Hi All,
                I was wondering what effect restarting the subnet manager has on an active Spectrum Scale filesystem. Is there any scope for data loss or corruption? A 2nd similar scenario of slightly longer duration is failover to a secondary subnet manager because the primary has crashed. What effect would that have on the filesystem?
