From FreeBSD 6.2-RELEASE-p8 to 7.0-BETA2 and back to 6.X
…all in one night babe…
heeheh I am laffing very much just for reading this title 
, don’t get mad, don’t get impressed. I do love FreeBSD 7.0 and it sugar
What I am talking about it has append last friday night. I was installing a new “big storage server” named IRONMAN <- (wtf!) 
, with FreeBSD 7.0-BETA2 and after installing it, building it’s world and kernel, I put it in a gmirror (well just 2 of it 8 hard drives), because the other 6 are(were) for (wana guess?), ZFS… but… at 4am, I got a Kernel PANIC. Me stressed because the situation, and mad because this is not my way to do things, I just did it . I took the 6.2-RELEASE CD and installed everything from scratch and the peace of mind and spirit came to me again Yes folks its hard as a rock, its stable as a humm (something super stable here), and it’s working as a swiss watch .
Regarding ZFS well maybe in December I update this server.
