Title: Snapshot Deletion Describe the issue: Documentation does not clearly state the space requirements, it only says "When the administrator deletes a snapshot, the data from the deleted snapshot and the snapshot created after the deleted snapshot are merged into a single COW volume.", without mentioning the fact that temporary file is essential step during this process. Suggestions for improvement: Customers are interested in more technical background about snapshot deletion process, similar to https://access.redhat.com/site/solutions/527613 Additional information:
