Hi all,
I'm facing some estrange behaviors related to snapshots on a customer installation. Basically taking a snapshot of a powered on virtual machine takes about 9 minutes to complete but taking a snapshot of the same virtual machine but powered of takes only 20 seconds. Obviously during this 9 minutes or so the service is interrupted for the users and this particular virtual machine has fresh windows 2003 installation.
The begining... this began yesterday when we took a snapshot of a virtual machine that has a RDM (virtual compatibility mode) of 1.7 TB and it took about 30 minutes to complete... 30 minutes without the file server. In the past we took several snapshots of this file server without any kind of problems or service interruption.
In my thoughts I have related the issue to the SAN (EMC Symmetrix) so I asked the customer to take the snapshot of the windows 2003 with a fresh install but running on local this of one of the ESX Servers (3.5 Update 4) with the same results.
This installation has been running smoothly for the past two month and no significant changes has been made on it.
Have any of you seen something like this in the past?
Thanks in advance.
Saludos/Regards
