hat you know the replica you are deleting
isn't 'down' intentionally, but you want do delete it anyway.

Yes, it's the intended behavior. The whole point of the
onlyIfDown flag was as a safety valve for those
who wanted to be cautious and guard against typos
and the like.
If you specify onlyIfDown=false and the node still
isn't removed from ZK, it's not right.

What I'm doing is to simulate host crashed situation.
Consider this, a host is not connected to the cluster.
So, if a host crashed, I can not delete the down replicas by using
onlyIfDown='true'.
But in solr admin ui, it shows down for these replicas.
And whiteout "onlyIfDown", it still show a fai
Thanks for taking the time for the detailed response. I completely get what
you are saying. Makes sense.

Well, "kill -9" just makes it harder. The original question
was whether a replica being "active" was a bug, and it's
not when you kill -9; the Solr node has no chance to

Pardon me for hijacking the thread, but I'm curious about something you

the pain of using zookeeper and creating replicas was so that the system

First of all, killing with -9 is A Very Bad Idea. You can
leave write lock files laying around. You can leave
the state in an "interesting" place. You haven't given
Solr a chance to tell Zookeeper that it's going away.
(which would set the state to "down"). In short
when you do this you have to dea
