Upgrading RAID 1 array

By coolnumber_9 ·
I'm looking to upgrade the OS drives in my fileserver, which are in raid 1 array currently. I will be upgrading to 2 new larger drives and would like to if possible copy the image of the first set so i would not have to reinstall everything. What would be the best way to go about doing this, and what programs are best for the task? OS is windows server 2003

ghost (make an image) the OS to storage, replace the drives, configure the new RAID in the RAID controller, and ghost the image back on.... Thats what I would do...

That's pretty much what i was planning, I know my way around computers pretty well, just never done too much with raid. I wasn't sure if you could ghost raid 1 or not. thanks for the info ill give it a shot.

Upgrading RAID

by christianshiflet In reply to Upgrading RAID 1 array

With most RAID controllers you should be able to:
1-break the array
2-replace one of the drives with a new, larger drive
3-rebuilt the array
4-repeat steps 1-3 with the other drive
This results in a RAID 1 array with your new, larger disks. I would also ensure a good backup before doing this. I hope this helps.

Not sure..

but one problem I see with this, is the newer disk may have a different RPM speed which could cause some issues. Have never tried it, but I do know that in any RAID configuration you want all spindles to be at the same specs.

I absolutely agree that long term, the drives should be identical in size and speed for the most efficient array. I have, however, had success growing arrays in the manner described since you are never actually changing or using the array when it has mis-matched drives, but only rebuilding it twice going from 2 identical drives to 2 new identical, larger drives.
