October 22, 20232 yr Dear Community, I ran in some kind of issue here which I am not able to solve. After a reboot auf the system my cache is unmountable. I ran a check on the disk which came back ok. I tired to follow this Guide from the faq. But got stuck as the disks are still not mounted. https://legacy.wiki.unraid.net/Manual/Storage_Management#Checking_a_File_System I uploaded a picture of what the UI is showing: https://imgur.com/pWYscvs Kind regards for your help storage-diagnostics-20231022-1446.zip

October 22, 20232 yr Solution I've never seen that error before, but it looks fatal, see if here for some recovery options, if one works best to backup and re-create the pool.
October 22, 20232 yr Author Thanks for the information running the backup right now. I was able to mount one drive with this command from the link. mount -o rescue=all,ro /dev/sdX1 /temp had to change the drive. I think I can recover all the data. Thanks for the confirmation.
