I shutdown one of our VM and clicked remove all snapshots. This was over 4 hours ago and I need the VM back online. If I start the VM does it do some damage? Or is it safe? Even if it is slower that would be better than entirely offline.

You can stop the snapshot delteion. The Data from the snapshot is stored in a seperate file, so eaven if your snapshot would be corrupt (wich wont happen) you vm woulld still work.
In vShere by recent tasks mark the snapshot delte process und right klick an select cancel task.

Should the snapshot files remove from the storage. I still see all snapshot files when I click browse storage. One 20gb file, one 13gb file and one 118mb file. And of course log files, vmx and original 550gb vmdk file.

If you have started the Snapshot Removal process it cannot be stopped, and I would not recommend forcing it to stop, otherwise you risk corruption of your VM.

Please be patient, it will finish. Be warned snapshots are not recommended to be running in production for longer than 2 days. They are not designed as backups, but to assist you in making small changes to the VM, like patching for rollback.

Do you have enough space on the datastore for the snapshot to complete the process?

What datastore do you have, SATA or SAS (SCSI)? RAID ?

Please also not this is the most common question asked on EE. Snapshots!

We have 8x 146gb 15k SAS as our storage. I just have to wait, I am beginning to see that. Backup software has somehow lefted few snapshots behind. I will update it after this is completed, so it wouldn't happen again.

If you are using third party backup software, it's always worth checking if snapshost exist.

You could use free software from Veeam called Veeam Monitor which will notify you of this condition if it exists - e.g. snapshots.

Also Nagios will also warn you

I allready have Veeam, but I haven't had time to add all the hosts to it. And this VM was running on host that hasn't been added to Veeam monitor. Believe me, it is being added as we speak.
