Hi Atin,
did you have time to see the logs?
Comparing debug enabled messages with previous ones, I see these added
lines on nodes where commit failed after running the commands

gluster volume reset-brick export
gl01.localdomain.local:/gluster/brick3/export start
gluster volume reset-brick export
gl01.localdomain.local:/gluster/brick3/export
ovirt01.localdomain.local:/gluster/brick3/export commit force

Does it share up more light?

Thanks,
