Allon Mureinik has submitted this change and it was merged. Change subject: core: Remove ImagesHandler.PerformImagesChecks ...................................................................... core: Remove ImagesHandler.PerformImagesChecks After the recent changes, PerformImagesChecks had the following functionality: For each disk: - GetImageInfo from VDSM - if it does not exist, fail - if it's status is different from the engine's status, update the engine's status. Analyzing ImageStatus' different values, this validation is useless: - OK: The engine did not issue any command regarding this image. It may have been manually removed from the storage itself, but that could also happen right after the check finishes successfully. - LOCKED: The engine is in the middle of performing a command on the image. It's status in VDSM is meaningless, as it may change any moment now. - ILLEGAL/INVALID: The engine issued a command on the image, and it was interrupted somehow (e.g., restart, network failure, etc.). The image may have been partly or fully compromised, and it cannot be trusted anyway. In conclusion, this validation NEVER returns any useful information, and thus could (and should!) be removed. For good measures, an additional validation that the disks aren't ILLEGAL in the engine side was added to the commands where it was missing, just to be safe.
