upgrade standalone hd to raid1?
Posted by ChangeGuy on April 27th, 2005


I am about to build a webserver that is supposed to have a raid1 mirror
drive system (hardware controller). I was wondering if the system could be
built with just one hd for the time being and then another hd added to make
it a true raid1 in the future. Or do I have to get the two hds at the same
time before installing the operating system?

You cannot just copy over the disk to get RAID1. There need to be space
for a RAID descriptor block. Maybe you can do the following (works
with Linux software-RAID): Add second disk, create RAID1 in degraded
mode on it (only one disk), copy data over, and then add the first
disk to the array.

Consult the manufacturer of the raid controller. It is most likely
possible.
