Without volume_size_info a Storage plugin falls back to the Implementation in PVE/Storage/Plugin.pm, which relies on `qemu-img info`. `qemu-img info` returns wrong results on a node in the case of shared volume groups (e.g. when sharing disks via iSCSI), if a disk was resized on another node (it lseeks to the end of the block-device, and this yields the old size). Using lvs directly fixes the issue, since the LVM metadata gets updated when invoking lvs. Signed-off-by: Stoiko Ivanov <s.ivanov@proxmox.com>
