root@SERVER:~# btrfs rescue zero-log /dev/nvme0n1p1 Clearing log on /dev/nvme0n1p1, previous log_root 1167934586880, level 0 After restarting the array everything is working again. Thank you very, very much @JorgeB

Ok, sadly no luck. I restarted the host just to be sure but still the same error. Attached find a new diagnostic. Thank you for your time and effort, I really apreciate the help! server-diagnostics-20240113-1955.zip

Just did the steps and this is the result for btrfs fi show: root@SERVER:~# btrfs fi show Label: none uuid: 7c22b33e-a8c5-4fe7-9852-d3fa69fd4aed Total devices 1 FS bytes used 787.69GiB devid 1 size 1.82TiB used 883.02GiB path /dev/md1p1 Label: none uuid: 912de6db-b116-4e8f-b947-5cde535b860c Total devices 2 FS bytes used 276.66GiB devid 1 size 931.51GiB used 489.01GiB path /dev/nvme0n1p1 devid 2 size 931.51GiB used 489.01GiB path /dev/nvme1n1p1 I will re-start the array now

I already tried: Stop Array -> Remove Cache Devices -> Start Array -> Stop Array -> Re-Add Cache Drives with Filesystem "auto". I also tried to manually chanche the FS to zfs and btrfs resulting in the same error.

Hi guys, normally I do not ask for help and prefer to read and troubleshoot by myselft but I am at a point where all related topics did not lead me to a solution: after a couple of (hardware related) forced reboots of my server the cache pool came up "Unmountable: Unsupported or no file system". Attached find my diagnostics. Help is much appreciated! server-diagnostics-20240113-1247.zip
