Add extra partition for storage

[gozen]

I know I most probably miss something easy (or at least that's my believe) but seems I can't achieve what I need.

We have a DA server with SSD and we need to add an extra drive for storage let's say for a nexcloud installation.
We mount the drive under /data but nexcloud can't write to it no matter what the folder owner or permissions.

Any idea?

check mount options in fstab, mount new partition with same options as /home or / (root) partition
