VMware KB1007566 – Monitor Snapshot Deletion

VMware updated a KB today on how to monitor snapshot deletion.  This is especially useful for large snapshots that “time out” for vCenter because they take more than 5-10 minutes to complete.  I have been using this exact procedure for years and never thought to blog it…for some insane reason.

Read the KB here.

Basically, use the watch command on the *.vmdk files in the VM datastore.  You can use -n to set a refresh interval and -d to show the change in size between refreshes.  However, the most important information is what base .vmdk file is being written to and when.  This touch timestamp will give you more information on which disk is in progress, which has not yet started, and what is already done.
