You need to make the file system *after* creating the RAID array. You essentially made filesystems on the two devices and then erased them by creating the RAID array. Make sure the partition types are set to fd "Linux RAID autodetect" as well. BTW - you don't have to wait for /proc/mdstat to report the mirror as rebuilt before formatting mouting & using the filesystem - it will be reuilt in the background. -Eric -- Eric Sisler <esisler@xxxxxxxxxxxxxxxxxxxxx> Library Applications Specialist Westminster Public Library Westminster, CO USA Linux - Don't fear the Penguin.
