I also added windows build so that people can help with testing also on windows. It's a static build, no need for installer, just single zipped .exe file. No dependencies.
It isn't clear why you are trying to change the master at this time. Can you explain? What is the status of the two hosts that have been patched and rebooted?
@irtaza9 it scans all the VDI's on the SR to see if something has changed, if there's a need for coalesce and so on.
I dont think it will be a big issue if you increase the auto-scan-interval value to lets say 5 minutes (300 seconds), but do remember, that everything regarding the VDI's on the SR will take up to 5 minutes to update, as well as triggering coalesce after removing snapshots.
