Not my problem !!! Seen on the opensuse mailing list - a current thread... Somebody has created a v1.0 mirror, which mounts fine on openSUSE 12.2, but not Leap 42.2. The two drives making up the mirror are sdb9 and sdc9, and the array is called md9. The filesystem on md9 is the same size as sdb9 or sdc9. The guess is the array was created, and then the file system was created on one of the sd devices. The weirdo is why 12.2 mounts the partition fine, but 42.2 won't. Has collision checking been tightened up? Might there be a change in the superblock where the filesystem has overwritten it in a manner 42.2 can detect but 12.2 can't? As I say, it's not my problem, and it's clearly an incorrect configuration, but it's weird why the older distro has no problem but the newer one won't mount it.
