Craig,
We have been running VINUM here at our ISP for quite some time
now. It works great... we have our /usr and /var partitions setup on 2
different mirrored volumes. The overhead is low and access times are
great. With VINUM, if one of the mirrored disks go out, the volume should
not crash <grin>. As far as ccd goes, I have never used it, but I believe
both ccd and VINUM will not mirror a boot partition (I know VINUM won't
yet). The VINUM was difficult to install, only because I was trying to use
the port that comes with FBSD 3.1. If you go this route, I suggest
downloading the lastest version and you shouldn't have problems. Hope this
helps...
