            Bug ID: 1306922
           Summary: Self heal command gives error "Launching heal
                    operation to perform index self heal on volume vol0
                    has been unsuccessful"
           Product: GlusterFS
           Version: 3.7.7
         Component: replicate
          Keywords: Triaged
          Severity: high
          Assignee: bugs at gluster.org
          Reporter: ravishankar at redhat.com
                CC: bugs at gluster.org
        Depends On: 1294612, 1302291, 1200252



Description of problem:
1. create a 1x3 replica using a 3 node cluster
2. Kill one brick, run 'gluster vol heal <volname>`

RCA:
If any of the bricks is down, glustershd of that node sends a -1 op_ret to
glusterd which eventually propagates it to the CLI. If op_ret is non zero, CLI
prints "Launching heal...unsuccessful". For the bricks that are up and need
heal, the healing happens without any issues.

A reasonable fix seems to be to print a more meaningful message on the CLI like
"Launching heal operation to perform index self heal on volume vol0 has not
been been successful on all nodes. Please check if all brick processes are
running."
