The name of the array probably got weird because your hostname doesn't match the homehost of the array. The array has the host name stored in its metadata, so if you're booting in an environment that doesn't have the same hostname (such as a live CD) then it'll use different (large) numbering to avoid a conflict with "local" arrays. It may also cause some other differences. The manpage of mdadm has good information. I think you can also set it to ignore the hostname entirely in mdadm.conf, but I've not personally ever tried that.
