The yellow restart gate carried in the previous patch lets a permanently
yellow cluster through, and with three or more nodes packages/apps/opensearch
turns drainDataNodes on. The restart then reaches PreparePodForDelete, which
excludes the candidate from allocation before it can know whether the drain
will finish. On the cluster that made the gate wait it never finishes: a shard
on that node has nowhere else to go, which is the same condition holding the
cluster yellow. The exclusion is withdrawn only after a pod is really deleted,
so a data node stays out of allocation for as long as the restart is stuck,
shedding its shards onto the rest of the cluster and buying nothing.
Ask the allocator before excluding anything, and only while nothing is moving,
so a drain that is making progress costs nothing. A started shard answering
can_move_to_other_node: no means the drain cannot finish, and then no exclusion
is written and one left by an earlier pass is withdrawn. The two-data-node path
keeps its behaviour, because it never waits for a full drain.
Checking after the fact instead would flap: the next reconcile, ten seconds
later, would exclude the node again.
Upstream as opensearch-project/opensearch-k8s-operator#1585, fixed there by
#1586; the patch goes away with the first release carrying it.
Backport: the Dockerfile header keeps release-1.6's trace paragraph,
placed between the new ones as on main.
