Nextcloud Univention

I’m running nextcloud on univention. The installation storage datafiles in root or base-directory. Now I have mounted an external drive and want to change the storagedirectory to this. Is there anybody to help me, doing it step by step?

have you put your question on ucs-forums, already?

No. I’ll make it soon.

other than that the only things that i know are: it seems to be implemented by docker technology… and you’re gonna find some hints here on the forum on how to setup a docker with an “external” storage…
but i dunno how to implement that under ucs.
