As you come from a migration, I assume you can loose all your logs.
If this is the case, and your leader node is 1, execute the following procedure in the leader node 1.
-
install another Loki instance in Node 1
add-module loki 1Here I assume the new instance is
loki2. -
transform the new instance in the active one
redis-cli set cluster/default_instance/loki loki2 redis-cli publish cluster/event/default-instance-changed '{"instance":"loki","previous":"loki1","current":"loki2"}' -
remove the old Loki instance (optional)
remove-module --no-preserve --force loki1
