Hi all,

I'm facing a problem with a customer, he running an ESXi Host with only 130Mb of free space. He tried to remove an snapshot of machine, but the process is very slow and he shutdown the host while deleting snapshot. Now, the snapshot does not appear in Snapshot Manager and in Virtual Machine Summary, shows the message "Virtual Machine disks Consolidation is Needed". I followed the article of Andrew Hancock (http://www.experts-exchange.com/Software/VMWare/A_10300-HOW-TO-VMware-Snapshots-Be-Patient.html) and I found one delta file of 1 TB in this virtual machine. How can I delete this snapshot without data loss?

I deleted one machine and get free space. Now the Snapshot deletion is running, the problem is: Other running machines loses network connection. Anyone faced this kind of issue before?

That's normal because committing (deleting) a snapshot is very CPU and Datastore intensive.

A little strange, CPU and memroy are very low. Only disk congestioned. I am trying to change disks shares (on machine settings, resources tab), but the host performs actions very slow too. I changed the machine settings about 30 minutes ago...

I would not fiddle with the settings whilst the snapshot is merging.

Your datastore is too slow, what datastore do you have?

how long, has the VM been running on that snapshot ?

Has it finished the merge yet?

The customer have only array (RAID 5) SAS disks. More than one month running on Snapshot. This is a very intensive use server. The other running machines continue to running, but networks doesn't function.
