The file systems offline operation gets stuck for more than 2hrs after a reboot all operation
After you perform a reboot all operation, the file systems offline operation gets stuck. Hence, few file systems are not available and the respective containers also become offline. The backup/restore operation also get stuck as the primary/media containers are offline or unavailable. (4027460)
