I'm using VMWare vSphere client on Windows 10 to connect to my company DC (OVH).
I wanted to create a snapshot of a VM (Debian) before updating the packages.
So I tried to create a snapshot of a running VM but I noticed that it slowers/blocks the VM (impact on the website).
I decided to cancel the task but since then there is a warning about disk consolidation needed.
Error Stack:
An error occurred while taking a snapshot: msg.snapshot.error-CANCELLED.
An error occurred while saving snapshot file "/vmfs/volumes/01a2faad-bed2417d/new VM/new VM-Snapshot10.vmsn".
An error occurred while saving the snapshot: msg.snapshot.error-CANCELLED.
The VM needs to be up without down-time.
What can I do ?
I'm a newbie :)

I am fairly new with VMWare myself, but its possible that there is still a "delta" file somewhere. Snapshot basically stores all the changes you make to the machine after the snapshot in a separate file known as a "Delta". Consolidating merges the files together. Try opening the snapshot manager and deleting the snapshot the process may have created (If one is present) – Cheesus Crust – 2017-08-25T12:58:47.143
If you're updating packages, you may well need to reboot, so zero down-time will be unattainable. Taking a snapshot is bound to have an impact on performance, and it can take a long time. To resolve the warning, see this reference.

I found in a VMWare Forum post that recommended creating a new snapshot (letting it finish) and then deleting it might fix the problem as well. Worth a try?
