I have an NFS server running on Win2k8R2 and an ESXi 4.1 host that uses NFS as a datastore for ghettoVCB backups. No server authentication; unmapped user access by uid/gid; vmkernel port with it's own ip. I can add the datastore and manipulate the file system from the ESXi SSH console.
When I run a backup job, part way through the NFS share becomes unavailable, my RDP connection to windows stops working, and I'm forced to powercycle my windows server. It's a real pain because I have to drive across town to do it. I can't tell what is dying exactly because there's nothing in the event log but I know that attempting to reconnect with RDP prompts for a username and password but goes no further. I know that the server remains pingable. I know that logging on locally prompts for a password but goes no further. Hardware problem perhaps? I changed the windows server hardware to no avail.
And now I post in desperation. There are many tutorials on the web describing many different ways to configure NFS on 2k8r2 for use with ESXi 4.1 but I found nothing describing my problem.
Does anyone successfully utilize an NFS share on Win2k8R2 as an ESXi 4.1 datastore? If so, I'd like to know about your configuration.
How the hell can a bad NFS connection take out a whole server? Pardon my language.
