 Fail over with two disk hardware mirror
RAID 1, RAID 5, RAID Array, RAID Driver, Seagate external drive, Windows Server 2008, Windows Server 2008 Administration
If I currently have a two disk hardware mirror or RAID 1 can I migrate the data from them to a RAID 5 array by adding 4 more drives? Do I need all 6 drives in the array or can I make one of them hot swappable in case something goes wrong? Will it fail over automatically? I am using a Windows Server 2008 and a Perc3 RAID card. I have all 146GB Seagate drives.

Answer Wiki:
Not usually. You have to rebuild the array into a RAID 5 array which will probably require that the RAID 1 array be destroyed before the disks can be used in a new RAID 5 array. You can setup a hot spare when you build a new RAID 5 array.

Backup the disks….. kill the raid (this will wipe the disks)

Then restore the data
