Description Michele Baldessari 2018-07-18 13:33:18 UTC

Description of problem:
When creating bundles (rabbit/galera/redis) with pcmk-1.1.19 code inside against a pcmk-1.1.18 cluster, we will experience crm_node -n hanging, because when pcs creates the bundle it will invoke the meta-data function. Doing so in this specific configuration will invoke crm_node -n which will hang.

By not invoking crm_node -n, everything is fine.

This is due to the newly introduced CRM_OP_NODE_INFO call and this very specific upgrade path.

Fix is here: https://github.com/ClusterLabs/resource-agents/pull/1173/
