Moving mdadm raid volume to new OS install

[Sam Martin <sambomartin@gmail.com>]

Hi all,

I'm about to reinstall linux using 64bit wheezy dist rather than the 32bit on i inadvertently used.

I've got a copy of /etc but I'm concerned that in /etc/mdadm/mdadm.config there is no reference to the array.

The only lines that are uncommented are 

CREATE owner=root group=disk mode=0660 auto=yes
HOMEHOST = <system>
MAILADDR root

Presuably is automatically detecting /dev/md0 (the raid vol)?

Can anyone offer any opinion/advice on this?  i don't want to be in a position where i cannot get it back up.

The raid is a simple mirror at the moment, but I'm guessing I cannot use it without mdadm if it did go wrong?

thanks,
sam
