Storage service does not start unless partition locations are unique

After you upgrade to Enterprise Vault 8.0, the Storage service does not start if it detects that two or more partitions share exactly the same path. Data loss can occur if two partitions use the same location.

Enterprise Vault logs event 7131 in the event log, with the following description:

Two or more partitions are configured to use the same location.
The Storage service will not start until all partition
locations are unique.

The description then lists a partition that is in conflict with another partition.

If you see this error event you must resolve the conflict.
