Title
Error Message: Host does not contain enough free space -
Description
When running backup, I am receiving the error "An internal error occurred during execution, please contact Vizioncore support if the error persists. Error Message: Host xxx does not contain enough free space: (6GB Needed, 4GB Free)"
The error is the same regardless of the ESX/ESXi host hosting the VM.
-
Cause
By default vRanger is set to check free space on source ESX hosts to allow for snapshot growth during the backup process. By default this is set to 6GB.
If You have shared storage you may see this for several VMs on different hosts.
-
Resolution
Check datastore reporting low free space and free up space as needed.
This value can also be configured from tools >> options >> my jobs >> configuration.
Please be adviced, it is not recommended to reduce this setting in vRanger since it is a security measure, it is recommended to identify why the space is low (for example open snapshots exists in VMs) and reclaim that space.
