I can't help, but am really interested to know your solution when you get it.
I have avoided the raid10 personality since I could never confirm the actual layout to know that it really was mirroring. When I last tried it, all the outputs it logged including when failing and adding devices implied it was only striping--I was never convinced it worked--which was unacceptable for a ha environment. Perhaps they could improve the usability of mdadm. Instead, I have always done my own raid10 via layering raid0 on top of raid1 mirrors. This way I can make the physical topology anything I want, such as mirroring or striping across different busses. It makes it possible to boot from as well. /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
