cinder-backup驱动配置

一、后端采用nfs
1、安装nfs客户端

# yum -y install nfs-utils

• 1

2、配置/etc/cinder/cinder.conf

[DEFAULT]
backup_driver = cinder.backup.drivers.nfs
 
backup_mount_point_base = $state_path/backup_mount  
backup_share=172.16.8.99:/backup
格式：<hostname | ipv4addr | ipv6addr>：<share path>

二、后端采用glusterfs
1、安装glusterfs客户端

# yum --enablerepo=epel -y install glusterfs glusterfs-fuse

• 1

2、配置/etc/cinder/cinder.conf

[DEFAULT]
backup_driver = cinder.backup.drivers.glusterfs
glusterfs_backup_mount_point = $state_path/backup_mount
glusterfs_backup_share = 172.16.8.90:/vol_striped
格式：<hostname | ipv4addr | ipv6addr>：<gluster_vol_name>

三、后端采用ceph

[DEFAULT]
backup_driver = cinder.backup.drivers.ceph
backup_ceph_conf=/etc/ceph/ceph.conf
backup_ceph_user = cinder-backup
backup_ceph_chunk_size = 134217728
backup_ceph_pool = backups
backup_ceph_stripe_unit = 0
backup_ceph_stripe_count = 0

四、后端采用swift

[DEFAULT]
backup_swift_url = http://10.146.32.17:9024/v1/
backup_swift_auth_url = http://192.168.0.5:5000/v3
swift_catalog_info = object-store:swift:publicURL
backup_swift_auth = per_user
backup_swift_auth_version = 3
backup_swift_container = volumebackups
backup_swift_object_size = 52428800
backup_swift_block_size = 32768
backup_swift_retry_attempts = 3
backup_swift_retry_backoff = 2
backup_swift_enable_progress_timer = true
backup_driver = cinder.backup.drivers.swift

五、重启cinder-volume、cinder-backup服务

# systemctl restart openstack-cinder-volume  openstack-cinder-backup

• 1

六、horizon启动cinder backup功能，配置/etc/openstack-dashboard/local_settings

OPENSTACK_CINDER_FEATURES = {
    'enable_backup': True,
}
