The missing piece?
.................................................... Commit Message Line 16: To avoid perfomance issues the patch introduces public method for filter invalidation Line 17: and calls it from the getDevicesVisibility. As far as getDevicesVisibility Line 18: is called to all added devices this allows to reload filters every time Line 19: after new devices has been mapped but before vgscan. Line 20: Consider adding to the commit message:
Before extending a volume group, engine invokes getDevicesVisibility() on all hosts to verify that all hosts are seeing all physical volumes. This change will cause all hosts to invalidate their filter, ensuring that the extended volume group will not become partial on any host when the storage is updated.
