I have a qtp (qmail toaster plus) machine on an ibm 326 eserver that has 2 sata 250GB drives. The problem I have is that when the Os was installed I thought I had hardware raid on but to my avail the Os assumed to drives an installed accordingly. Here is what df has for the partitions. # df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sdb1 240362656 17843040 210309816 8% / /dev/sda1 101086 11843 84024 13% /boot none 2047316 0 2047316 0% /dev/shm

I need a raid in place on this machine. This is a live machine but I do have a lab machine to break.

I really need to move this in a live fashion without losing the data of course I have complete backups to start a new if need be but it would be nice to be able to make the change and have raid1 in place to have a some better redundancy. I guess what I am asking what are the basic steps and what warnings to look for? Thanks --Dave
