How did you loose data with the raid? I would have suggested JFS on LVM on RAID. Then again, I don't know what you mean by stand-alone. Are they NAS or just external to a debian box but still part of that system (USB, eSATA, etc)? Work from the bottom up: determine your fault tolerance level and set up your raid array(s) appropriatly, put each md into a VG, make LVs, put JFS on the LVs. While you're at it, figure out how you want to back up 1.7 TB. Doug. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
