Playback

Playback is an OpenStack provisioning DevOps tool that all of the OpenStack components can be deployed automation with high availability on Ubuntu based operating system.

Requirement

• The OpenStack bare metal hosts are in MAAS environment(recommend)
• All hosts are two NICs at least(external and internal)
• We assume that you have ceph installed, the cinder bachend default using ceph, the running instace default to using ceph as it's local storage. About ceph please visit: http://docs.ceph.com/docs/master/rbd/rbd-openstack/ or see the (Option)Ceph Guide below.
• nova user can be login to each compute node via ssh passwordless
• The playback node is the same as ceph-deploy node where can be login to each openstack node passwordless
• The playback node default using ~/.ssh/id_rsa ssh private key to logon remote server

Install Playback

TODO: nova ssh keys esxi backend

####(Option) Ceph Guide Create ceph cluster directory

mkdir ceph-cluster
cd ceph-cluster

Create cluster and add initial monitor(s) to the ceph.conf

playback-ceph-deploy new  CONTROLLER1 CONTROLLER2 COMPUTE1 COMPUTE2 BLOCK1 BLOCK2
echo "osd pool default size = 2" | tee -a ceph.conf

Install ceph client

playback-ceph-deploy install PLAYBACK-NODE CONTROLLER1 CONTROLLER2 COMPUTE1 COMPUTE2 BLOCK1 BLOCK2

Add the initial monitor(s) and gather the keys

playback-ceph-deploy mon create-initial

If you want to add additional monitors, do that

playback-ceph-deploy mon add {additional-monitor}

Add ceph osd(s)

playback-ceph-deploy osd create --zap-disk --fs-type ext4 BLOCK1:/dev/sdb
playback-ceph-deploy osd create --zap-disk --fs-type ext4 BLOCK1:/dev/sdc
playback-ceph-deploy osd create --zap-disk --fs-type ext4 BLOCK2:/dev/sdb
playback-ceph-deploy osd create --zap-disk --fs-type ext4 BLOCK2:/dev/sdc

Sync admin key

playback-ceph-deploy admin PLAYBACK-NODE CONTROLLER1 CONTROLLER2 COMPUTE1 COMPUTE2 BLOCK1 BLOCK2
ssh {ceph-client-node} sudo chmod +r /etc/ceph/ceph.client.admin.keyring

Create osd pool for cinder and running instance

ceph osd pool create volumes 512
ceph osd pool create vms 512

Setup ceph client authentication

ceph auth get-or-create client.cinder mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=volumes, allow rwx pool=vms'

Add the keyrings for client.cinder to appropriate nodes and change their ownership

ceph auth get-or-create client.cinder | ssh {CINDER-VOLUME-NODE} sudo tee /etc/ceph/ceph.client.cinder.keyring
ssh {CINDER-VOLUME-NODE} sudo chown cinder:cinder /etc/ceph/ceph.client.cinder.keyring

Nodes running nova-compute need the keyring file for the nova-compute process

ceph auth get-or-create client.cinder | ssh {COMPUTE-NODE} sudo tee /etc/ceph/ceph.client.cinder.keyring

They also need to store the secret key of the client.cinder user in libvirt. The libvirt process needs it to access the cluster while attaching a block device from Cinder. Create a temporary copy of the secret key on the nodes running nova-compute

ceph auth get-key client.cinder | ssh {COMPUTE-NODE} tee client.cinder.key

Then, on the compute nodes, add the secret key to libvirt and remove the temporary copy of the key(the uuid is the same as your --rbd-secret-uuid option, you have to save the uuid for later)

uuidgen
457eb676-33da-42ec-9a8c-9293d545c337

cat > secret.xml <<EOF
<secret ephemeral='no' private='no'>
  <uuid>457eb676-33da-42ec-9a8c-9293d545c337</uuid>
  <usage type='ceph'>
    <name>client.cinder secret</name>
  </usage>
</secret>
EOF
sudo virsh secret-define --file secret.xml
Secret 457eb676-33da-42ec-9a8c-9293d545c337 created
sudo virsh secret-set-value --secret 457eb676-33da-42ec-9a8c-9293d545c337 --base64 $(cat client.cinder.key) && rm client.cinder.key secret.xml

Now on every compute nodes edit your Ceph configuration file, add the client section

[client]
rbd cache = true
rbd cache writethrough until flush = true
rbd concurrent management ops = 20

If you want to remove osd

ssh {OSD-NODE} sudo stop ceph-mon-all && sudo stop ceph-osd-all
ceph osd out {OSD-NUM}
ceph osd crush remove osd.{OSD-NUM} 
ceph auth del osd.{OSD-NUM} 
ceph osd rm {OSD-NUM} 
ceph osd crush remove {HOST} 

If you want to remove monitor

ceph mon remove {MON-ID}
