Description of problem: Thinpool target supports creation of a single metadata snapshot for thin pool metadata, so the userland may do runtime analysis of 'consistent' data (i.e. thin_check, or creation of metadata diff, doing precise analysis of space usage). There could be exactly 1 such snapshot. Maybe there could be some integration with persistent data tools, so if it knows, user requested check of live pool LV, it may automatically use this snapshot. Version-Release number of selected component (if applicable): 2.02.105 How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
