Hi Matt
This is ESX350-200808401-BG. The issue has to do with how locks are handled during snapshot commits, and other functionality that uses delta files. The fix has nothing to do with VMware tools. For ESX 3.5 updates 1 and 2, you need to install ESX350-200808401-BG (or a bundle that includes it). For ESX 3.5 Update 3, the patch is already there and you just need to activate it.
To activate it, add the following line to /etc/vmware/config prefvmx.consolidateDeleteNFSLocks = "TRUE" and reboot.
Details are in TR3428 http://www.netapp.com/us/library/technical-reports/tr-3428.html
Enjoy!
Peter

Darren,
Do you have any details on the bug that affects removing snapshots from VM's on NFS ?
And do you have any details about which version of VM tools seems to solve the problem, I thought we were upto date with versions and patches, but still seem to seeing similar problems with smvi and NFS datastores.
Thanks
Matt

Yes, the issues we're seeing are that some machines lock up when undergoing SMVI backups (and not the normal bug that affects removing snapshots from VMs on NFS storage).
The latest theory is that the fixes in the latest version of VMWare tools sorts it out. VMware don't have a firm idea of what's causing it in our environment, but we've seen numerous bugs based on the locking mechanism (which is different in NFS to iSCSI or FC).
Darren.

Having said all that, I think SMVI generally works better with non-NFS
stores; we're still having occasional issues due to NFS related
issues.
Darren --
Can you elaborate on those issues for those of us eyeing both NFS for datastores and SMVI for snap management/operations?
Thanks.
