Date: 25/08/2010
Affected NV Version: All
Plugin version: VMware Plugin 1.0, 1.1
Application version: VCB 1.5 U2
Symptoms:
When trying to mount disks of a Windows 2008 guest for file-level backups, the VCB tools fail with an exit code of 1 and the log context reveals an error retrieving the disks of NBD_ERR_GENERIC. This is when using the NBD transport mode.
This is an issue documented by VMware in its release notes at http://www.wmware.com/support/vsphere4/doc/vsp_vcb_15_u2_rel_notes.html
Their procedure:
New: VCB file-level mount of Windows Server 2008 using NBD transport mode fails with an Disk library failed (NBD_ERR_GENERIC) error
When the disk.EnableUUID parameter in the virtual machine settings is set to True on a Windows Server 2008 virtual machine, the VCB file-level mount using NBD transport mode will either fail with a Disk library failed (NBD_ERR_GENERIC)error or might stop responding, and the vcbMounter command does not run.
Workaround: Set the disk.EnableUUID parameter in the virtual machine settings to False by performing the following steps:
a) Power off the Windows Server 2008 virtual machine through vSphere Client.
b) Click Settings > Options >General > Configuration Parameters.
c) Set disk.EnableUUID to False.
d) Save the settings.
e) Power on the virtual machine.
