Roman Puchkovskiy updated IGNITE-22913:
---------------------------------------
Description:
After a Metastorage group (MG) was repaired as described in IGNITE-22889, nodes
that did not take part in the repair but returned later and were migrated to
the repaired cluster might have Metastorage data inconsistent with the leader
(that is, it has diverged). We need to detect such nodes and disallow them to
join the cluster.
