August 29, 20232 yr My cache is listed as "CacheSPCC_M.2_PCIe_SSD_AA230619NV02KG00385 - 2 TB (nvme0n1)47 C000autoUnmountable: Unsupported or no file system". There is a walkaround from 2018, is it still good ? I have a backup of my 2-3 days older of my appdata. So I could do a restore if I wipe the device. Is that the best and simplest way ? Will the issue be back eventually ? I don't know what happened, I was away for the weekend and at some point my apps on my phone were not working and when I looked remotely, the server was on but there was no docker running, only the VMs. Back home, I tought there was an issue with the docker service, may be due to an update. I update the my plugins and containers on sunday to monday night, because I am usually home at that time and in case there is an issue I can resolve the next day. I only came back on monday evening. Also, my syslog was on the cache, so I don't know when or why it happened. Based on another topic : cache-become-unmountable-after-reboot I might have a similar issue. In the past, I had two smaller device that I replaced with a single larger one (the one I have issue with). But creating a new cache pool and assigned it to it didn't work. This is part of the log of the device.

August 29, 20232 yr Author 3 hours ago, JorgeB said: Please post the diagnostics. Of course. I don't have the logs has it was on the cache. But here is the diagnostics. Is the simplest way to remove the cache, create a new ones (with a new name), format the nvme and add it to it and do a backup restaure with the app-backup tools ? servername-diagnostics-20230829-0825.zip

August 30, 20232 yr Community Expert I'm just trying to see if a partition signature exists, in case the partition was wiped with wipefs with would, but it doesn't since Unraid only uses 64 as the starting sector for older releases, 2048 for newer, so looks like the device was fully trimmed/delete/wiped, and don't see how to recover any data, you can still try something like testdisk to see if a partition is found or UFS explorer, then reformat the device.

I will reformat and use the backup, there shouldn't be much change. What I am wondering is why and mostly how it happened. Don't want that to happen again :s.
August 30, 20232 yr Author I formated the nvme drive and unraid failed. I had no gui and couldn't ssh. I waited but nothing happened. So I turned the server off and rebooted. Now the nvme isn't listed. I don't even see it on my bios. Not sure if there is a fall back or if it's the drive that is faulty. I might try another nvme to see if it's the drive or the motherboard or something else.
August 30, 20232 yr Community Expert Try a power cycle instead of a reboot to see if it comes back online.

August 30, 20232 yr Author I installed another older nvme and it get recognized as unsassigned. I reinstalled the nvme that is faulty and I don't even see it in unraid.
