VMWare error, there is no more space for virtual disk

I have a VMWare host with 3 VM servers, this morning I got this message.
There is no more space for virtual disk vmdk. You might be able to continue this session by freeing disk space on the relevant volume, and clicking Retry. Click Cancel to terminate this session.
Two of the servers are yellow, and whenever I click on any tab I get the above message, what should I do?
Thanks.

It looks like you have a SNAPSHOT BINGO!

You have won a prize!

Please see my EE Article, and check to see if you have a snapshot

Please do not do anything, and confirm you have a snapshot, and I can work with you, to fix this issue.

Why do I have so many vmdk for the same machine?
INT.vmdk
INT_1.vmdk
INT_2.vmdk
INT_1-000001.vmdk
INT_2-000001.vmdk
INT-000001.vmdk
Can I delete some of them?

You have a snapshot!

You cannot just delete them, there is a procedure you MUST follow

the files 00001 are snapshot delta files.
Claude ConstantinescuAuthor Commented:
Yes, they are running on 000001.vmdk
So, I just follow Part 2 of your article, Deleting virtual machine snapshots without wasting disk space?
Andrew Hancock (VMware vExpert / EE Fellow)VMware and Virtualization ConsultantCommented:
Okay, so do you have any free space on this datastore ?

okay with the VMs OFF.

1. Take a new snapshot.
2. Wait 60 seconds.
3. Then in Snapshot Manager, select DELETE ALL
4. Wait and Be patient.

Do I do that at the host level or for each of the VM servers?
Mr TorturSystem EngineerCommented:
HI,
do what he says you are in good hands  :-)
Andrew Hancock (VMware vExpert / EE Fellow)VMware and Virtualization ConsultantCommented:
Just for the VM, in the Inventory, which has the snapshot issue.

So for VM - INT

Right Click the VM - INT in the Inventory.

Snapshot - Take Snapshot

in the Inventory.

So, after I take snapshot, I go to Snapshot Manager and say Delete all? It shows the one I just created also!!! Will that be also deleted? How long I wait before I can turn the servers on again?

Mr TorturSystem EngineerCommented:
wait for delete all operation to complete.
Yes your own manual snapshot will be deleted too as it is a delete all (snapshots) operation.
Andrew Hancock (VMware vExpert / EE Fellow)VMware and Virtualization ConsultantCommented:
Yes, DELETE ALL will remove ALL snapshots.

Be Patient, it can take seconds, minutes, hours, days, weeks.....

just Be Patient, and if it sticks at 90%, 95%, 99% and looks like it's going to hang, Be Patient, and do not mess or meddle!

time to merge, can be based on size and speed of datastore...

it will state 100% Completed when you can turn on again!

Thank you guys, I will let you know

It's done and it worked, thanks.
Since I want to put this servers in production right away, can I do the same for the other servers this weekend? Will that release more space?
Andrew Hancock (VMware vExpert / EE Fellow)VMware and Virtualization ConsultantCommented:
Yes, the servers should not be left running on snapshots!
