Did quite some maintenance on burningboard.net Mastodon instance today ..
Updated servers and jails to FreeBSD 15.0-RELEASE-p5
1.
proxy_cache_path (S3 media cache) was already on a ZFS dataset with autosnapshot disabled .. But proxy_temp_path and client_body_temp_path (both nginx temp folders) weren't. Leading to extremely bloated daily ZFS snapshots for the Nginx jail. Changed those and cleaned old snapshots -> 31GB reclaimed space
2.
Cleaned up Database Snapshots and did a pg_repack on prod to reclaim deleted database pages -> 3GB reclaimed space
3.
Fixed issue with backend path over gif tunnel to Elasticsearch (6in6). Turned out to be a MSS issue (clamp-mss to 1140 on the tunnel iface solved it!)
4.
Fixed IPv6 routing issue for Prometheus Monitoring after reboot (rc.d static_routes != ipv6_static_routes)
All in all, our instance is in very good shape again :-)

On Fedora 44 Beta GNOME Edition, the file manager crashes every time I try to access my NAS. There are also frequent freezes with apps that weren’t included by default and were installed later.
Ubuntu 26.04 LTS also comes with GNOME 50, and unlike Fedora, it already includes kernel 7.0, which is great—especially for the latest hardware. This beta also seems to run more smoothly and stably than Fedora’s beta.
