@jdaviescoates said in Volume disk space strangeness:
/me goes to reduce the size of the volume back to a perfectly sufficient 10 GB...
Oh, bollocks. You can't decrease the size of Hetzner Cloud Volumes, only increase them. So I'd have to create a whole new one and then and then and then...can't be bothered with all that so I guess I'll just stomach the slightly increased cost of 15 GB over 10 GB.
@jdaviescoates said in Nextcloud says 5.3GB used, Cloudron says Nextcloud is 19.16GB, why?:
That's "just" a difference of 2.66GB (which I guess could mostly be just Nextcloud files themselves)
So, assuming that is mostly just Nextcloud files themselves (I may do a clean install at some point just to see how big that is), I think this can be marked as solved.
Just leaving a note for myself, but it's unclear why the issue got fixed after the update. After an app update, the container is recreated and the collectd config is regenerated. Maybe the collectd restart did the trick.
@foliovision you can also try docker system prune -a --volumes but generally I have never succeeded in making that reclaimable space be less than 2GB in any server using docker (even without Cloudron).
