By the way, when are you going to come to a BSD conference and talk about running HN? We love "view from the trenches" talks, and I'm sure Arc makes things interesting in unusual ways.
- dang 10y agoIt would be a boring talk. It just works and that's about it. Arc does make things interesting in unusual ways, but not on an OS level.
- kogir 10y agoBack when HN was still running with millions of files in one directory on UFS, maybe there was something to talk about (not much more than sysctl tweaks). Oh, and UFS snapshots (for tarsnap to reference) sometimes panic'd the box. When I left we'd added nginx in a jail and switched to ZFS, which solved most of the problems we had been having. There were a few ZFS deadlocks, but I never got to the bottom of it and FreeBSD 10 seemed to fix them. I'd imagine things are even less notable now.
- cperciva 10y agoUFS snapshots (for tarsnap to reference) sometimes panic'd the box. Ick. Yeah, UFS snapshots had issues for a while... had I known you were using them I would have encouraged you to switch to ZFS sooner. There were a few ZFS deadlocks, but I never got to the bottom of it and FreeBSD 10 seemed to fix them. Yes, FreeBSD 10 definitely fixed a bunch of ZFS deadlocks.
