I would like to use my 700GB HDD for Nextcloud and SMB and not my 160GB boot drive. Is it possible somehow to point these services to a different location without losing my data on Nextcloud?
Sorry if it was asked before, I’m not really a Linux expert.
Thank you for your help in advance! 
You could mount the drive as /var/lib/nethserver
It is not used for only SMB and Nextcloud, but for all data that is stored on NethServer (incuding homedirs)
Make sure to copy all data from the original /var/lib/nethserver to the 700GB drive with matching permissions.
When I try to mount a partition to /var/lib/nethserver/ibay, it says: Error mounting system-managed device /dev/sdb2: Mount source not defined.
It can mount the other partition in the nextcloud folder.
Now, I also mounted my other partition in the nextcloud folder. Before that, I copied everything to somewhere else, mounted the partition and copied them back but when I try to access the nextcloud in my browser, it can’t find the .ocdata file in the root of the data directory. I also had problems with writing permissions but I solved it by entering chown -R apache:apache /var/lib/nethserver/nexcloud
EDIT: I solved it my copying the backup of the .ocdata to /var/lib/nethserver/nextcloud
