CSCvf34107 - False positive alerts for High Unmanaged Disk usage on /Volume - 1

I'm currently running 6.3.0.3 on one of my sensors that is experiencing this issue. Usage racked up during an upgrade attempt to 6.4.0. Update failed and started producing the high Unmanaged Disk usage on /Volume. I opened a ticket and cleared down to 63% used. I ran the PMTOOL, rebooted the sensor and FMC several times. I'm still receiving the High Disk Usage alert and unable to upgrade. Tech recommended that I reimage the sensor, but I'm open to ideas before I settle for a reimage. Any thoughts. Below are the logs for the upgrade attempt:

Re: CSCvf34107 - False positive alerts for High Unmanaged Disk usage on /Volume - 1

In the /Volume directory of the module, there are two directories. 6.3.0 and the 6.4.0, but it’s still on 6.3.0.3 and both directories are over 15GB in usage. Guessing it created the 6.4.0 during the partial upgrade and did not rollback after failure. I removed the entire 6.4.0 directory, ran the pmtool and error cleared.
