Hi Olivier,

Can you look at the collections to see if there are leader initiated
recovery nodes in the ZooKeeper tree? Go into the Solr Admin UI ->
Cloud panel -> Tree view and drill into one of the collections that's
not recovering /collections/<collection>/leader_initiated_recovery/

You could try deleting the znodes for one of the shards under that and
see if that shard recovers.

Let me know what shakes out as there still may be a bug in this area
of the recovery logic.
