Hello together,
just in case someone faces into the same problem.
After an update of OMV yesterday to 3.0.71, today I saw the above named error message, while opening the rsync tab.
The solution, I found here in the forum, to delete the section <jobs> from config.xml and lose all my rsync jobs wasn't my preferred solution.
I found out that there was a mistake in the config.xml for every old rsync job (created with OMV 2).
Within the <dest> or <src> section the folder uuid was in the wrong field.
As an example:
old:
Code
<dest>
<sharedfolderref></sharedfolderref>
<uri>33bff3fb-6b43-4c2f-84a2-34ef001b76cc</uri>
</dest>
should be:
Code
<dest>
<sharedfolderref>33bff3fb-6b43-4c2f-84a2-34ef001b76cc</sharedfolderref>
<uri></uri>
</dest>
Maybe this this will help someone.
Have fun.
