This post has been replaced by a newer one. For reference, the previous post on this server is still available. For future reference, this is the slocum server, which I use for various jails and services. This data was gathered adding increasing the RAM from 16GB to 32GB and adding two SSD to the previous […]
I have this server (I don’t actually have it; I haven’t seen it since 2006) which has started to be restrictive in what I can do with it. It’s running FreeBSD 9.2 and I’d love to start making more use of jails and ZFS. The server has 8x 50G Raptor drives, all on a 3Ware

I woke up to this today. Complicating the matter: this server is destined to be transported tomorrow morning. This is FreeBSD 8.2 I guess the good news is: But wait, is that gpt/disk04-live really /dev/ada5? Yes. Yes it is: After a question from Peter Wemm on Twitter, I added: Full smartctl output follows:

I ran a few tests recently and found some interesting results. I haven’t published them here yet. My main test is a database load.
