dd1231db-5570-4495-9984-10beb6c6fc84::ERROR::2011-01-20 17:17:07,109::storage_mailbox::143::irs::processRequest: Exception caught while trying to extend volume

number of exception in the log reach to ~3000 times. 
we should add some logic for that and block those requests till vg is extended or space is freed from it.
