"A command with VDSM tasks" - what about other types of tasks? what if after the vdsm tasks there is another part of logic, then another vdsm task (iirc, there was a legacy limitation of "one single async task in the end of the command", but this shouldn't be relevant any more). 3. "A command which invokes internal commands - By default, the internal command will not be presented as a step of the parent command." examples of the non default behavior? 4. "A customized command - an asynchronous job which its termination is decided by an event other than tasks. There are few types of scenarios for it" the examples are all described as internal implementation details - what are some actual relevant use cases/flows and what will the user see for them? you also mention AddVdsCommand here - will it's internal steps be visible to the user as part of the monitored task? 5. requirements: what about internal tasks originated by the system (SPM election, live migration due to load balancing, fencing taking place, refresh of users from a directory, etc.)? 6. STEP table, start_time is "not null" - shouldn't it be nullable? 7. UX - no main tasks view? 8. can i define a step based on a previous step failure rather than success (i.e., step 2 will be run only if step 1 succeeds, step 3 will only run if step 1 failed, step 4 could be either dependent on any of them, or run after step 2 and 3 finished, whatever their result was. 9. REST API modeling?
