I know what may have happened, and what bothers me is your kernel version, 3.10. The first thing to try is to boot from up-to-date rescue media and see if an mdadm --revert works from there. If it does, your Centos should then bring everything back no problem. (You've currently got what I call a Frankensetup, a very old kernel, a pretty new mdadm, and a whole bunch of patches that does who knows what. You really need a matching kernel and mdadm, and your frankenkernel won't match anything ...) Let us know how that goes ... Cheers, Wol CAUTION!!! This E-mail originated from outside of WMA Water.
