I recently had a drive fail in my server. I replaced it, but since the replacement I've had several issues with the server. Docker containers don't respond to commands from the GUI, transfer speeds are low, the server won't respond to reboot or shutdown commands, stopping the array causes the server to lock up (forcing a hard reboot), and the mover can't move files (it just runs continuously until the server is restarted via hard reboot). I'm not quite sure where to look, as none of the drives are reporting errors and Fix Common Problems isn't showing any issues. Fortunately, all of my containers and plugins seem to be working fine (as long as I don't try to stop or update them). Diagnostics is attached. I looked through it myself, but nothing stood out to me as weird except for this error in the syslog:
