mdadm is VERY touchy about the metadata= item in the /etc/mdadm/mdadm.conf file.
For example I've just done an upgrade and the upgrade script put metadata=0.9 in the file. This was not acceptable to "mdadm -A" only when I changed it to metadata=0.90 was "mdadm -A" able to assemble the array.
I expect the same issue happens with "metadata=1" and "metadata=1.0" -- Rob. (Robert de Bath <robert$ @ debath.co.uk>) <http://www.debath.co.uk/> -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
