Very much so, that would be perfect.

I can get close to this just with the following

     gluster volume heal datastore1 info | grep 'Brick\|Number'


And if one is feeling fancy or just wants to keep an eye on progress

     watch "gluster volume heal datastore1 info | grep 'Brick\|Number'"

though of course this runs afoul of the heal info delay.

Excellent, I look fwd to that. Even if removing the locks results in the 
occasional inaccurate cout, I don't think that would mattter - From my 
POV its an indicator, not a absolute.
