Hello Volker,
This is an area where improvements should be made. The bugs have existed for a while.
For the file systems, the % must be there after the number. Would be really great if you could fix that.
This would be if feasible, also times to fix ...
Thanks
P.S. Once from my place a big praise for the good OpenSource project OMV - Is everything not self-evident in the time, go on so Volker!
