I’ve been playing around with VCHA and had been taking snapshots and have encountered some issues using snapshots on a VCHA enabled VCSA 6.5
You need to exercise caution when using snapshots on a VCSA that is enabled for VCHA.
Important: This is only when snapshot tasks are being done to the VCSA 6.5 VM. For all other VMs in your inventory there is no issue.
This includes taking snapshots of the current Active, reverting to snapshots of the current Active and deleting snapshots of the current Active.
For any and all of those tasks, ensure that the VCHA Cluster is in “Disabled” mode.
have you tried reinstalling?
