In some Ceph deployments, the installation disk will NOT be /dev/sda, instead falling someplace much different (i.e., /dev/sdl) To specify the drive to deploy the OS on, use the following procedure to determine the serial number of the drive and set this as the root device in ironic. 1. Find the serial number of the drive to install the OS on: $ for uuid in `ironic node-list | awk '{print $2}'`; do echo $uuid; ironic node-show $uuid | grep 'properties\|extra ' -A3; done <snip> 97e3f7b3-5629-473e-a187-2193ebe0b5c7 | extra | {u'newly_discovered': u'true', u'block_devices': {u'serials': | | | [u'45K1K0GJF', u'45K2KAMIF', u'45K1K0GHF', u'45K1K0GIF', u'45K1K0GGF', | | | u'45K2KAMJF', u'45K2KAMGF', u'45K2KAMHF', u'45K2KAMFF', u'45K1K0GKF', | | | u'45K1K0GLF', u'644a842042b4e5001dce4bb21c5dd148', | -- | properties | {u'cpu_arch': u'x86_64', u'root_device': {u'serial': | | | u'644a842042b4e5001dce4bb21c5dd148'}, u'cpus': u'16', u'capabilities': | | | u'profile:ceph-storage,boot_option:local', u'memory_mb': u'65536', | | | u'local_gb': u'3725'} | <snip> 2. Update the ironic node definition for this node: $ ironic node-update 97e3f7b3-5629-473e-a187-2193ebe0b5c7 add properties/root_device='{"serial": "0x4000cca77fc4dba1"}' For more details, see this: http://docs.openstack.org/developer/ironic/deploy/install-guide.html#specifying-the-disk-for-deployment
Assigning to Dan for review.
This bug is going to be targeted for a new Ceph Storage Configuration Guide for the director. This will be a whole new guide that aim to show how to configure the director and your Ceph nodes (both external or deployed). Aiming to be developing this guide during Jan-Feb period.
Sent the Ceph Storage guide out for technical review. Switching Ceph bugs to POST.
This bug was accidentally moved from POST to MODIFIED via an error in automation, please see mmccune with any questions
Setting this back to assigned due to https://bugzilla.redhat.com/show_bug.cgi?id=1330220
This should be ready and published now: https://access.redhat.com/documentation/en/red-hat-openstack-platform/8/director-installation-and-usage/54-defining-the-root-disk-for-nodes Dan, how does this section look to you? Any further additions/modifications required?
