Hello Michael,

You can use mdadm in conjunction with EVMS.  Most mdadm functions should
work.  To examine the MD superblocks, you should specify the child(ren),
not the md device (e.g. mdadm --examine /dev/evms/.node/hdb1).

I have not try mdadm --monitor.  I will look into this function.

Thanks,
Mike T.
