From 87501a984a96223012d7878ccc689510b2c3d77b Mon Sep 17 00:00:00 2001 From: hari gowtham Date: Mon, 16 May 2016 10:55:17 +0530 Subject: [PATCH 165/167] tier/cli : printing a warning instead of skipping the node back-port of : http://review.gluster.org/#/c/14347/8 back-port of : http://review.gluster.org/#/c/14459/ Problem: skipping the status of the nodes down creates confusion to the user as one might see the status as completed for all nodes and while performing detach commit, the operation will fail as the node is down Fix: Display a warning message Note: When the last node is down (as per the peer list) then warning message can't be displayed as the total number of peers participating in the transaction is considered to be the total count. >Change-Id: Ib7afbd1b26df3378e4d537db06f41f5c105ad86e >BUG: 1324439 >Signed-off-by: hari gowtham >Change-Id: Id797bb45433c442f63b189ad16e0e95492a43721 >BUG: 1337908 >Signed-off-by: hari gowtham Change-Id: Ifed8767729eaf6835ce4aef4f519d3ea509101a4 BUG: 1322695 Signed-off-by: hari gowtham Reviewed-on: https://code.engineering.redhat.com/gerrit/74790 Reviewed-by: Atin Mukherjee Tested-by: Atin Mukherjee --- cli/src/cli-rpc-ops.c | 30 +++++++++++++++++++++++++----- tests/basic/tier/new-tier-cmds.t | 16 ++-------------- tests/tier.rc | 13 +++++++++++++ 3 files changed, 40 insertions(+), 19 deletions(-) diff --git a/cli/src/cli-rpc-ops.c b/cli/src/cli-rpc-ops.c index a3787c4..ea25b0a 100644 --- a/cli/src/cli-rpc-ops.c +++ b/cli/src/cli-rpc-ops.c @@ -1509,7 +1509,8 @@ out: } int -gf_cli_print_rebalance_status (dict_t *dict, enum gf_task_types task_type) +gf_cli_print_rebalance_status (dict_t *dict, enum gf_task_types task_type, + gf_boolean_t is_tier) { int ret = -1;
