Before clicking submit: Please check if your query is already addressed via the following resources:
- Official documentation (searchable and regularly updated)
- How to topics and FAQs
- Forum search
(Utilizing these existing resources is typically faster. It also helps reduce the load on our generous volunteers while elevating the signal to noise ratio of the forums otherwise arising from the same queries being posted repeatedly).
Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can. 
The Basics
Summary of the issue you are facing:
After a reboot my datadir isn’t found? I installed Nextcloud AIO on a raid 1 mounted drive and included that in the docker command:
sudo docker run \
--init \
--sig-proxy=false \
--name nextcloud-aio-mastercontainer \
--restart always \
--publish 80:80 \
--publish 8080:8080 \
--publish 8443:8443 \
--env NEXTCLOUD_DATADIR="/media/daan/a15e1c0a-dc19-4b76-8d00-f248a4739987/nextclouddata/ncdata/" \
--volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config \
--volume /var/run/docker.sock:/var/run/docker.sock:ro \
ghcr.io/nextcloud-releases/all-in-one:latest
Steps to replicate it (hint: details matter!):
On Restart I keep getting this error:
