Hey there. Been running Unraid for quite a while with far more ups than downs. However, I've run into some bumps in the past week or so. First it started out with problems with a Docker container writing continually to the log, which then filled up my docker.img. I deleted and rebuilt the docker.img, so seems like that is taken care. However, when I restarted the server I began to run into issues with a stale configuration. I've had this problem in the past, but have typically been able to fix it by rebooting until the array starts. I used the same method here (not great, I realize) and finally got the array back online. However, once I got the array started I realized my cache drive was not online any longer. I then shut down the server, rechecked all the cables, restarted the server and the cache drive was back.
What I'm running to now is my parity drive went offline last night with an error reading "Parity disk in error state (disk dsbl)". I have shut the server down, rechecked all the cables again, and then brought it back up. Stopped the array, took the parity drive out of the array, started it again, shut it down again, and then put the parity drive back in the array. At this point the parity rebuild process starts but almost immediately fails with errors. I've run SMART on the drive and it comes back fine, but things are clearly not working.
I've attached the diagnostics, happy to provide any other information that could be helpful.
