Nova Bare-metal to Ironic migration
</p>
Assumptions / Requirements
- Migration is only supported *within* Juno release
- Migrating live instances between virt drivers in Nova is not tested! It is NOT recommended.
- Migrating from Icehouse-baremetal -> Juno-ironic is not supported
- The nova-compute and nova-scheduler will need to be restarted
- Icehouse Nova deployed with:
- Nova "bare-metal" driver
- Populated nova_bm database
- Nova Juno release admin upgrades applied
- Deploy-ironic kernel and ramdisk, uploaded in to glance ( DIB )
- Empty Ironic database exists
</p>
High Level Walk Through
- Start maintenance period (to prevent API service access for upgrade)
- Stop Nova services (Example)
- Update nova-compute configuration (nova.conf)
- Change settings (Example)
- Add an [ironic] section (Example)
- Remove the [baremetal] section (Example)
- Update flavor metadata to reference Ironic's deploy kernel & ramdisk (Example)
- Run ironic-nova-bm-migrate script to migrate nova-bm nodes and interfaces to ironic nodes and ports
- Start Ironic services (Example)
- Ensure proper start-up
- (Re)start Nova services (Example)
- End maintenance period
</p>
Detailed examples
Stop services
sudo service nova-compute stop sudo service nova-scheduler stop

Start Ironic services
sudo service ironic-api start sudo service ironic-conductor start
Start Nova services
sudo service nova-compute start sudo service nova-scheduler start
Update flavor
dkid=$(glance image-create --name "deploy-ironic-kernel" --public --disk-format aki --file deploy-ironic.kernel | awk ' / id / {print $4}')
drid=$(glance image-create --name "deploy-ironic-ramdisk" --public --disk-format ari --file deploy-ironic.initramfs | awk ' / id / {print $4}')
nova flavor-key baremetal set "baremetal:deploy_kernel_id"="$dkid"
