Reconstruct and dump a "Missing disk"of a RAID 5 set

Post by Corsari » Thu Oct 03, 2013 3:04 pm

Hello

I'm wondering if it is available this feature:

There is a RAID 5 made of 4 disks.

One disk is missing and reconstructing the RAID using the Missing Disk feature, works perfectly, like a charm. Mean that the remaining drives are consistent and also the parity.

Now for some reasons, we need to use the 3 available drives and the available parity rotation, to reconstruct the missing disk. I mean dump its reconstruction to an disk image or even dump it directly to a blank physical hard drive.

Is this possible?

Thank you

C.

Actually, there's no physical object "missing disk". in fact, this virtual object just tells R-Studio to act as if there's a faulty hard drive in the RAID. Nothing even is calculated for it.
But that's an interesting idea, though.

And it'll be necessary to manually write some RAID metadata on the HDD.
