Topic: Adding a third Hard drive to a raid1 configuration

[Laurent DINCLAUX]

I am running a fresh install of sme5.6. I have installed it on two 80GB hard drives. I use linux RAID1 support. The two hard drive are primary and secondary masters.

I've tried to add a third hard drive (primary slave) and then my sme box doens't  find the mirror disk on boot.

Any idea ?

[Laurent DINCLAUX]

Well in fact the slave drive I am adding contains an old SME5.6b system. When I add it to my pc a reboot, the system boots on this disck (primary slave) but my system work well without it !

PLEASE HELP!

Easy, but not free. Buy a hardware raid controller, such as the 3-ware. You can purchase a model that will handle as many as 12 drives.

Do a search for

I found a few that may be helpful to you.

I think you should zero out the partition on that hard drive with the old instal of sme on it and then try again. Connect it as a single disk drive system and do the following (see http://www.e-smith.org/faq.php3#7q23)
To remove any partition tables, perform the following commands as root:

   dd if=/dev/zero of=/dev/hda bs=512 count=1

Then reconnect the drives as a RAID system with the extra drive and see how you go with the following useful tips re partitioning etc.
