Reconnecting with my existing docker data and portainer not working

Just updated to OMV5 got issues with docker

My existing docker from OMV 4 are on an external disk /srv/dev-disk-by-label-WD_10TB_1/docker

First Portainer although is saiying installed but the installation went wrong according to the pic the web page cannot be open at myip:9000 I can only use cokpit for unknown reason .

in cokpit the dockers are running but if I open emby for example I can only rich a new generic page asking to start a new library.

How to have portainer working (Something went wrong trying to pull and start portainer ...)?

and more important how to connect the existing database to my dockers?

UPDATE

I was able to finally install portainer by leaving blank docker storage in docker page, but in this case neither portainer nor cockpit could link to my existing Docker although I made a symlink in etc

ryecoaaron do you have a hint regarding how to reconnect my existing docker with their data without rebuilding them

Zitat von ryecoaaron

Stop and remove the container. Start a new one with the volumes pointed at the correct location. This won't rebuild the image.

Portainer and OMV 5 are kind of foreign to me, also I forgot to mention my AppData folder is also on /srv/dev-disk-by-label-WD_10TB_1/ do you a simple guide how to achieve this ?
