Glusterd/Remove-brick: Reconfigure the nfs server volfile upon remove-brick start
Problem : For remove-brick start operation all client volfiles are reconfigured except nfs server volfile. Hence, even after layout is fixed by the rebalance process, the nfs clients dont see the change and go on creating directories and files in the decommissioned brick which leads to data loss after remove-brick commit. Solution : Reconfigure the nfs server volfile for remove-brick start credit: kaushal@redhat.com spalai@redhat.com Change-Id: Ib8cd8b45a9e1f888d5e00dff65cdf77c1613a2af BUG: 1070734 Signed-off-by: Susant Palai <spalai@redhat.com> Reviewed-on: http://review.gluster.org/7162 Reviewed-by: Kaushal M <kaushal@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
