The HP was a brand new installation, and one of the mirrored drives failed (Less than a week of use) and the application absolutely could not tell there was a failure. I didn't find out about it till I checked the system console. So, I would be interested in developing some sort of mirroring/logical volume capability for FreeBSD. I feel that this would lend a lot of credit to FreeBSD as a "commercial" product, and perhaps make it a more acceptable replacement for commercial Unix systems to people that may be reluctant to use a freeware product. I am an experienced C/Unix person, but have never gotten my feet wet in the kernel, so I would need some mentoring. Still I think I could pull this off with a little help. If anyone else is interested in pursuing this please email me. Some words of encouragement from an experienced file system person would be especially welcome. Ron Steele rjs@clark.net
