Description of problem: On an existing gluster cluster with USS enabled volume and snapshot created & activated , i enabled brick-multiplex. Post this i executed "gluster snapshot status" which showed time out issue. Then when i am executing gluster volume status , gluster pe status, these were throwing time out errors. (Happening across all the 4 nodes) Also it has become slow for other commands as in "umount", "df -Th" Version-Release number of selected component (if applicable): glusterfs-3.8.4-22.el7rhgs.x86_64 How reproducible: Always Steps to Reproduce: 1. Have a setup ready with snapshots activated 2. Enable brick-multiplex 3. Run gluster snapshot status 4. Run gluster volume status Actual results: Error : Request timed out Expected results: Should display the status Additional info:
Although I was unable to reproduce this issue, I have a theory behind this and an upstream patch https://review.gluster.org/#/c/17088 has been posted.
downstream patch : https://code.engineering.redhat.com/gerrit/#/c/104115/
Updated to the latest gluster version i.e glusterfs-3.8.4-24 followed the steps to reproduce and was not able to see any time out errors. Enabled brick-multiplex stopped and started volume I was able to list snaps I was able to see results for volume status Seems fine to me. So marking this bug as verified.
