Hi, I''m using xen on two-node redhat cluster (CVS devel version), using lvm as storage backend. redhat cluster is used to synchronize LVM metadata (using clvmd) and as storage for domain configs and dom-U kernels (with gfs). Latest version of redhat cluster works with xen-2.0.4, but not with xen-2.0-testing. ccsd failed to start on 2.0-testing. Anyone knows what the problem is? I

Hi? All: I have two physical machines as KVM hosts (clusterA.RHCS and clusterB.RHCS) , an iscsi target set into GFS. All I want is a HA Cluster which could migrate all the virtual machines on a node to another when the first node failed into some error status.

Hello, we are running CentOS 4.3 and the latest cluster suite packages from the csgfs yum repository for this release and need to delete a cluster member. According to the documentation we need to restart all cluster related services on all remaining nodes in the cluster after the node has been removed. This is a four node cluster so removing one node obviously degrades the cluster to three

I want to set up a cluster that is used for web hosting (RHCS cluster). Recently, I experimented with a 2 node cluster and was able to run it successfully. However, I have started facing some issues with Apache, which I had configured as a service using the Cluster configuration tool. To do this Apache needs a floating IP address. This address is in addition to the network interface IP address.

Hi all, I'm happy to announce a new tutorial! https://alteeve.com/w/2-Node_Red_Hat_KVM_Cluster_Tutorial This tutorial walks a user through the entire process of building a 2-Node cluster for making KVM virtual machines highly available. It uses Red Hat Cluster services v3 and DRBD 8.3.12. It is written such that you can use entirely free or fully Red Hat supported environments.

Does anyone have OCFS2 running with the "Red Hat Cluster Suite" on RHEL? I'm trying to create a more or less completely fault tolerant solution with two storage servers syncing storage with dual-primary DRBD and offering it up via multipath to nodes for OCFS2. I was able to successfully multipath a dual-primary DRBD based GFS2 volume in this manner using RHCS and GNBD. But switched

Hello, I followed the steps at http://www.enterprisenetworkingplanet.com/netos/article.php/3487081 for adding a v3.0.21a samba and winbindd server to a MsAD domain and configuring nsswitch.conf to find passwd and group info from winbind. This seems to have worked out fine, except that I can't 'see' or 'recognize' certain groups via getent or via wbinfo -g. E.g. I can see the

I am using RHEL 4.4 with RHCS and a two node cluster. Only one node is "Active" at a time, it creates a mount to the partition, and if there is an issue RHCS will fence the device and then the other node will mount the

Hello, I'm planning migration of current two clusters based on CentOS 6.x with Cman/Rgmanager going to CentOS 7.x and Corosync/Pacemaker. As the clusters and their services are on the same subnet, and there no particular security concerns differentiating them, I'm also evaluating the option to transform the two clusters into a unique 4-node one during the upgrade. Currently I'm
