It seems i found the root cause of the initial problem: there were a pair of raid superblocks on each hard drive(ex in both /dev/sdb and /dev/sdb1). Until 11.04 it somehow worked for me.

Now i've removed the unnecessary raid superblocks and everything works.
sudo mdadm --zero-superblock /dev/sdb
sudo mdadm --zero-superblock /dev/sdc

But i still wonder if it is a bug or a feature.
