Created attachment 1078550 [details] log from the upgraded node Description of problem: After the upgrade of one of the replica pair in the cluster from 2.1.6 to 3.1.1, the volume status doesn't show the bricks from the non upgraded nodes. Version-Release number of selected component (if applicable): RHGS 2.1 update 6 RHGS 3.1.1 latest How reproducible: Always Steps to Reproduce: 1. Install 2.1.6 on 4 nodes and create a trusted pool. 2. Create a disp. rep and 2 distributed volumes. 3. upgrade 2 nodes of the cluster from 2.1.6 to 3.1.1 (Refer install guide) 4. Observe that once the setup is upgraded, the volume status on the upgraded nodes doesn't show the bricks of the non upgraded nodes.this is observed for all the volumes in the cluster. Actual results: observe that once the setup is upgraded, and the cluster is in mixed state, the volume status on the upgraded nodes doesn't show the bricks of the non upgraded nodes.this is observed for all the volumes in the cluster Expected results: After the upgrade of the nodes and when the cluster is in mixed state, the volume status should show proper info reflecting all the bricks in the cluster. Additional info: logs are attached when the cluster was in mixed state.
This bug has been fixed in the upstream and the link for the upstream bug is: https://bugzilla.redhat.com/show_bug.cgi?id=1255694
the patch for this is at https://code.engineering.redhat.com/gerrit/#/c/59169/
the patch was pulled in 3.1.2 from 3.7.5 . So the above link( patch: https://code.engineering.redhat.com/gerrit/#/c/59169/ ) need not be merged as the fix is available. i'm abandoning the patch hence forth.
from comment 5 , the patch is available in 3.1.2 branch, so moving to on_qa
Verification of this bug is blocked by https://bugzilla.redhat.com/show_bug.cgi?id=1271999. this bug needs volume status check after updating to 3.1.2 but after update one of the node in two node cluster, peer status on updated node shows that not updated node is "Disconnected" so when i issue volume status on the updated node, it shows bricks hosted by updated node only and not non updated node bricks. so this bug will be verified once we get the build with fix of bz-1271999.
With rhgs version 3.1.2 ( glusterfs-3.7.5-6 ) verified this bug. Fix is working fine and not seeing the issue reported. so moving the bug to next state.
