I'll try setting up the disks as you suggest, then run the install. I did manage to get the raid10 module loaded during the install, but the option for RAID-10 would not show up in the installer. I'll try creating the RAID-10 array after loading the module also. I'm getting the feeling here already that this is probably something I ought not to mess with. This is going to be a production machine, so I may end up with a RAID-1 for /boot and /, then run RAID-10 for shared data. I suppose that would be a reasonable solution. I've got some time to mess with it for a while and I'll post back the results. thanks, scott -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
