Has anyone constructed a RAID 5 of RAID 5's using mdadm on a linux
system?

Was it reliable?

How large was it?

Thanks!

 

Seems to be a large waste of space....

Consider:

You have a bunch of "bricks" that can shuffle data between a NAS head
and a bunch of disks.

The disks are RAID'd (through the "bricks"), but if one of the bricks
themselves dies, you're kinda stuck.

But if you RAID 5 the RAID 5's, then you don't end up with massive
parity pounding, and your bricks aren't a single point of failure, and
you don't lose as much space as if you mirrored.

Sound copacetic?

Thanks for your feedback!
