Raid 5 with 12 drives

Hi,
I have here a RAID 5 with 12 drives, where I've imaged them all.
But I'm running version 13.8 and only supports up to 10 drives.
Is there an update or a new version that supports 12 drives?

mmm, I do not know your situation, but it would be advisable in any Raid 5 situation to use as much of the original hardware as possible. i.e the raid controller to which the drives were connected (very important), the server backplane to connect the drives to etc.

There are so many variables working with Raid5 (original Sequence (important), block sizes etc.)

If you do not know the original sequence of the drives, it is almost impossible to reconstruct the volume, especially with more than 3 drives in the Raid.

The easiest way to analyse in a situation like yours would be to get the drives as close to their original state as possible (in the same server, with the same controller.) Even different Firmware can come into play..I have found that it is sometimes neccesary to recreate the complete volume if config was lost(original drive sequence and default controller settings)and recover from there.

It remains a tricky situation though

Hope this helps

Good luck

It will be possible to assemble a RAID 5 of up to 16 component disks in v14.5 and later. Plus one additional RAID 5 pattern will be supported at that time: Forward Dynamic Parity = Right Synchronous (used in Linux software RAIDs).
