Hi there, Can anyone help ...... I have 2 new 9 gig scsi drives that I have installed onto my linux machine. I did a fdisk on both (full size) Then I did a mkfs on both. So now I can mount the two drives no problem mount /dev/sdb1 /mail2 mount /dev/sdc1 /mail3 I wanted to create a raid0 setup for those 2 disks. I followed the software raid HOWTO and made the /etc/raidtab to match. I then typed in mkraid /dev/md0 which worked I then formated the drive and mounted it. When I rebooted I got errors .... so I moved the etc/raidtab to /etc/raidtab.old and then I could get back in. After doing that I tried to do the mkraid again and it now says (and changing back the etc/raidtab) handling MD device /dev/md0 analyzing super-block disk 0: /dev/sdb1, 8891376kB, raid superblock at 8891264kB /dev/sdb1 appears to be already part of a raid array -- use -f to force the destruction of the old superblock mkraid: aborted, see the syslog and /proc/mdstat for potential clues. proc/mdstat now looks like this Personalities : [raid0] read_ahead 1024 sectors unused devices: <none> I also tried that -f flag but it just gives me a warning What must I do .... and how do I set it up so that it starts automatically ? Thanks for the help Mark
