If an ESX/ESXi host fails, and that host had running virtual machines that were using swap files, those swap files continue to exist and take up disk space even after the ESX/ESXi host restarts. These swap files can consume many gigabytes of disk space so ensure that you delete them properly.


Restart the virtual machine that was on the host that failed.


Stop the virtual machine.

The swap file for the virtual machine is deleted.
