Check the handbook's hardware listing (http://www.freebsd.org/handbook/install.html#INSTALL-HW) for a list of supported SCSI RAID cards. Another idea is ccd. Check "man 4 ccd" for details about it. If I recall correctly, you'll have to compile the ccd driver into the kernel and then do a bunch of configuring. This should let you make several partitions become one continuous disk. (In other words, two 1GB partions become a 2GB virtual partion.) The third idea is vinum. Check "man 8 vinum" for details about that. Again, I think that you need to compile it into the kernel. The main benefit of vinum over ccd is that it allows configurations which act like software controlled RAID-5 arrays. Support for vinum (especially its RAID-5) is supposed to be much better in FreeBSD 3.4 than in 3.2. If you go this route, look into using cvsup to upgrade your installation. (I've used this to go from 2.2.5 to 2.2.8 and 3.0 to 3.2 in the past without any real problems. Going from 2.2.8 to 3.0 turned out to be impossible at my skill level, though. Be careful to read everything and make backups before using cvsup!) Good luck, Jaime To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
