When a hypervisor was rebooted, all logical volumes which were part of an FC storage domain were automatically activated. This caused some issues as logical volumes should by activated only on request of the engine, and deactivated immediately when they are not needed. These logical volumes did not pick changes done by the SPM on the storage, which could lead to data corruption when a virtual machine wrote to the logical volume with stale metadata. The fix checks all VDSM logical volumes during LVM bootstrap and deactivates them if possible. Special logical volumes are refreshed, since they are accessed early when
connecting to storage pool, before LVM bootstrap is done. Open logical volumes are skipped because they use correct metadata when opened.
