Fixed In Version: Doc Type: Bug Fix
Doc Text:
Previously, the udev device manager applied permission changes only on add events. As a consequence, using the VDSM service to connect to storage pools failed. This update ensures that udev changes permissions on all appropriate events, which enables VDSM to connect to storage pools properly.
