Description Vivek Das 2017-04-18 14:02:05 UTC

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

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.

Comment 12 Vivek Das 2017-05-03 04:29:40 UTC

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.
