Sorry for the slow reply… the work trip turned into more work and I haven’t had any me-time to explore this further yet. I really appreciate the share of the Synology settings. Those are in line with what I’m set up as too, unfortunately.
Good tip on the immutable volume config too. I was not aware of that or taking it into consideration when I was adjusting settings on the NAS to try and solve this. Just tried dropping and rebuilding one of the vols just now but it the containers still didn’t start.
On the hostname/IP, I use IPs for the share. 4 of my 6 that are failing I have set up on their own VLAN (each of which are also set up in Docker as macvlans and work fine). The other 2 are running on the host IP. I appear to have both the docker host ip & respective container ip permissioned in the NFS shares on the NAS and the 4’th one (interestingly) only to the Docker host ip.
Not sure when it will be, but I do have another box here that I can start fresh on with the sole intention of getting one @$%^@ container to start up on its own.
Again, I really appreciate the validation that it at least SHOULD work and I haven’t been trying to do something impossible!!
