I know what may have happened,= =20 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=20 mdadm --revert works from there. If it does, your Centos should then brin= g=20 everything back no problem. (You've currently got what I call a Frankensetup, a very old kernel, a=20 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= =20 match anything ...) Let us know how that goes ... Cheers, Wol CAUTION!!!
