[Users] Storage domain issue iSCSI

[Shu Ming]

I think the error is clear.  Engine was expecting a master storage 
domain metadata format version 3, while the master storage metadata gave 
version 4.   I am wondering if the master storage domain metadata was 
corrupted during the power off.

See: the error came from.
Thread-54::ERROR::2012-11-29

master domain 68d8b0e2-c348-4cfe-a896-08c62d491dfb does not have 
expected version 3 it is version 4

See: 'MASTER_VERSION=4' below:
