viper81 Posted June 10, 2023 Share Posted June 10, 2023 (edited) Hello everyone! I rarely post because I usually figure out issues myself as a long-time user of Unraid. However, I'm currently facing a problem. This morning, I woke up and noticed that my dockers had frozen overnight. When I accessed the Unraid WebUI, I saw that my main Cache pool was labeled as "Unmountable" (refer to the picture). This cache pool stores the following: Appdata folder System folder I can't believe I disabled backups for it several months ago, so now it's crucial for me to see if I can recover as much as possible. I attempted to follow the steps for recovery, but I'm a bit confused at this stage. v6.10-rc1 and newer use: Link to Source mount -o rescue=all,ro /dev/sdX1 /temp For a pool: replace X with any of the devices from the pool to mount the whole pool (as long as there are no devices missing), don't forget the 1 in the end I replaced "X" with nvme0n1 My output was mount -o rescue=all,ro /dev/sdnvme0n11 /temp I then get the following output mount: /temp: special device /dev/sdnvme0n11 does not exist. dmesg(1) may have more information after failed mount system call. Any and all help would be greatly appreciated! viper-diagnostics-20230610-0924.zip Edited June 10, 2023 by viper81 Quote Link to comment

Thanks I did what you asked. You might see some dockers now in the logs. These are ones I just manually created to get my server up and running again. What's crazy is after I ran your command you gave me and rebooted the drives are back?? btrfs rescue zero-log /dev/nvme0n1p1 I started to backup and will make sure that my CA Appbackup is running again in the future. I just need to know if I need to set any CLI flags back or your recommendations? viper-diagnostics-20230611-0921.zip Edited June 11, 2023 by viper81 add picture and more text Quote Link to comment
viper81 Posted June 11, 2023 Author Share Posted June 11, 2023 I want to add that I think I recovered everything and backed up my data. I really appreciate it. I also set back up CA backup again "properly". btrfs rescue zero-log Since it worked will it exit to zero-exit status after it recovered after the backtrace was completed? I really do appreciate all your help and I had a feeling you would be the one to reply! Quote Link to comment

Not sure what you mean, just make sure backups are up to date since this error sometimes re-occurs. Quote Link to comment
