Greetings - Hoping to hear from hunner or one of the other maintainers of the puppetlabs corosync module - there is a note on the git project page that there is currently no way to configure STONITH. Is this information current? If so, has anybody come up with a simple method of managing STONITH with corosync via puppet? -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Hello List, Any suggestions to solve the following would be most appreciated. Setup: Active/Passive Two Node Cluster. Two UPSes (APC Smart-UPS 1500 C) with USB communication cables cross connected (ie UPS-webserver1 monitored by webserver2, and vice versa) to allow for stonith/fencing OS OpenSuse Leap 42.2 NUT version 2.7.1-2.41-x86_64 Fencing agent: external/nut Problem: When power fails to a single UPS, both nodes are shutdown. The node with the still powered UPS comes back up, but requires manual intervention to keep it providing services. I would like only the node...

...if the cluster software decides that it is necessary. If my UPSes were able to connect to the network themselves, this would work, but they only have USB or serial inputs for control. I am trying to kill two birds with one stone, that is UPS protection from power failure and cluster node fencing (Stonith) with the UPS ability to cut power to a node. Somebody has done this, as there exists a fencing agent using NUT in the Pacemaker/Corosync (Linux-HA cluster software), I just don't know the best way to go about it.

Hi, I think this would be the best forum, let me know if not. I am in the middle of writing fencing scripts for Citrix XenServer virtual machines (specifically for use with Redhat Clustering, but will also work from pacemaker etc) and I noticed that XCP uses the same XenAPI (from what I can tell). Just wondering if someone would be able to test the scripts on XCP and let me know if they work.

I can manually bring the surviving node's services back up if by removing the requirement that Stonith services are enabled. I cannot get NUT to restart until I restart the 2nd node.

Bonjour, J''aimerai mettre en place un cluster sous Xen ou XenServer avec 2 serveurs dell R 710. J''aimerai pouvoir monter un cluster en utilisant l''espace disque entiere des 2 serveurs cumulés ainsi que la mémoire Quelles sont vos retour d''expériences et vos configurations?

...es drbd1_fs with pgsql There is a way to avoid that if libvirt_guest_res fails, drbd1_fs will not be stopped and then all other resources depending from drbd1_fs? Another question is about fencing. I've ridden that a cluster must have fencing to be considered as such. On CentOS 6.5 there is stonith that concerns node level fencing. For this type of fencing I must have ilo, ilom, drac, and other. It's possible to have fencing without Light-out devices, blade power control device and other? There are other device that can be used for fencing? Supposing a 2 node cluster with two server...

Hi, We''re setting up fairly large Lustre 2.1.2 filesystems, each with 18 nodes and 159 resources all in one Corosync/Pacemaker cluster as suggested by our vendor. We''re getting mixed messages on how large of a Corosync/Pacemaker cluster will work well between our vendor an others. 1. Are there Lustre Corosync/Pacemaker clusters out there of this size or larger? 2.

Hi, I want to combine all the above mentioned technologies. The Linbit pages warn not to use the drbd: VBD with HVM DomUs. This page however: http://publications.jbfavre.org/virtualisation/cluster-xen-corosync-pacemaker-drbd-ocfs2.en (thank you Jean), simply puts two DRBD devices in dual primary mode and starts Xen DomUs while pointing to the DRBD devices with phy: in the DomU config files.
