking ok. crusty-diagnostics-20260212-1634.zip

ok, I got the ssd onto a windows machine, deleted the volume in disk management and recreated a new NTFS volume. I installed it into the server and Its now showing up as mountable. my problem now is I'm not sure how to make unraid reformat the drive to use BTRFS so i can add it to my cache? screenshot+diag attached crusty-diagnostics-20260212-1612.zip

it shows in windows disk management, but the only option i have is to delete the partition on it. maybe ill try reformatting? or maybe try to upgrade firmware? I have it on a usb m.2 adapter. Sandisk/WD's own dashboard software can't find it. I'm gonna see if I can get sandisk to help/replace

I took the drive that wasn't working and swapped it to a 3rd m.2 port on my mobo. still not showing. (the other drive is under some "ssd armor" under the cpu heatsink, would be a pain to get to) i double checked that the new m.2 slot's lanes aren't being used for other sata ports. I'm gonna take the drive out and see if i can see it in windows i guess. new diag attached crusty-diagnostics-20260212-1240.zip

ok, I was able to shutdown the machine and bring it back up(even left it unplugged for a bit). still showing as unmountable. Luckily the drive is still under warranty so if its dead hopefully i can get it replaced.

I gave that a try. still not showing. I'm not gonna be physically at its location to try a complete power cycle for a few days, but I did reboot. it shows as unassigned but unmountable. I guess that means its just dead? Fun time for a 2TB drive to die lol

started with a dockerimage corruption. noticed BTRFS errors on my BTRFS NVME cache pool. while the array was running it showed both as green. when i stopped the array (after moving everything off the cache to change to ZFS) it showed my second NVME drive as no device. I also notice its showing up in the unassaigned devices. If its can see teh device, why isn't it able to be used in the pool? Not sure if it means my drive is dead or just the filesytem got corrupted and its not sure what to do with it? Like i said, no data is on the pool. suggestions to move forward? attached current Diagnostics and when i pulled diagnostics after the dockerimage corruption. crusty-diagnostics-20260205-1542.zip crusty-diagnostics-20260203-0904.zip

Last time I was in the case was when the HBA dropped a different drive. It was been closed for 20+ days before this happened.

I'm fairly certain its the HBA. Never had an issue with a drive and suddenly two after installing the HBA. Thank you for your help! Sending a coffee your way!

Thats really weird... The files that went missing from plex aren't even on disk 5... thats scary.. New Diag. I'll own you a couple coffees thanks JorgeB for helping me. After the reboot the other files seemed to come back into plex.... They share an HBA card. an evidently low quality one that i will replace as soon as the new one arrives. On the same power supply but not on the same line crusty-diagnostics-20250108-0951.zip

posted above also seeing missing files in plex that weren't missing before I checked Sonarr logs and a BUNCH of stuff suddenly couldn't be found at 10:06:56 PM (eastern) I don't see any other drive thats failed? That's WELL after I noticed this issue so idk what thats about.
