Mitaka nova/cinder LVM的代码的分布 (nova-13.0.0 cinder-8.0.0)
by wk 22 Aug '16

hi：请教个cinder的问题。使用本地的lvm做cinder的物理存储。猜测lvm相关的代码在cinder-8.0.0\cinder\volume\drivers\lvm.py里面。但是没有调用lvm的lvcreate命令: def _create_volume(self, name, size, lvm_type, mirror_count, vg=None): vg_ref = self.vg if vg is not None: vg_ref = vg vg_ref.create_volume(name, size, lvm_type, mirror_count) 真正干活的lvcreate是在： [root@opentest stack]# vi ./nova/nova/virt/libvirt/storage/lvm.py from oslo_concurrency import processutils from oslo_log import log as logging from oslo_utils import units import six import nova.conf from nova import exception from nova.i18n import _ from nova.i18n import _LW from nova.virt.libvirt import utils CONF = nova.conf.CONF LOG = logging.getLogger(__name__) def create_volume(vg, lv, size, sparse=False): """Create LVM image. Creates a LVM image with given size. :param vg: existing volume group which should hold this image :param lv: name for this image (logical volume) :size: size of image in bytes :sparse: create sparse logical volume """ if sparse: preallocated_space = 64 * units.Mi check_size(vg, lv, preallocated_space) if free_space < size: LOG.warning(_LW('Volume group %(vg)s will not be able' ' to hold sparse volume %(lv)s.' ' Virtual volume size is %(size)d bytes,' ' but free space on volume group is' ' only %(free_space)db.'), {'vg': vg, 'free_space': free_space, 'size': size, 'lv': lv}) cmd = ('lvcreate', '-L', '%db' % preallocated_space, '--virtualsize', '%db' % size, '-n', lv, vg) 很奇怪啊，难道nova使用lvm时，不是cinder来干活么？这与Laying Cinder Block (Volumes) In OpenStack, Part 1: The Basics很比一致啊，看里面的图，cinder的绿线是做管理命令。https://cloudarchitectmusings.com/2013/11…

请问有谁能把创建虚拟机经过cells调度的流程说明一下，我反复阅读代码也没有发现对cells的调用，谢谢！
