I’ve not tried it but have been keep tabs.
The two main problems appear to still be ongoing PRs/issues; magazine/community sidebar content doesn’t update and doesn’t federate out at all to lemmy, and moderation actions don’t federate at all (any of the various types) - which is particularly problematic.
It’s the multiple volumes that are throwing it.
You want to mount the drive at
/media/HDD1:/media
or something like that and configure Radarr to use/media/movies
and/media/downloads
as it’s storage locations.Hardlinks only work on the same volume, which technically they are, but the environment inside the container has no way of knowing that.
