Configure HP Scalable NAS to provide HA for Samba
When the configuration files are in place, you can create a virtual host and a
CUSTOM service monitor for each share. The following example shows this process.
NOTE:
Samba shares must be mounted when setting up the CUSTOM service monitor. If
the shares are not mounted, the service monitor will generate an error reporting that
the monitor probe failed on the specified server when it was started.
In the example, a virtual Samba server called cifs1 provides access to the PSFS
filesystem /mnt/data1. The virtual Samba server is hosted by node 99.12.10.104
as the primary and node 99.12.10.105 as the backup.
This example is configured as follows:
• A virtual host (99.12.10.205) is created with node 99.12.10.104 designated
as the primary and 99.12.10.105 designated as the backup. The virtual host
must be added to the DNS name service or to the /etc/hosts file on both
servers.
• A CUSTOM service monitor is created on the new virtual host. The service monitor
must have the same name as the virtual Samba server (cifs1 in this example). This
monitor watches the Samba service on the primary node. If the node fails or the
service goes down, the virtual host will fail over to the backup node. The service
monitor then runs the smb_meth script located in /opt/hpcfs/methods and
starts Samba operations on the backup node. Clients then reattach to the filesystem
via the virtual host on the backup node.
To begin the configuration, select node 99.12.10.104 on the Management Console,
right-click, and select Add Virtual Host. On the Add Virtual Host dialog, specify an
Application Name such as FILE_SERVING (this field is optional). Under Policy, select
the NOFAILBACK option. In the Network Interfaces section of the dialog, select node
99.12.10.104 as the primary and node 99.12.10.105 as the backup. Then click
OK to create the virtual host.
