UCS 4.2-3 OwnCloud 10.0.3.3 move data folder problem

Hi,
im currently facing the same issue that i want to change my ownCloud data directory but without any success so far,

dmitry, thx for your support but your proposed solutions to install owncloud in a dedicated VM or the instructions in the provided link are not working for me.

Im on UCS 4.3 with onwCloud 10 and what i’d like to achive is that ownCloud is using an allready exisiting cifs-mount (/mnt/owncloud) as the data directory. All of my approaches to realize that were not successful so far (e.g. set UCR variable for the data directory, edit config,php, copy data to target mount and set softlink). My feeling is that changing the OC data directory became a bit more tricky as it is running in a docker container now.

Any support/instructions on this topic would be much appreciated!
