mdraid on top of mdraid

[Emmanuel Noobadmin <centos.admin@xxxxxxxxx>]

Is it possible or will there be any problems with using mdraid on top of mdraid?

specifically say
mdraid 1/5 on top of mdraid multipath.

e.g. 4 storage machines exporting iSCSI targets via two different
physical network switches

then use multipath to create md block devices
then use mdraid on these md block devices

The purpose being the raid storage array surviving a physical network
switch failure.

In case of duplicates, for some reason the first post isn't showing up
on the mailing list so I'm resending it.
