I was just made aware of a new KB article released by VMware regarding deleting large files on NFS server and starting with ESX(i) 4.1u2, there is a new parameter that has been introduced to allow for a longer delay for deleting files - http://kb.vmware.com/kb/1035332
This may help permanently solve the problem around the issues users have seen when deleting old VMs from ghettoVCBg2. I would be interested to see for those of you still having problems with deleting files on NFS system if this resolves the issue.
I am out of the office Friday, Oct 28th, and will return to the office on Thursday, Nov 3rd.
Thank you,
Ben Gray
