Well, I must do a mirror on a client, that's using RHEL 4.4, of a disk in use and I dont know how to do it. I have read something about the mdam command, but it's not too clear for me...
Do you know a good tutorial or "how to" to do the raid 1 or mirror from a disk in use?
EDIT: because, it's neccesary to do/have a fd partition? Because I cant change or alter the disk in use.... and it's doenst have a fd partition
