I just started having this problem not to long ago, usually I'd just restart and things would be fine for a while. So tonight I got bored and started looking into what was going on.... I'll try to be thorough here...
I tried create a shared folder named "Test" and get this error.
Code
Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; systemctl restart 'sharedfolders-Containers.mount' 2>&1' with exit code '1': Job for sharedfolders-Containers.mount failed. See "systemctl status sharedfolders-Containers.mount" and "journalctl -xe" for details.output of systemctl status sharedfolders-Containers.mount

Obviously "Containers" is where I store my docker containers on one of my storage drives. I go to a command prompt and stop all my docker services w/o error...

root@openmediavault:~#I can then create/delete folders under the shared folders section w/o issue. In this case, I just created a folder called 'Test' and then restarted all docker services w/o error (same as above, just everything is starting instead).
Now I try to delete 'Test', and I get the exact same errors... I stop all docker services, and can delete the share, add a new share, etc. Then I restart docker from the command line.
I don't think I've set up anything wrong, and I never noticed this problem before... so I'm not really sure what is going on here.
