Hi I've search the achive but found no relevant information. I would like to add an software RAID 1 to my existing System. I have a system (FC1, Dell Precision 410 with 2x 650Mhz and 256 RAM) with 3 80GB Disks (IDE) and a small SCSI-Disk where / and /boot is but this disk I don't want to put onto the RAID disks. only /home /var and /usr these are imported the rest of the system is regulary backed up. Can you point me out where I can find some information about that. Does a software RAID1 is running on an SMP-Machine ? Is there a comparision chart software raid and hardware raid (performance ....) ? Thanks for any information Reinhard
