Summary of the issue:
Got Nextcloud setup on my DNS domain. Trying to mount user directories from my Nextcloud install to my DAS without shipping the entire installation over so it can run on my mini pc SSD.
The Nextcloud External Storage UI app has some apparently reported bug in it. It honestly doesn’t appear to mount other directories from what I have seen reported and tried. Also cannot use symlinks instead of bind mounts. Usins only for 3 accounts.
I am debating recreating the whole Nextcloud installation as I have documented my own for ease of setup.
I have not had any success with mapping Nextcloud external storage to my DAS array and have noticed even though I am using AIO I can see in the Nextcloud Docker Github README:
Custom Data directory (datadirectory)
If you don’t want to use the default data directory (datadirectory) location, you can set a custom one:
NEXTCLOUD_DATA_DIR (default: /var/www/html/data)
Configures the data directory where nextcloud stores all files from the users.
I notice that is different to what is mentioned in AIO README:
By default, the Nextcloud container is confined and cannot access directories on the host OS. You might want to change this when you are planning to use local external storage in Nextcloud to store some files outside the data directory and can do so by adding the environmental variable NEXTCLOUD_MOUNT to the docker run command of the mastercontainer
As I have not made any progress, I am wondering if I should Borgbackup in the server UI and reinstall from scratch as per this github answer about Changing the data directory?
Steps to replicate:
-
Create
/mnt/md1/ncdata/Jordan Nash/fileson your DAS or whatever. -
You will see these permissions:
ls -ld "/mnt/md1/ncdata/Jordan Nash/files"drwxr-xr-x 7 www-data www-data 4096 Apr 17 07:33 '/mnt/md1/ncdata/Jordan Nash/files' -
Instead of using the UI use CLI like this and get these outputs:
docker exec -it nextcloud-aio-nextcloud php occ files_external:create "Jordan's Files" local null::null -c datadir="/mnt/md1/ncdata/Jordan Nash/files" There are no commands defined in the "files_external" namespace. docker exec -it nextcloud-aio-nextcloud php occ app:enable files_external files_external 1.24.1 enabled docker exec -it nextcloud-aio-nextcloud php occ files_external:create "Jordan's Files" local null::null -c datadir="/mnt/md1/ncdata/Jordan Nash/files" Storage created with id 7 -
Use symbolic links:
sudo ln -s "/mnt/md1/ncdata/Jordan Nash/files" "/mnt/md1/ncdata/Jordan Nash/Shared-Files" -
Logging into the UI and going to that Shared-FIles folder shows me nothing and uploading files to it also does nothing on the RAID array I setup for it as per that
ncdatafolder.

Initial startup of Nextcloud All-in-One complete!
You should be able to open the Nextcloud AIO Interface now on port 8080 of this server!
E.g. https://internal.ip.of.this.server:8080
⚠️ Important: do always use an ip-address if you access this port and not a domain as HSTS might block access to it later!
If your server has port 80 and 8443 open and you point a domain to your server, you can get a valid certificate automatically by opening the Nextcloud AIO Interface via:
