From 7aefe6fa80cfb59d891831b8a1cb0f0055ea2801 Mon Sep 17 00:00:00 2001 From: Gaurav Yadav Date: Fri, 27 Oct 2017 16:04:46 +0530 Subject: [PATCH 631/631] glusterd: persist brickinfo's port change into glusterd's store Problem: Consider a case where node reboot is performed and prior to reboot brick was listening to 49153. Post reboot glusterd assigned 49152 to brick and started the brick process but the new port was never persisted. Now when glusterd restarts glusterd always read the port from its persisted store i.e 49153 however pmap signin happens with the correct port i.e 49152. Fix: Make sure when glusterd_brick_start is called, glusterd_store_volinfo is eventually invoked. >upstream mainline patch : https://review.gluster.org/#/c/18579/ Change-Id: Ic0efbd48c51d39729ed951a42922d0e59f7115a1 BUG: 1505433 Signed-off-by: Gaurav Yadav Reviewed-on: https://code.engineering.redhat.com/gerrit/121878 Reviewed-by: Atin Mukherjee Tested-by: Atin Mukherjee Tested-by: RHGS Build Bot --- xlators/mgmt/glusterd/src/glusterd-handshake.c | 18 +++++++++--------- xlators/mgmt/glusterd/src/glusterd-op-sm.c | 9 ++++++++- xlators/mgmt/glusterd/src/glusterd-server-quorum.c | 16 ++++++++++++++++ xlators/mgmt/glusterd/src/glusterd-snapshot-utils.c | 10 ++++++++++ xlators/mgmt/glusterd/src/glusterd-utils.c | 19 +++++++++++++++++++ 5 files changed, 62 insertions(+), 10 deletions(-) diff --git a/xlators/mgmt/glusterd/src/glusterd-handshake.c b/xlators/mgmt/glusterd/src/glusterd-handshake.c index 0cd1a29f4..a09437e82 100644 --- a/xlators/mgmt/glusterd/src/glusterd-handshake.c +++ b/xlators/mgmt/glusterd/src/glusterd-handshake.c @@ -626,6 +626,15 @@ glusterd_create_missed_snap (glusterd_missed_snap_info *missed_snapinfo, } brickinfo->snap_status = 0;
