Overview

Notes of tricks I’ve used for the VMServer environment.

Using NFS for VM Guest

Using an IOMEGA StorCenter IX2, can’t move a VM guest from local data store to NFS CIFS data store.

Symptoms

When attempting to run the VM Guest, server complains that the disk does not support large files.

"Power On Virtual Machine" failed to complete

If these problems persist, please contact your system administrator.

Details: VMware Server cannot open one of the virtual disks needed by this VM because it is larger than the maximum file size supported by the host file system. Some remote file systems do not support files larger than 2 GB, even though the file system on the server might.Cannot open the disk ‘\\172.16.4.199\vmware\CiscoACS51\Virtual Machine.vmdk’ or one of the snapshot disks it depends on.Reason: The file is too large.

Fix

Add the following to the VM Guest config:

diskLib.sparseMaxFileSizeCheck = false

Notes & Other Gotchas

I also can’t build a new VMGuest on the NFS CIFS, so I have to build them on the local data store and then move them to NFS CIFS data store.

Due to CIFS & Permission on the IOMEGA StorCenter iX2, the folder that holds the guest VMs must have security disabled.  Something about root permissions on the StorCenter.  I don’t like it, but it works.
