(An update over the same trick with VMWare Server 1.X)

VMWare Server was declared End Of Availability on Jan/2010, while VMWare is pushing to use Player, ESX(i), vCenter, vSphere and all the “formerly known as” product names. I think that VMWare Server series are a great software, but v2.0 was sentenced to death since:

The King is dead. Long live the King.

Well, let’s see a recipe for configuring a shared SCSI bus + OCFS2 with VMWare Server 2.0.

I will use a turnkey Linux appliance in this test, because it has a very simple startup menu for configuring IP address and it’s debian based (apt-get!). Continue reading

I remember that some (old?) versions of VMWare products allowed SCSI controller to be shared between some nodes, and thus all the devices attached to this SCSI controller are accesible to all nodes: simple and neat. Perhaps that was an option only with VMWare Workstation, or ESX …

Free VMWare products -at least VMWare Server 1.0.X- can do the same despite it’s a bit tricky. Along this post I will explain how to setup this kind of shared storage between a group of VM. I’m using a CentOS 5.2 VM because it’s Linux and it’s 99.9% compatible with it’s RHEL counterpart that you can find at your favourite production environment. So, for this test I used the CentOS available at bagside that I found at the VMWare Appliances MarketPlace. Continue reading
