[ClusterLabs] Antw: Re: [Question] About movement of pacemaker_remote.

Mon May 11 06:22:11 CEST 2015

Hi All,

I matched the OS version of the remote node with a host once again and confirmed it in Pacemaker1.1.13-rc2.

It was the same even if I made a host RHEL7.1.(bl460g8n1)
I made the remote host RHEL7.1.(snmp1)

The first crm_resource -C fails.
--------------------------------
[root at bl460g8n1 ~]# crm_resource -C -r snmp1
Cleaning up snmp1 on bl460g8n1
Waiting for 1 replies from the CRMd. OK

[root at bl460g8n1 ~]# crm_mon -1 -Af

The gnutls of a host and the remote node was the next version.

gnutls-devel-3.3.8-12.el7.x86_64
gnutls-dane-3.3.8-12.el7.x86_64
gnutls-c++-3.3.8-12.el7.x86_64
gnutls-3.3.8-12.el7.x86_64
