Help--- I screwed up while trying to add external storage

In brief, I tried to follow the instruction on “how to allow the Nextcloud container to access directories on the host” from this link:

but instead of removing the mastercontainer, I removed the nextcloud-aio-nextcloud container. Shame on me!

so I then removed the mastercontainer, added the environment required to access external drive, and tried to redo the mastercontainer but it is failing now with this error in the log:

+ '[' -f /dev-dri-group-was-added ']'
++ find /dev -maxdepth 1 -mindepth 1 -name dri
+ '[' -n '' ']'
+ set +x
Configuring Redis as session handler...
Appdata is not present. Did you maybe change the datadir after the initial Nextcloud installation? This is not supported!
If you adjusted the datadir to be located on an external drive, make sure that the drive is still mounted!
In the datadir was found:
total 8
drwxr-x--- 2 www-data root 4096 Mar  6 10:07 .
drwxr-xr-x 1 root     root 4096 Mar  6 10:06 ..

But I did not want to change the datadir (if I did). I only added an external drive.

My docker run command was:

sudo docker run
–name nextcloud-aio-mastercontainer
–restart always
–publish 80:80
–publish 8080:8080
–publish 8443:8443
–volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config
–volume /var/run/docker.sock:/var/run/docker.sock:ro
–env NEXTCLOUD_DATADIR=“/USBdrive/nextcloud”

I understood that I needed to add these 2 lines to be able to access the external drive:
–env NEXTCLOUD_MOUNT=“/mnt/”
–env NEXTCLOUD_MOUNT=“/media/” \

How can I correct my screw up?

ok, I used the AIO restore. That brought me to the state without the external drive. Then I redid what I was trying to do in the first place, and it worked.

Now I have the LOCAL choice in the External storage, but somehow, I can’t have access to it. I see a red exclamation mark when I try to set it. Searching… It’s probably some rights…

Hi, if you read further on it says what kind of rights it needs

Hi, thanks for responding. Yes this is the instructions I followed… See my result here:
