Can't help directly with your question other than to ask why Hardware Raid? There have been a number of posts recently on problems setting up RAID on so called RAID controllers; if you search the archives, you'll find some useful info on the shortcomings of 'cheap' Raid controllers; generally they don't provide full RAID functionality. FWIW, I've got software RAID1 on 6 servers (2 with SATA drives) and they've all worked fine since setup using mdadm. I followed guidance from the first 3 links below. Generally, IIRC, I disabled any so called hardware RAID functionality in the BIOS or jump switches. http://juerd.nl/site.plp/debianraid http://rootraiddoc.alioth.debian.org/ http://unthought.net/Software-RAID.HOWTO/Software-RAID.HOWTO.html http://xtronics.com/reference/SATA-RAID-Debian.htm You don't need fancy new H/W for this ;) Regards Clive -- www.clivemenzies.co.uk ... ...strategies for business -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
