Hi!
I need to ask how do you correctly configure nfs to be used with
openstack-ansible newton (14.0.6). I think it is great that there is an
production example file that uses nfs for glance and cinder
(openstack_user_config.yml.prod.example) but the cinder config is not
working for me.
I use this config for storage_hosts, only changing ip, and share from
production example:
storage_hosts:
XxXx:
ip: 172.22.5.9
container_vars:
cinder_backends:
limit_container_types: cinder_volume
cinder_nfs_client:
nfs_shares_config: /etc/cinder/nfs_shares
shares:
- ip: "172.22.20.254"
share: "/nfs/cinder/production"
And this is the failure when running os-cinder-install.yml
TASK [os_cinder : Add in cinder devices types]
*********************************
fatal: [XxXx_cinder_volumes_container-080139bd]: FAILED! => {"failed":
true, "msg": "the field 'args' has an invalid value, which appears to
include a variable that is undefined. The error was: 'dict object' has
no attribute 'volume_backend_name'\n\nThe error appears to have been in
'/etc/ansible/roles/os_cinder/tasks/cinder_backends.yml': line 30,
column 3, but may\nbe elsewhere in the file depending on the exact
syntax problem.\n\nThe offending line appears to be:\n\n\n- name: Add in
cinder devices types\n ^ here\n"}
OK, so volume_backend_name is missing. The playbook runs if I add
volume_backend_name to the config like this:
storage_hosts:
XxXx:
ip: 172.22.5.9
container_vars:
cinder_backends:
limit_container_types: cinder_volume
cinder_nfs_client:
volume_backend_name: cinder_nfs
nfs_shares_config: /etc/cinder/nfs_shares
shares:
- ip: "172.22.20.254"
share: "/nfs/cinder/production"
But now there is no /etc/cinder/nfs_shares file in the
cinder-volumes-container so the nfs share will not be mounted. This is
because the "Create nfs shares export file" task in
cinder_post_install.yml doesn't see that cinder_nfs_client is defined.
You also get this in cinder.conf:
enabled_backends=cinder_nfs_client
# All given backend(s)
[cinder_nfs_client]
volume_backend_name=cinder_nfs
nfs_shares_config=/etc/cinder/nfs_shares
shares=[{u'ip': u'172.22.20.254', u'share': u'/nfs/cinder/production'}]
This configuration works for me:
storage_hosts:
XxXx:
ip: 172.22.5.9
container_vars:
cinder_storage_availability_zone: cinderAZ_1
cinder_default_availability_zone: cinderAZ_1
limit_container_types: cinder_volume
cinder_backends:
cinder_nfs:
volume_backend_name: cinder_nfs
volume_driver: cinder.volume.drivers.nfs.NfsDriver
nfs_mount_options:
"_netdev,auto,rw,intr,noatime,async,vers=3,proto=tcp,wsize=1048576,rsize=1048576,timeo=1200,actimeo=120"
cinder_nfs_client:
nfs_shares_config: /etc/cinder/nfs_shares
shares:
- ip: "172.22.20.254"
share: "/nfs/cinder/production"
BUT when I look in the inventory file (openstack_inventory.json) it
doesn't look like this configuration is limited to cinder_volume
containers even if "limit_container_types: cinder_volume" is used. So
now I feel it is time to ask how a correct configuration should look like.

Andreas
