Hi, I'm sure there are solutions to make things work, but personnaly, I don't feel confortable with a RAID system that acts that way, and that is supposed to make the whole system more robust and problem-free. I used to play with hardware SCSI RAID controllers, and was never able to trash the system. Arrays are being rebuilt in the background, that's just great. I hope this is the kind of ease and quality I will get with the 3WARE raid controller I have ordered... Apparently, everyone says very good things about 3WARE. --------------- Philippe Lang Attik System _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
