[ClusterLabs] Antw: Re: single node fails to start the ocfs2 resource

Hi! I'd recommend this: Cleanly boot your nodes, avoiding any manual operation with cluster resources. Keep the logs. Then start your tests, keeping the logs for each. Try to fix issues by reading the logs and adjusting the cluster configuration, and not by starting commands that the cluster

Re: [ClusterLabs] Antw: Re: single node fails to start the ocfs2 resource

Hi, 1 - if I put a node(node2) offline; ocfs2 resources keep running on online node(node1) 2 - while node2 was offline, via cluster I stop/start the ocfs2 resource group successfully so many times in a row. 3 - while node2 was offline; I restart the pacemaker service on the node1 and then

Thanks a lot for the explanation. But other then the ocfs2 resource group, this cluster starts all other resources on a single node, without any issue just because the use of "no-quorum-policy=ignore" option. -- Regards, Muhammad Sharfuddin On 3/13/2018 7:32 PM, Klaus Wenninger wrote: On

[ClusterLabs] FW: ocf_heartbeat_IPaddr2 - Real MAC of interface is revealed

Dear folks, We are currently trying to set up a multimaster cluster and use a cloned ocf_heartbeat_IPaddr2 resource to share the IP address. We have, however, run into a problem that, when a cluster member is taken offline, the MAC for the IP address changes from the multicast-MAC to the
