The RunningSnapshotIT upgrade test adds shutdown marker to all nodes and removed them once all nodes are upgraded. If an index gets created in a mixed cluster, for example by ILM or deprecation messages, the index cannot be allocated because all nodes are shutting down. Since the cluster ready check between node upgrades expects a yellow cluster, the unassigned index prevents the ready check to succeed and eventually timeout. This PR fixes it by removing shutdown marker for the 1st upgrade node to allow it hosting new indices. Resolves: elastic#129644 Resolves: elastic#129645 Resolves: elastic#129646

Those two shards remain on their initial nodes. They are not unassigned because they are not new shards. The snapshot cannot complete because:
So yeah the snapshot can completely only when all nodes are upgraded and remaining shutdown marker removed. |
