I also have the same issue installing and running Plex on my HexOS setup. Following your steps, I get an error.
[EFAULT] Failed to stop docker service: [EFAULT] Failed to umount dataset: Dataset SSDs/ix-apps not found
But I seem to get a simal issue every time my NAS reboots
Failed to configure docker for Applications: Missing "SSDs/ix-apps/docker, SSDs/ix-apps/truenas_catalog, SSDs/ix-apps/app_mounts, SSDs/ix-apps/app_configs" dataset(s) required for starting docker.

I have completely wiped my drives and reset my HexOS. I fully disconnected the drives and wiped them again, but I am still experiencing the same issues. Can anyone provide help?
