Problem conclusion
vSnap calculates the capacity of a pool based on the capacity of the underlying disks. If a pool is backed by files created in a filesystem, vSnap did not correctly take into account the size of the files. This resulted in the pool capacity being seen as zero, and the used capacity being shown as a negative number. The problem has been resolved by updating vSnap to ensure it takes file sizes into account when calculating capacity of a file-backed pool.
