enableStorageMaintenance
…works great for putting down the storage into maintenance mode (looking forward seeing this for secondary storage as well!).
Now the question is, after I've run it… how do I know when it is done so I can operate on the volume?
Poll using updateStoragePool and query the state for "Maintenance"? What about introducing the ability to pass in callback URLs to the REST call?
Thx.

My question remains, then: can the API introduce callbacks so we don't have to polling, especially on long running operations?
Someone would need to design / implement that, and proposals + patches
are welcome!

enableStorageMaintenance will return a job id, which can be used in queryAsyncJobResult. Here is the doc:

Yep. The purpose of quiescing is exactly as described in that document: taking a backup without powering off the VM.

Along the same lines... is there a REST command coming in 4.2 to quiesce one
or multiple virtual machines?
Quiesce means quiesce guest VM file system? Like http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1015180
4.2 will support VM snapshot for vmware, but don't know it sets quiesce flag to 1 or not.
