We have a storagetak raid with 2 x 65 GByte RAID 5 arrays. We are going to mount both arrays under FreeBSD and then use software raid 1 (Vinum) to mirror the two raids (It's a single point of failure in a huge cluster so it's really important to never loose any data). We have several Linux systems running software raid 1 and if one of the disks fail in the mirror then the other disk can simply be mounted - is it the same procedure under FreeBSD? Eg. if one of the raids fail we will be able to mount the existing part of the raid as a regular disk? (please reply to my email address as well as to the list) Thanks in advance :) Regards -- Lasse Laursen - Systems Developer NetGroup A/S, St. Kongensgade 40H, DK-1264 København K, Denmark Phone: +45 3370 1526 - Fax: +45 3313 0066 - Web: www.netgroup.dk - We don't surf the net, we make the waves.
