Just like the title says, occasionally, the docker service will "fail to start" even though it was already started and was working fine, then randomly, the service will fail crashing all applications. The array will then proceed to go offline (even though its still running??? and says its its running mover/parity sync.) no data on the array is lost. This results in basic functions of the server environment to fail. Your unable to load parts of the GUI related to Docker, the system is unable to "stop the array" meaning that a normal reboot command (both in GUI and CMD fail to execute.) powerdown ; Docker.img runs on a M.2 SSD ZFS Cache i have uninstalled and reinstalled containers multiple times by this point. i have attempted multiple repairs of the img files. i have made new img files. the only "fix" has been echo 1 > /proc/sys/kernel/sysrq echo b > /proc/sysrq-trigger this kills the server like holding the power button for 10 seconds. thus rebooting from a clean slate. My theory's, 1: Next cloud AIO corrupts the img file and results in failure of the docker service. (transitioning to a new self hosted provider now) 2: the Jellyfin container corrupts the .img file and results in the failure of the docker service (jellyfin is here becuase when the app backup plugin runs it can never verify the backup...) 3: RAM is bad (this was a windows machine prior to being a Unraid server. Ram showed no issues when running on windows 11. ) 4: Server side bug with hardware configuration (maybe an update will help?) 5: Preserve user defined networks: Yes (is this the root cause?) system specs.
