-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 if this device does true hardware raid, once that is configured in your cards bios, it will only show up as a single /dev/sdb or whatever in linux. typically you have to assign the drives in the bios and then create a logical disk using the raid card bios. if this can't be done, then the card doesn't appear to be capable of hardware raid and your stuck with mdadm (software raid) - which actually is very good at keeping the overhead to a minimum. it appears others had the same issue: http://ubuntuforums.org/showthread.php?t=268570&page=2 1:might want to update to the latest cards firmware. 2:try Centos 5.0 or update kernel/driver justin.vogt at bold.k12.mn.us wrote: > I am attempting to setup a bacula raid device I have a Promise 4310 4 port > raid sata device and in the device bios I have it setup for raid 5.
