REVIEW: https://review.gluster.org/20015 (cli: Fix for gluster volume info --xml) posted (#1) for review on master by Sanju Rakonde
Description of problem: ======================= Geo-replication status was CREATED/ACTIVE as opposed to ACTIVE/PASSIVE. Geo-replication session was started and the following was shown as the status of the session: ---------------------------------------------------------------------------------------------- [root@dhcp41-226 scripts]# gluster volume geo-replication master 10.70.41.160::slave status MASTER NODE MASTER VOL MASTER BRICK SLAVE USER SLAVE SLAVE NODE STATUS CRAWL STATUS LAST_SYNCED ----------------------------------------------------------------------------------------------------------------------------------------------------- 10.70.41.226 master /rhs/brick3/b7 root 10.70.41.160::slave N/A Created N/A N/A 10.70.41.226 master /rhs/brick1/b1 root 10.70.41.160::slave N/A Created N/A N/A 10.70.41.230 master /rhs/brick2/b5 root 10.70.41.160::slave N/A Created N/A N/A 10.70.41.229 master /rhs/brick2/b4 root 10.70.41.160::slave N/A Created N/A N/A 10.70.41.219 master /rhs/brick2/b6 root 10.70.41.160::slave N/A Created N/A N/A 10.70.41.227 master /rhs/brick3/b8 root 10.70.41.160::slave N/A Created N/A N/A 10.70.41.227 master /rhs/brick1/b2 root 10.70.41.160::slave N/A Created N/A N/A 10.70.41.228 master /rhs/brick3/b9 root 10.70.41.160::slave 10.70.41.160 Active Changelog Crawl 2018-04-23 06:13:53 10.70.41.228 master /rhs/brick1/b3 root 10.70.41.160::slave 10.70.42.79 Active Changelog Crawl 2018-04-23 06:13:53 Version-Release number of selected component (if applicable): ============================================================ How reproducible: ================= 2/2 Steps to Reproduce: =================== 1. Create Master and a Slave cluster from 6 nodes (each) 2. Create and Start master volume (Tiered: cold-tier 1x(4+2) and hot-tier 1x3) 4. Create and Start slave volume (Tiered: cold-tier 1x(4+2) and hot-tier 1x3) 5. Enable quota on master volume 6. Enable shared storage on master volume 7. Setup geo-rep session between master and slave volume 8. Mount master volume on client 9. Create data from master client Actual results: ============== gsyncd was down on 5 nodes out of 6 Once started, the geo-rep status was ACTIVE/created Expected results: ================= gsyncd should be up on all nodes Once started, the geo-rep status should be in ACTIVE/PASSIVE
Root Cause: The root cause appeared to be in glusterd. The glusterd command [1] is returned hostUUID as same for all the bricks. Geo-rep is just gettting affected by this. I believe this existing from previous versions as well. Anyone one from glusterd should confirm why is this behaviour with tiered volume. If we observer below the nodes UUID is a9c6f6fd-3935-4ddd-ab93-506e2813c740, but xml output is showing 20981fb-cba6-46b5-ab24-32af8a62728f This was from the same IP: 10.70.41.226 [root@dhcp41-226 tmp]# cat /var/lib/glusterd/glusterd.info UUID=a9c6f6fd-3935-4ddd-ab93-506e2813c740 From gluster volume info --xml: ---------------------------------------------- <colddisperseCount>6</colddisperseCount> <numberOfBricks> 1 x (4 + 2) = 6</numberOfBricks> <brick uuid="020981fb-cba6-46b5-ab24-32af8a62728f">10.70.41.226:/rhs/brick1/b1<name>10.70.41.226:/rhs/brick1/b1</name><hostUuid>020981fb-cba6-46b5-ab24-32af8a62728f</hostUuid><isArbiter>0</isArbiter></brick> [1] gluster volume info <tiered-volume> --xml
COMMIT: https://review.gluster.org/20015 committed in master by "Atin Mukherjee" <amukherj> with a commit message- cli: Fix for gluster volume info --xml Problem: gluster volume info --xml is showing same uuid to all the bricks of a tier volume. Solution: While iterating over hot/cold bricks of a tier volume, use correct iterator. Fixes: bz#1577627 Change-Id: Icf6a9c2a10b9da453abc262a57b7884d6638e3ed Signed-off-by: Sanju Rakonde <srakonde>
