Subject: [Cluster-devel] [ClusterLabs] DLM connection channel switch take too long time (> 5mins)
Date: Thu, 08 Mar 2018 19:03:19 -0700	[thread overview]
Message-ID: <5AA25BE7020000F9000AE041@prv-mh.provo.novell.com> (raw)

Hello David,

If sctp implementation did not fix this problem, there is any workaround for a two-rings cluster?
Could we use TCP protocol in DLM under a two-rings cluster to by-pass connection channel switch issue?

Thanks
Gang
