    geo-rep: Fix invalid disk size in gverify.sh
    
    Problem:
            Due to the wrong interpretation of disk size, gverify.sh script
    exits in between with error "integer expression expected".
    This error can be observed, only if gverify.sh is run standalone.
    
    Solution:
            Fix the interpretation of disk size.
    
    Also, verify that master and slave's gluster version are same.
