There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs

Hmm. That's right. I does not exist.

Is the partition type set to FD?drew einhorn wrote:
Hi,
I'm in the process of trying mdadm for the first time
I've been trying stuff out of tutorials, etc.
At this point I know how to create stripes, and mirrors.
My stripe is automatically restarting on reboot,
but the degraded mirror isn't.
That's the problem, but now I'm having trouble fixing it.
