How to access data of Datasets from lxc container Instances

[KBB]

Right now I started the Migration process from CORE to Scale.

I installed TrueNAS Scale from scratch and imported the Pools.

I had a Nextcloud jail with connected Datasets.
Now I want to keep that structure

SSDTank->Instances->Container->ContainerName

I know that Instances is still in experimental.
My question is how can I add and access the datasets?
Right now I gave them the 777 permissions to write to them.

I created a user nextcloud UID 3000 with primary group on TrueNAS Scale and then created it with the same UID in the lxc container and added root to that group.

Additionally I mapped the User and Group

But when I change the permissions on TrueNAS Scale to 770 I can’t access the data.

Best case would be to structure it like:

SSDTank->Instances->Container->Nextcloud mounted /root
SSDTank->Instances->Container->Nextcloud->config mounted /locationNextcloud/config
SSDTank->Instances->Container->Nextcloud->db mounted /var/db/mysql
SSDTank->Instances->Container->Nextcloud->themes mounted /locationNextcloud/themes
Tank->Nextcloud_Data mounted /mnt/data

I also added them in the Instance Screen:

Add them as a “disk” to the LXC. Like this:

Ok I found the Problem I needed to restart my container to fix the permission I guess a reload of fstab would also be enough.

I already added them this way:
