How do I create HA cluster ?

euroNAS Cluster uses automated tools that helps you configure it in few easy steps

This FAQ will show you the fastest and simplest way how to do it

When the cluster is installed on both machines and network cards are configured you should initialize drive or alternatively create raid array. This can be done under Storage Management.

Select the name – this name will help you differentiate drives in case you have more than just one drive.

Now we can go to actual cluster configuration – make sure that all NICs are configured prior creating cluster (later this IPs should not be changed) – you need at least 2 NICs – one for internal communication (replication network) and one for communication with network clients (corporate network). Click here on Create New Cluster.

Select here network cards that you wish to use and provide admin password of the other server. Here you should also set Network Test-IP – this IP is used by cluster to find out if it can reach the clients (it will ping them regullary). Ideally it should be more than one and should be systems that are running 24/7 – for example your router, printer, other servers ….

This can take several minutes …

Cluster is now create and you can create a cluster drive – this drive will be mirrored between 2 servers.

This drive will be assigned to one of the servers. If both servers are online selected server will be primary server for this drive – in case that primary server goes offline – secondary server will take over. You can also split the capacity and create more than one cluster drive and assign it to the other server – in this case you can balance the server load between both servers and achieve greater performance.

Now you can create ressources on this drive. HA Cluster supports following resources:

  • iSCSI Target
  • iSCSI Target Lun
  • NFS Share
  • NFS / CIFS Share
  • CIFS / SMB Share with WORM and AUDIT support
  • CIFS / SMB Share with AFP and Spotlight support

Click on create ressource ….

You can create as many ressources as you like – each ressource will be accessable from via the IP Address defined for the cluster drive where it is installed on. For each ressource you can define size.

Ressource is now ready for use and you can reach it under its IP Address – list of ressource shows you their current state and server that they are currently running on.
