Deploying a Data Sharing Cluster

Cluster Configuration Options

A typical data sharing cluster must meet the following requirements:

• The cluster configuration is as follows:

a A shared storage is used as a cluster storage.

b The shared storage is mounted simultaneously to /vz on all cluster nodes.

c A clustered file system (GFS v2 or NFS) is used.

Note: In the current version of Parallels Server Bare Metal, using shared storages formatted with GFS

v2 is supported for virtual machines only.

• One and the same version of the Parallels Server Bare Metal software is installed on all servers

in the cluster.

• Only one /vz partition is created.

• The following cluster resources are used in the cluster: the /etc/init.d/vz-cluster

script and the IP address resource (not mandatory).

Configuring Shared Storages for Data Sharing

Clusters

Once you have set up Parallels Server Bare Metal on each cluster node, you need to configure a

data storage (iSCSI, Fibre Channel, or NFS) for the cluster. This data storage will then be used for

hosting the /vz partition with all virtual machine and Container data from all Parallels servers in the

cluster and will be shared by all cluster nodes. The shared data storage can reside on an NFS or

GFS v2 partition.

Note: In the current version of Parallels Server Bare Metal, using shared storages formatted with GFS v2

is supported for storing virtual machines only.
