[Gluster-devel] [Gluster-users] KVM lockups on Gluster 4.1.1

Sorry! I should have been more specific. I over-looked the option:

---
[root at localhost ~]# gluster volume set demo1 tcp-user-timeout 42
volume set: failed: option : tcp-user-timeout does not exist
Did you mean tcp-user-timeout?
[root at localhost ~]# gluster volume set demo1 *client.tcp-user-timeout* 42
volume set: success
[root at localhost ~]# gluster volume set demo1 *server.tcp-user-timeout* 42
volume set: success
----
Looks like you need to set the option specifically on client and server.

Regards,
