AIO is mounting extra volumes in nextcloud-aio-database container

Author: mrbuckwheetCreated May 18, 2026Updated Jun 17, 2026
Labels1. to developbughelp wantedneeds info

Steps to reproduce

  1. run and deploy AIO compose file
  2. check volumes linked to nextcloud-aio-database via portainer

Expected behavior

there should only be one volume "nextcloud-aio-database" mounted at /var/lib/postgresql/data this

Actual behavior

there are two volumes: nextcloud-aio-database path in container is /var/lib/postgresql/data d3e02aa5678b469ec2b3c6cdab5c4faa637d508dcb434621a6e9046f9477fc03 path in container is /var/lib/postgresql

Other information

Host OS

Qnap QTS 5.2.9 with container station v.3.1.2 and portainer 2.39.2 (portainer is running as root via SSH install on qnap)

Trying to fix docker.sock permissions internally...
Adding internal www-data to group root
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:
https://your-domain-that-points-to-this-server.tld:8443
