Hi, I have been running my server for almost 2 years with no issues, tonight I was having an issue where my server log file was filling up  

 

       

 

                                                                             so I rebooted the server, when it came back up the second cache drive was missing completely from the system, like I never even had it in there.

I tried reseating the connectors and even tried other connectors from a different drive and it still wouldn't show up, so I tried reducing the cache pool back to 1 drive until I can order a replacement drive. When I tried bringing the array online the remaining cache drive would not mount, it was giving me the "unmountable : not mounted" error, so I went to the drive and checked the BTRFS file system check in read only mode                                                    I also went to the drive and took a capture of the disk log itself                                                                         I connected the "bad" drive to my computer and it shows up in disk management so I am unsure if it is actually bad or not. What can I do from here? I want to try to recover the file system if at all possible, any help is greatly appreciated.

Because the other device is missing Unraid is not trying to mount the pool degraded (assuming it's raid1), you can do that manually, if successful backup pool contents and re-create the pool after replacing cables on the device that caused issues before.

I will give this a shot!

This did the trick, thank you for the help!
