Mount errors after restart on Jail

[TW1920]

Hello,
I'm using Plex on my FreeNAS - it worked well to my last restart of the NAS.

I mounted some Datasets on the jail (with command line on the jail) - it looks like the jail configuration have saved it but I get now these error starting the jail:

Code:

The above exception was the direct cause of the following exception:

On the NAS I can access to /mnt/Storage_100101_z2cl/Dataset_100101_Media/Filme without any problem. So I looked to "Mount Points" of my Plex Jail - there are the Mount for "Filme" exists on 3 lines. Two like on the error message, on the other one the destination is "/mnt/Filme" - there was my mount point before restart. Why I have now 3 entries for one mount and 2 of them to the wrong destination?

Adding the mount again would be no problem, so my plan was to delete the mount points, but doing this I get this error:

How can I delete the wrong Mount Points?
Now I know it's not good to mount something on a jail, but I have no plan I can fix that. Searching for that I couldn't find something useful.

Thanks

The NameError was a bug that is fixed for U3 (due out this week): https://redmine.ixsystems.com/issues/77305. Note #9 in that ticket has a workaround until U3 is available.
