Avamar Proxy Deployment Manager "verification" via logs?
Weird question, but it's a weird circumstance.
Somehow, one of the proxies at the customer I am working with has 7.7TB of storage resources associated with it, and another one has 1.3TB of storage associated with it. All other proxies have between 21 GB and 25 GB of storage associated with them.
Since the Avamar Proxy Deployment Manager (PDM) works in an "automated" manner, where in the logs can I verify whether a proxy was deployed correctly or not?
And would the addition of "extra storage" be something that the customer could potentially locate in any of the VMware environment logs if it was added separately later? (not a VM guru in terms of auditing)
All comments/feedback appreciated - thanks.
Cal C.

Thanks Ian - that is a good point.
Relative to that, can you just remind me what circumstances would cause Avamar to not be able to "clean up" leftover snapshots? From what I recall, there is a mechanism within the VM backup processes to "clean up" orphaned snapshots, but I also seem to recall that certain orphaned snapshots would not be removed and would need to be cleaned up through VMware directly.

The proxies probably have stale snapshots from production virtual machines mounted to them. I'm not aware of any circumstance where the proxy will assign itself additional storage beyond what's allocated at deployment.

There are a few different reasons we might see stale snapshots hanging around. For example, if the proxy loses communication with vCenter during the backup we won't be able to unmount the snapshot from the VM and it will stick around until it can be unmounted and deleted.
There is a tool called Proxy Mount Manager that should take care of these types of issues. The PMM package is installed on the Avamar Server and once it's configured, it pushes a utility script out to the proxies. It cleanly handles dismounting and removing stale snapshots automatically.
