Subject [jira] [Commented] (SOLR-8069) Leader Initiated Recovery can put the replica with the latest data into LIR and a shard will have no leader even on restart.

Mark Miller commented on SOLR-8069:
-----------------------------------

bq.  one way I see this 

That really seems the same as just getting the context earlier in the request.

Given the different ways LIR might be started and used, it really seemed simpler to try and
localize the changes rather than tie them more into the request lifecycle.

> I've seen this twice now. Need to work on a test.
> When some issues hit all the replicas at once, you can end up in a situation where the
rightful leader was put or put itself into LIR. Even on restart, this rightful leader won't
take leadership and you have to manually clear the LIR nodes.
> It seems that if all the replicas participate in election on startup, LIR should just
be cleared.
