Great info, Kalin. I have several boxes with LSI controllers, the PERC 5i works wonderfully with FreeBSD (though the Dell 6850 sucks), and I have a couple boxes with Supermicro boards with built-in LSI MegaRaid, however it's done in software. This means that the mfi controller works fine as individual disks, but will not support any RAID levels in FreeBSD. You're probably almost as well off using gmirror anyway. I've started using 3ware cards again after a bit of a hiatus and they work great, and the FreeBSD support is good. My next experiment is going to be some HighPoint cards. I'm not sure at this point I wold trust them with my important data, but what's cool is they are very inexpensive cards, show up in computer stores like Fry's, and seem to have pretty decent FreeBSD support for their size. I'm going to try an 8-port in my desktop (I use it for some pretty serious MySQL work at times) soon... IMHO if the cards are decent it'd be nice to reward them for their efforts by putting some money their way. -Patrick 2008/6/11 kalin m <kalin@el.net>: > > in case somebody gets stuck as i was - here are detailed instruction and the > CORRECT ORDER in which the needed kernel modules HAVE to be loaded in order > for the megacli to work properly... > > big thanks to Christoph Schug.... > > > > Christoph Schug wrote: >> >> On Mon, Jun 02, 2008, kalin m wrote: >> >> >>> >>> thanks Vince... i didnt wanted to install the linux base because a lot >>> of kids will be running some 'cool' boards or blogs that probably have cool >>> linux holes too. but just for the hell of it and for he purpose to get to >>> the controller i did. it took a while to find the Linux_MegaCli_1.01.09.zip. >>> it's not on the freebsd site and not on the LSI site (anymore) either.. >>> anyway after a lot of rpm downloads and patching and variable changing and >>> fs mountings i get this: >>> >>> # /usr/local/sbin/megacli -adpCount >>> ERROR:Could not detect controller. >>> >>> Controller Count: 0. >>> >> >> From my experience there are some pitfalls when using the >> sysutils/linux-megacli port.
