HA Issues with VSAN Beta Refresh

With the latest release of the VSAN Beta software I decided to rebuild my VSAN nested lab.  I've always used the .ova that William Lam (Blog | Twitter) created here as it's easier than having to configure the VM's individually.  I've always kept the VM defaults of 4GB RAM and 2 x vCPU's but increase the disk sizes and added an additional NIC.

After installing and configuring ESXi and then enabling VSAN it was time to enable HA.  After trying to enable I received the following error message:

The fdm-installer.log showed the following:
fdm-installer: [47599] 2013-12-17 10:35:51: Logging to /var/run/log/fdm-installer.log
fdm-installer: [47599] 2013-12-17 10:35:51: extracting vpx-upgrade-installer/VMware-fdm-eesx-2-linux-1440532.tar.gz...

fdm-installer: [47599] 2013-12-17 10:35:53: All done! Status: 0
The no space left on the device error confused me so in order to rectify the issue I tried the following:

  1. Increases the size of the VMDK used for the ESXi installation from 2GB to 5GB
  2. Inflated the ESXi installation VMDK so it was Thick Eager Zero'd just in case this was causing any strange issues
  3. Rebuild the nested environment manually (not using the .ova supplied by William Lam)
Not of the above resolved the issue.  After raising it in the VSAN Beta forums Duncan Epping (Blog | Twitter) advised to increase the memory assigned to the nested VSAN VM's from 4GB to 6GB.  In my previous nested VSAN environment I had no issues running VSAN with 4GB.  After increasing all three hosts to 6GB the FDM vib installed and HA enabled successfully.
