Thanks to all for their help and suggetions especially Michael Maciolek, 
thomas Payerle and Darren Dunham.

Solution: As Thomas pointed out the error message explains what to do. I 
also found the link after googling

which explains the problem and solution. I had to delete all the metadb 
which were in unknown state. Once i deleted the same i was able to boot 
normally. Howerver i still need to find out how do i recover data from 
the failed metadevice as none of the disks shows failed now.
Thanks to all
