Doc Type:	Enhancement
Doc Text:	This enhancement enables the distribution of per-node hieradata, matching the nodes from their UUID (as reported by 'dmidecode'). This allows you to scale CephStorage across nodes equipped with a different number/type of disks. As a result, CephStorage nodes can now be configured with non-homogeneous disk topologies. This is done by provisioning a different configuration hash for the ceph::profile::params::osds parameter.

Description Giulio Fidente 2015-07-02 12:23:08 EDT

Description of problem:
currently the name/type of devices usable by Ceph on the OSDs nodes resides in a hieradata file [1] and defaults to /srv/data

this can be edited into a hash, like [2], but it can't be passed as parameter to heat directly; we should probably make it a parameter instead and remove it from hieradata

Comment 6 Mike Burns 2015-08-31 15:01:07 EDT

patch 211935 superseded by 

https://review.openstack.org/#/c/215013/
and
https://review.openstack.org/#/c/215116/

Comment 8 Dan Prince 2015-09-21 16:12:48 EDT

The commit message here describes nicely how to test this:

https://review.openstack.org/#/c/215599/3

If you create a custom environment as described in that commit message it should allow you to override the Ceph storage node device on each node.

Comment 9 Karthik Prabhakar 2015-09-21 16:20:42 EDT

Does this include the ability to specify the name of a journal device as well (especially when the journal needs to be on a different device from the Ceph data disk - for e.g., when one or more SSD's need to be used for journal)?

Comment 11 Luigi Toscano 2015-09-25 14:39:54 EDT

It is not possible to set specific values on Ceph nodes; the new upstream patch https://review.openstack.org/#/c/215599/ (found after a bit of debugging) addresses this problem. Moving to ASSIGNED for now.
