Hi there,There are no fencing devices configured and therefor the cluster nodes are unable to perform a STONITH to "kill" the other node if there is any doubt that the node di... [by finnzi]
On CentOS6.2 I cannot see the cluster when I run luci on that node, luci shows the cluster fine on the other node. Also, when I run luci on the node where it works from I cannot see "uptime&qu... [by Rick_Smith]
I have two nodes, installed KVM in both. I configured both nodes as a HA cluster in SLES11 SP3.
There is one virtual system on shared storage and accessible to both the nodes. I can manually start the virtual machine on any of node as well as migrate to another node.
But when I try to start the virtual machine as a cluster resource nothing happens.
I'd like to setup a two node high availability cluster using corosync/pacemaker/drbd. For that, of course, I need fencing. As far as I understand, all IPMI/iLO/... solutions do the job, but only as long as the chassis has power. In the case that node B loses power, node A does not have any chance of using STONITH against node B.
I'd like to set up a 2-node HA-Cluster based on Ubuntu and KVM running about 30 VM's.
Both nodes are connected to a HP MSA(5TB) via Fibre Channel.
Multipathing's already working and the nodes are able to access the shared storage.
There are two main requirements:
Fail-over of running VM's from one node to the other. With downtime.
Live-Migration of VM's from one node to the other.
I am installing a simple Corosync/pacemaker/drbd high availability cluster using Centos 7 and would like to provide fencing/STONITH using custom hardware (power switches using USB connections). As such, I need to add these devices as STONITH resources in my cluster. Is there a simple dummy script I can start with?
