Gluster 3.7.6 
'storage' is a distributed volume 

# gluster volume set storage rebal-throttle lazy 
volume set: failed: One or more connected clients cannot support the feature being set. These clients need to be upgraded or disconnected before running this command again 

I found a client connected using version 3.6.7 so I upgraded & umount/mount the gluster volume on the client but I'm still getting this error. 

I've run grep "accepted client from" /var/log/glusterfs/bricks/* | grep -v 3.7.6 and I get a few returns from the client above, all dated last week. 

I've run 'gluster volume status storage clients' and checked the connected clients manually, they're all running 3.7.6. 

/var/log/gluster/etc-glusterfs-glusterd.vol.log:

Also tried setting the diagnostics.brick-log-level logging level and got the same error.
