August 7, 20232 yr This seems to be an ongoing issue, whenever I try to stop the Array, I get this repeating in the log... Aug 7 12:49:52 Gandalf root: cannot unmount '/mnt/cache/system': pool or dataset is busy Aug 7 12:49:52 Gandalf emhttpd: shcmd (336): exit status: 1 Aug 7 12:49:52 Gandalf emhttpd: Retry unmounting disk share(s)... This also results in a Parity Check after every reboot. I've seen others with the issue solve it by updating to the latest version, but I'm already on the latest version. Any ideas?

Docker is not unmounting, not sure why, if you stop the docker service first does it unmount?

August 7, 20232 yr Community Expert Please retest after booting in safe mode to rule out any plugin or extra packages issues.

August 8, 20232 yr Community Expert Possibly there was something else preventing /var/lib/docker from unmounting, like an opened ssh session for example.
