OpenStack-RBD 导入镜像

方法 1

• 使用命令导入假镜像

  openstack image create "Ubuntu18.04" \
  --file ~/cirros-0.4.0-x86_64-disk.img \
  --disk-format raw --container-format bare \
  --property hw_scsi_model=virtio-scsi \
  --property hw_disk_bus=scsi \
  --property hw_qemu_guest_agent=yes \
  --property os_require_quiesce=yes \
  --property os_type=linux \
  --property os_admin_user=root \
  --min-disk 20 \
  --min-ram 2048 \
  --public
  
  # ................
  # id | ef85323a-c0f1-4452-922c-bdb8592fddde
  # .................

• rbd 导入

  # 解除快照保护
  rbd snap unprotect images/ef85323a-c0f1-4452-922c-bdb8592fddde@snap
  # 删除快照
  rbd snap rm images/ef85323a-c0f1-4452-922c-bdb8592fddde@snap
  # 删除镜像
  rbd rm images/ef85323a-c0f1-4452-922c-bdb8592fddde
  # 导入镜像 ubuntu18.04.raw
  rbd import ubuntu16.04.raw images/ef85323a-c0f1-4452-922c-bdb8592fddde
  # 创建快照
  rbd snap create images/ef85323a-c0f1-4452-922c-bdb8592fddde@snap
  # 保护快照
  rbd snap protect images/ef85323a-c0f1-4452-922c-bdb8592fddde@snap

• 计算镜像md5和sha512值

  # 计算md5值
  md5sum ubuntu18.04.raw
  # ba3cd24377dde5dfdd58728894004abb    ubuntu18.04.raw
  
  # 计算 sha512值
  sha512sum ubuntu18.04.raw
  # b795f047a1b10ba0b7c95b43b2a481a59289dc4cf2e49845e60b194a911819d3ada03767bbba4143b44c93fd7f66c96c5a621e28dff51d1196dae64974ce240e   ubuntu18.04.raw

• 连接数据库，更新数据

  UPDATE `glance`.`images`
  -- 镜像大小
  SET `size` = 21474836480,
  -- 镜像md5值
  `checksum` = '7324c73bee3216b5c7a9d27370eb1774',
  -- sha512 校验
  `os_hash_algo` = 'sha512',
  `os_hash_value` = '5ee4ca048ef161f661cf308654cc7e7bdcb9af6905447c1b098aa3df09a27fd8468ee7573f3e092051422c07e6ee67fb1aab5119172c06d551005b5192562778'
  WHERE `id` = 'ef85323a-c0f1-4452-922c-bdb8592fddde';

方法 2

• 导入脚本

IMAGE_URL="rbd://$(grep fsid /etc/ceph/ceph.conf | awk -F '=' 'NR == 1 {print $2}' | sed 's/ //g')/images/$IMAGE_ID/snap"
IMAGE_OWNER=`openstack project show admin -c id -f value`
