We found out that this snapshot was about 400 GB in size. The VM came back online but with the known “Disk Consolidation Needed status”. Together with VMware support we were able to stop the snapshot deletion.
But the VM not only went offline for some time, but unexpectedly for hours. That could happen, depending on snapshot size and storage system.
The VM went offline because of disk consolidation. So we scheduled a maintenance window to delete the snapshot. Faster said than done. We weren’t able to add disk space because of that snapshot. We found out that there is a snapshot when the VM or service owner requested some additional disk space. So this snapshot was growing and growing. But someone created that snapshot before a software upgrade and forget to delete it. That by itself isn’t an issue, a snapshot is nothing special. We had one virtual machine with a snapshot. Recently we had a weird issue in our office.
