I'm getting this error.
And when I try to power off the machine it doesn't let me because of the same message.
I try to access via console and nothing it doesn't let me enter the console same error.
So what do I do?

I do have around 4TB of space in the Datastore.
Please help!!!
You have three snapshots associated with this virtual machine, when a virtual machine writes to a snapshot file, it grow and grows, and grows.... you get it.... until the datastore is FULL, and then the VM fails. Snapshots are missed because they are left by virtual machines, after backup applications, or you have forgotten, after using manual snapshots.
Also VMs run poorly, e.g. performance is poor when on a snapshot.
We can work with you, to get this issue solved...in the meantime, have a read of snapshots in my EE Article, and hopefully when I submit this time, the questions is not deleted!
see my EE Article
HOW TO: VMware Snapshots :- Be Patient
What I need from you, is to follow my instructions EXACTLY and do not stray of the path, and meddle, or mess around, otherwise corruption can occur, if not done already.
1. Do you have any other datastores ?
2. Do you have other VMs which share the same datastore ?
we need some screenshots of the datastore, storage space, and a screenshot of te error message, remember WE CANNOT see what you are seeing, we need to ask you!
screenshots would help.
@Steve .... this issue is occurring on the VMware vSphere ESXi host, not in the VM.

Yes, many VMs sharing the datastore
SCREENSHOTS PLEASE of datastore and storage space.
I need to see the storage space, left, with a single datastore, how much is FREE.

We believe in human intelligence. Our moderation policy strictly prohibits the use of LLM content in our Q&A threads.
can you screenshot the error message, and also the settings of the VM Disk, in the VM.
So this is a vSAN datastore ?
what is the capacity of the datastore ?
it states, 40TB, but 75TB provisioned, are you using Thin Virtual Machine disks, and you've overprovisioned your datastore ?
and now this is a combination snapshot and thin provision.
Take a look at the Datastore contents and you will see the 9TB file there.

40TB in capacity.

e.g. Right Click the VM Edit settings, and select the disk, and lets check,
are these thin disks ?

I have a whole bunch of other information there that people need to access.

I'm afraid at present you are DOWN, and you will need to advise them of that.
okay, we need to deal with the snapshots here....
now, snapshot merging (deleting) can take many seconds, minutes, hours or days, depending upon the size and speed of your datastore. You will need to be very patient.
1. do not cancel the operation.
2. do not reboot the host servers.
3. do not power on the VM.
4. do not restart networking agents
5. do not restart vCenter Server.
6. basically do not do anything other than walk away, grab a coffee, tea, red bull....
and BE PATIENT
it will possibly sit at 90, 95, 99% and look like it's hung BUT it will complete....
You need to free up space on the datastore.
1. there is a folder called isos, can we move it or delete it some where, move to local PC etc
is there any other folders we can delete or move, storing isos on vSAN is expensive usage of stoarge ?

then remove the folder, again right click delete.

But I'm still can't delete it.
This is how the other VMs configuration looks like.

But you will need to guide me through that process.
Does this sound like a good alternative to free up some space?

We believe in human intelligence. Our moderation policy strictly prohibits the use of LLM content in our Q&A threads.
Lets not worry about what things state, we need free-up space....to start the snapshot process.
I really need some other users to access information in other virtual disks I have on that server.
Is it an option to disable the virtual disk that is full, so that I can restart the server?
Is it an option to grow the virtual disk in question so that it can let me start the VM and then I can delete a lot of files I know I can delete?

The snapshot MUST be dealt with.
I'm afraid all your disks on this server, have snapshots attached.
Even if you could remove a disk, to get it started it's only a matter of time, before it would fail again, because it could not write to disk because of the snapshot, and the danger is you could the LOSE ALL or the data in the VM could become corrupted.
Did you delete the VM, and free up some space ? and we can proceed.
The quicker you free up space, the quicker we can start the snapshot merge.

Wouldn't that delete some of the snapshots?
did you free up space on the datastore.
In the Snapshot manager there is also an option that says consolidate.
Wouldn't that delete some of the snapshots?
Possibly, I did post originally, do not stray off the path and follow my instructions, otherwise you will end up in a world, you do not want to be!
What if I go to the snapshot manager and delete the snapshots from all the VMs from there, would that help?
FREE UP SOME SPACE.
Did you delete the VM and free space ?
I just removed a virtual disk with a 1TB size.
How can we check if we have enough space now?

I went to the machine edit settings and click on removed the 1TB virtual disk that I was not using.
But when I go to the browse the data store it seems like the vmdk files are still there, should I remove those vmdk files by hand?
1TB-VDFREE.JPG
I would like to have at least 1 snapshot left.
Snapshot are NOT BACKUPS.
REMOVE THEM ALL. DELETE ALL.
What are you going to do with them ALL, rollback the server and lose all your data ?

We believe in human intelligence. Our moderation policy strictly prohibits the use of LLM content in our Q&A threads.
From the image attached to this message I think I have to delete the following files:
YYCDP-FS-01-2.vmdk
YYCDP-FS-01-2-000001.vmdk
YYCDP-FS-01-2-000002.vmdk
This is because the virtual drive deleted was 1TB in size and there are no other 1TB virtual drives in this server.
Am I correct in the file identification?
1TB-VDFREE.JPG
You don't use Snapshots are Backups do you because there seem to snapshots on this VM ?
this is very bad practice, I'm not surprised you are running out of storage space, and have used up 40TB.
Now I have to go into the snapshots and delete them all, as per your instructions above.
Correct?
EARN REWARDS FOR ASKING, ANSWERING, AND MORE.

Make sure you select DELETE ALL.
The process just began,
Wish me luck

How long does this normally take?
But 25% is quite fast...
and 25% does not mean it's not doing anything, as the indicator is a bit rubbish.
Have you been manually snapshotting ALL your VMs ?
So much for the very fast.
But it is still going.

While this process completes, I will open a new case to discuss snapshots. Can you take that case?
If you post another question myself or other experts will be glad to assist.
Should I also delete all the snapshots from the other VMs?
I just created a new question to discuss snapshots, please feel free to join in.

You are right we don't know when this is going to end.
We would recommend , not use them and backup first, and then apply changes.
You do have BACKUPS of your VMs ?
What do you use ?
If you are going to use them, Snapshot - Apply Patches - Patches Worked - Delete Snapshot.
This LONG delay is caused BY YOU, leaving the VM on a snapshot too long, and it's going to take this length of time, possibly to fix ALL your VMs.
and you've wasted lots of space, and huge overhead on your SAN, with all these snapshots.
and performance will be poor.
It's at 55%
I just hope the server starts when this snapshot deleting finishes.

and you should do this WITH ALL YOUR VMs.
But this will allow the server to start normally.
Question:
If I close the vSphere client, will the process running in the server?
DELETESNAP55.JPG
the process is completing in the back ground on the server, you don't need the client open.

How do I know if it is still running or if it got stuck?
Look at the files in the VM Folder.

the process is completing in the background on the server.
Very bad use of Snapshots!
Have you not noticed your servers getting slower.....
Some of the 00000X.vmdk files from the small virtual drives are gone, so I guess that was the supposed 55% of the process.
My estimation is that this is going to take at least all night.
Should I be able to see the size of any of these files going down during the process?
VMDKFILELIST.JPG
again, it's best to walk away, and not watch it!
Do you not have a Backup program for VMs ?
What do you use to Backup VMs ?

I'm going home, watching 55% not moving is torture.
I will connect remotely and I'll let you know if the process status changed.
Thanks.
I check the files and it is now processing the last virtual drive "the big one" 9 TB
Question:
Once the process ends successfully, I can just try to power on the VM, correct?

Question:

Yes, you can power on, you will find, all the snapshots should have gone, and you've got much storage space back.
and remember you other VMs, could also be at risk of failure, because of the Snapshots.
The server is back on, thanks for everything.
:-)
For the other servers, same procedure?
1. power off
2. Snapshot manager
3. Delete all
4. Be patient
I will take care of the snapshots in the other VMs.
I would probably gone crazy without your guidance by now, so thank you again for your patience.
Best Regards,
Cargex

For the other servers, same procedure?- almost
1. power off
2. Snapshot > Take Snapshot
2a. Wait 1-2 minutes
3. Snapshot Manager and Then - Delete all
4. Be patient

VMware, a software company founded in 1998, was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies. VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture. Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
