Expand Windows Server 2008 RAID 5 array

Hello there!

Is there any way to extend my Windows Server 2008 R2 software RAID5 volume by another drive or am I bound to recreate that volume from scratch?

Thanks for your attention.

Whether or not it is possible (I'm not sure), I'd get a full backup before I start. Then the question is redundant, and all you lose is time. – Randolph West Dec 17 '09 at 10:44

I've already asked this question here - short answer, no, it can't be done safely.

I don't believe this is possible with Windows software RAID but you could take the guesswork out of it with a little no-risk experimentation. Create a virtual machine with a bunch of virtual drives. Create a RAID 5 array and then see what happens if you try to add another drive.

I'm fairly sure that that software requires you to have added the disk to the array already, and it's just using a lot of fancy words to say that it's a partition resizing tool. – Mark Henderson♦ Jan 17 '10 at 22:49
