基于本地存储LVM新建虚机方案
date: 2021/12/22
auth: mmwei3
一、环境信息如下：
| IP | 角色 | VGS |
|---|---|---|
| 192.168.162.123 | 控制+计算+存储 | cinder-volumes、cinder-volumes-ssd |
| 192.168.162.124 | 控制+计算+存储 | cinder-volumes、cinder-volumes-ssd |
| 192.168.162.125 | 控制+计算+存储 | cinder-volumes、cinder-volumes-ssd |
二、需求方案：
1、虚机(卷启动)+系统盘+数据盘 三者在同一计算节点。
2、虚机可以挂本计算节点的数据盘也可以挂载其他计算节点的数据盘。
3、虚机可以使用本节点上的HDD做系统盘及云盘，也可以使用本节点上的SSD做系统盘及云盘
4、虚机(本地)+数据盘 三者在同一计算节点。
5、虚机冷迁移方案
三、环境部署部分说明
参考官方文档：
https://docs.openstack.org/mitaka/config-reference/block-storage/drivers/lvm-volume-driver.html
https://docs.openstack.org/cinder/latest/admin/blockstorage-lio-iscsi-support.html
1、每个节点新建两个vg：cinder-volumes、cinder-volumes-ssd
# 001节点
[root@rg2-test-control001 ~]# vgs
VG #PV #LV #SN Attr VSize VFree
cinder-volumes 1 4 0 wz--n- <3.64t <3.30t
cinder-volumes-ssd 2 0 0 wz--n- 278.24g 278.24g
# 002节点
[root@rg2-test-control002 ~]# vgs
VG #PV #LV #SN Attr VSize VFree
cinder-volumes 1 1 0 wz--n- <3.64t <3.59t
cinder-volumes-ssd 2 0 0 wz--n- 278.24g 278.24g
# 003节点
[root@rg2-test-control003 ~]# vgs
VG #PV #LV #SN Attr VSize VFree
cinder-volumes 1 1 0 wz--n- <3.64t <3.59t
cinder-volumes-ssd 2 2 0 wz--n- 278.24g 258.24g
2、修改相关配置文件 (解决方案一)
参考官方文档：
https://docs.openstack.org/kilo/config-reference/content/section_cinder.conf.html
https://docs.openstack.org/mitaka/config-reference/compute/iscsi-offload.html
https://docs.openstack.org/cinder/latest/admin/ts-cinder-config.html
https://docs.openstack.org/cinder/latest/admin/blockstorage-multi-backend.html
① 修改cinder-volume、cinder-api、cinder-scheduler配置
# 三个节点均需修改(或者说cinder-volume节点所在节点都修改)
# 为了保持统一cinder-api、cinder-scheduler、cinder-volume三者均修改
# iSCSI target user-land tool to use. tgtadm is default, use
# lioadm for LIO iSCSI support, scstadmin for SCST target
# support, iseradm for the ISER protocol, ietadm for iSCSI
# Enterprise Target, iscsictl for Chelsio iSCSI Target or fake
# for testing. (string value)
#iscsi_helper=tgtadm
# Method used to wipe old volumes (string value)
#volume_clear=zero
# Size in MiB to wipe at start of old volumes. 0 => all
# (integer value)
#volume_clear_size=0
[root@rg2-test-control003 ~]# cat /etc/kolla/cinder-volume/cinder.conf|egrep -w 'enabled_backends|default_volume_type'
enabled_backends = lvm,lvm-ssd
default_volume_type = lvm
[root@rg2-test-control003 ~]# cat /etc/kolla/cinder-volume/cinder.conf | grep 'storage_availability_zone'
storage_availability_zone = rg2-test-control003.ostack.hfb3.iflytek.net (cinder-volume节点的主机名, 即myhostname)
[root@rg2-test-control003 ~]# cat /etc/kolla/cinder-volume/cinder.conf | egrep -w '\\[lvm\\]' -A 30
[lvm]
volume_backend_name = lvm
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes1
iscsi_protocol = iscsi
#iscsi_helper = lioadm #这里不适用lioadm，使用默认的配置 #iscsi_helper=tgtadm,可以不写
volume_clear = zero
[lvm-ssd]
volume_backend_name = lvm-ssd
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes-ssd
iscsi_protocol = iscsi
#iscsi_helper = lioadm
volume_clear = zero
[root@rg2-test-control003 ~]#
② 修改glance-api配置
参考官方文档：https://docs.openstack.org/glance/pike/install/install-rdo.html
# 三个节点均需修改(或者说glance-api节点所在节点都修改)
[root@rg2-test-control003 ~]# cat /etc/kolla/glance-api/glance-api.conf| grep '\\[glance_store\\]' -A 10
[glance_store]
#default_store = rbd
#filesystem_store_datadir = /var/lib/glance/images/
#stores = rbd
#rbd_store_user = glance
#rbd_store_pool = images
#rbd_store_ceph_conf = /etc/ceph/ceph.conf
#rbd_volume_pool = sata_pool
default_store = file
filesystem_store_datadir = /var/lib/glance/images/
stores = file
② 修改nova-compute配置
[root@rg2-test-control003 ~]# cat /etc/kolla/nova-compute/nova.conf | grep '\\[libvirt\\]' -A 10
[libvirt]
connection_uri = qemu+tcp://192.168.162.125/system
#images_rbd_pool = vms
#images_type = rbd
#images_rbd_ceph_conf = /etc/ceph/ceph.conf
#rbd_user = nova
#rbd_secret_uuid = df5fbfad-02c7-43b2-9938-900c80d6bc99
images_type = lvm
images_volume_group=cinder-volumes1
3、修改相关配置文件 (解决方案二)
参考官方文档：
https://docs.openstack.org/cinder/pike/scheduler-filters.html
https://github.com/openstack/cinder/blob/master/cinder/scheduler/filters/instance_locality_filter.py
https://opendev.org/openstack/cinder/src/commit/40a6fff6d408f2ef0317c08fb165cc75a92c380a/setup.cfg
https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/14/html/
openstack_data_processing/instancelocality
https://specs.openstack.org/openstack/sahara-specs/specs/kilo/volume-instance-locality.html
# 在方案一的基础上新增如下配置
# 该配置可以尝试使我们的虚机实例和系统盘在同一个节点上创建
[root@rg2-test-control003 ~]# cat /etc/kolla/cinder-scheduler/cinder.conf | grep scheduler_default_filters -A 3
scheduler_default_filters=AvailabilityZoneFilter,CapacityFilter,CapabilitiesFilter,InstanceLocalityFilter
volume_local_to_instance = True # value for true or false
四、运行相关容器
# iscsi-initiator-utils scsi-target-utils.x86_64
# cinder-volume容器挂载一下-v iscsi_info:/etc/iscsi nova-compute也挂在一下
cat /etc/kolla/iscsid/config.json
"command": "iscsid -d 8 -f --pid=/run/iscsid.pid",
"config_files": []
cat /etc/kolla/tgtd/config.json

五、验证方案
1、虚机(卷启动)+系统盘+数据盘 三者在同一计算节点。
① 上传镜像
[root@rg2-test-control001 ~]# glance image-create
--disk-format raw \\
--container-format bare \\
--file /root/mmwei3/Centos-7.4.raw \\
--property hw_qemu_guest_agent=yes \\
--name Centos-7.4-lvm \\
--visibility public \\
--progress
② 新建主机聚合
# 先查看服务状态 是否正常，zone是否生效
[root@rg2-test-control001 ~]# openstack volume service list -c Binary -c Host -c Zone
+-----------------+----------------------------------------------------+---------------------------------------------+
| Binary | Host | Zone |

| cinder-volume | rg2-test-control003.ostack.hfb3.iflytek.net@lvm-ssd| rg2-test-control003.ostack.hfb3.iflytek.net |
+-----------------+----------------------------------------------------+---------------------------------------------+
[root@rg2-test-control001 ~]# nova aggregate-create

+----+--------+---------------------------------------------+--------------------------------------+
③ 新建卷类型
[root@rg2-test-control001 ~]# openstack volume type create --public --property volume_backend_name='lvm-ssd' lvm-ssd
[root@rg2-test-control001 ~]# openstack volume type create --public --property volume_backend_name='lvm' lvm
[root@rg2-test-control001 ~]# openstack volume type list
+--------------------------------------+---------+-----------+

+--------------------+--------------------------------------+
④ 新建卷及云盘
# 1、从镜像创建卷(作为系统盘)，指定availability-zone
[root@rg2-test-control001 ~]# openstack volume create \\
--image 2e3c5301-e2ed-4357-884e-f28ad0428690 --size 100 \\

#######------------------------------如果采用方案二 加入 InstanceLocalityFilter 过滤器--------------
# 此方案适用于新建虚机不建数据盘或者数据盘在其他节点或者其他存储池
# 且volume_local_to_instance = True 则新建虚机时不需要指定zone,新建系统盘时 也不需要指定zone
# 但是新建数据盘需要指定zone
# 如果新建虚机不加数据盘则直接新建便可
