120710351 seems to be the entry that is in split-brain. Is 
/staticmap/120/710/120710351 the complete path to that entry? (check if 
gfid:751233b0-7789-4550-bd95-4dd9c8f57c19 corresponds to the gfid of 710).

You can then try "gluster volume heal workdata split-brain source-brick 
gluster1:/gluster/md4/workdata /staticmap/120/710/120710351"
