For detailed information check the Cluster Project Page site at sourcewareorg/cluster Listed are the packages used in both GFS (Cluster Components Old) and GFS 2 (Cluster Components New) Here you will find links for documentation like the clustering FAQ The Red Hat GFS Administrators Guide can be helpful but may be dated The guide can be found on the Red Hat documentation page located at redhatcom (Bear in mind that GFS now uses logical volumes instead of pools to set up physical volumes)

The original GFS, GFS 1, used a variety of separate packages for cluster servers and management tools, which did not appear related just by their names With GFS 2, these packages have been combined into the cman and gfs2-tools packages Here you will find tools such as fence, cman cluster manager, dlm locking control, and ccs cluster configuration Cluster configuration is supported by the Cluster Configuration System, ccs Fencing is used to isolate failed resources It is supported by in the fence server LVM cluster support is located in a separate package like lvm2-cluster (Fedora) or clvm (Debian) To run a cluster, you need both a cluster manager and locking mechanism cman with the Distributed Lock Manager (dlm) implements cluster management and locking cman manages connections between cluster devices and services, using dlm to provide locking The dlm locking mechanism operates as a daemon with supporting libraries All these services are invoked by the cman script, which checks the /etc/clusterconf file for cluster configuration
Encode Bar Code In None

Creating EAN-13 Supplement 5 In None
Using Barcode generation for Software Control to generate, create EAN 13 image in Software applications.
To start the GFS file system, you run the cman script to start the needed daemon and implement your configuration The cman script will run the ccsd to start up configuration detection, fenced for fencing support, dlm_controld for cluster management dlm locking, and cman for cluster management The script will check for any GFS configuration settings in the /etc/sysconfig/ cluster file You use the gfs2 script to mount your GFS 2 file systems To shut down the GFS file system service, you use the cman script with the stop option

Distributed Network File Systems
Implementing a GFS 2 File System
To set up a GFS 2 file system, you first need to create cluster devices using the physical volumes and organize them into logical volumes You use the CLVM (Clustering Logical Volume Manager) to set up logical volumes from physical partitions (in the past you used a volume manager called pool to do this) You can then install GFS file systems on these logical volumes directly CLVM operates like LVM, using the same commands It works over a distributed network and requires that the clvmd server be running You then configure your system with the Cluster Configuration System Create a /etc/ clusterconf file and set up your configuration The configuration will include information like the nodes used, the fencing methods, and the locking method used Consult the cluster conf Man page for configuration details Test the configuration with the ccs_test tool
You then use the ccs_tool to create clusterccs, fenceccs, and nodeccs configuration files These files are organized into a CCS archive that is placed on each node and cluster device On each node, start the ccsd configuration, the fenced fencing server, and the locking method you want to use, such as dlm Check the respective Man pages for details on the locking servers You can start the servers with their service scripts, as noted previously To create new file systems on the cluster devices, you use the gfs2_mkfs command and mount them with the -t gfs2 option The following command creates a GFS file system on the /dev/gv0/mgfs and then mounts it to the /mygfs directory For gfs2_mkfs, the -t option indicates the lock table used and the -p option specifies the lock protocol The -j option specifies the number of journals
