RedHat Cluster Suite And Conga – Linux Clustering

RedHat Cluster Suite And Conga – Linux ClusteringThis how to describes an easy step by step installation of the RedHat Cluster Suite on three CentOS nodes and prepare them as nodes of a cluster. You will also install the Management suite which is web based and is known as Conga.You will use three nodes to form the cluster and one node as the cluster management node and as a cluster node it will not take part. All the nodes and the management node should be resolvable either by host file entries or by DNS.Cluster Nodes:cnode1:    eth0-192.168.2.151/24 – external-lan    eth1-192.168.1.200/26 – i

High-Availability Storage With GlusterFS 3.0.x On Debian Squeeze – Automatic File Replication Across Two Storage Servers

High-Availability Storage With GlusterFS 3.0.x On Debian Squeeze – Automatic File Replication Across Two Storage ServersThis tutorial shows how to set up a high-availability storage with two storage servers (Debian Squeeze) that use GlusterFS. Each storage server will be a mirror of the other storage server, and files will be replicated automatically across both storage servers. The client system (Debian Squeeze as well) will be able to access the storage as if it was a local filesystem.
GlusterFS is a clustered file-system capable of scaling to several peta-bytes. It aggregates various storag

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On CentOS 6.3

Distributed Replicated Storage Across Four Storage Nodes With GlusterFS 3.2.x On CentOS 6.3This tutorial shows how to combine four single storage servers (running CentOS 6.3) to a distributed replicated storage with GlusterFS. Nodes 1 and 2 (replication1) as well as 3 and 4 (replication2) will mirror each other, and replication1 and replication2 will be combined to one larger storage server (distribution). Basically, this is RAID10 over network.
If you lose one server from replication1 and one from replication2, the distributed volume continues to work. The client system (CentOS 6.3 as well) w
