Why it did not find a valid superblock is beyond me knowledge but it sures not normal behaviour. You might want to run
Code:
fsck /dev/mapper/vg_mk...-lv_root.
and see if it gives you any errors.
What type of filesystem are on the vl? With ext3/4 you should be able to resize the partition while its mounted. Maybe the savest way would be to boot with a live cd and then resize the fs.
All in all you are doing the right thing we just have to solve the super block failure.

When using lvm dont access the drivers on a physical level but only on their lvm part. Like /dev/mapper/vg_mk..-lv-root. I'd say that as the resize2fs did not work out you don't have a filesystem on /dev/sdb3.
