Change subject: Fill VDSM volumes with zeros before using them for the first time ...................................................................... Fill VDSM volumes with zeros before using them for the first time VDSM does not initialize iSCSI volumes to clean state and that causes issues when trying to read the metadata from it. The agent fails to parse random blocks since there are some random data and the checksum does not match.
