glfsheal: prevent background self-heals
Problem: For a file in gfid split-brain, the parent directory ('/' during testing) was detected as possibly undergoing heal instead of split-brain in `heal-info` output. Also, it was not being displayed in `info split-brain` output for the same reason. The problem was that when `glfsheal` was run, lookup on '/' triggered a background self-heal due to which processing of '/' during `heal info` failed to acquire locks with errno=EAGAIN. Fix: Set background-self-heal-count to zero while launching glfsheal. > Reviewed-on: https://review.gluster.org/13772 > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > Smoke: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Jeff Darcy <jeff@pl.atyp.us> (cherry picked from commit b4db625d0ccb4fdc6537ed9f6e8ebeaffd1c4873) Change-Id: I153a7c75af71f213a4eefacf504a0f9806c528a5 BUG: 1467268 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reviewed-on: https://review.gluster.org/17675 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org>
