[UNTESTED] ensure mongodb is installed/configured before clustering (bsc#944417) #19
Conversation

Actually, it's not perfect as, as discussed on Friday, this will not work if the cluster has 4 nodes (since the mongodb bit will only run on 3 nodes, and the sync mark will block forever). I don't have a good idea on how to fix this :/ |
|
@vuntz Simple - we should add Crowbar validation to prevent clusters with even numbers of nodes > 2. |
|
@vuntz How about something like this? crowbar/crowbar-ha#18 |
| # will have all the required packages installed and configured before | ||
| # we create the pacemaker resources | ||
| crowbar_pacemaker_sync_mark "sync-mongodb_before_ha" | ||
|

Can you move it inside the if ha_enabled block?

Technically that's not necessary since the sync_mark primitives are a nop if there is no cluster, but yeah, I agree that's nicer - done.
Just like with all other HA OpenStack resources, we need to prevent the resources being configured in Pacemaker before we know that all nodes have the necessary packages installed and correctly configured.

@vuntz Thoughts on what we should do with this one? |

@vuntz Agreed. |

What's the story with this PR? It's quite old, and no activity on it for a long time? If it's no longer valid, please close it. Thanks. |
