shard merged into a another shard as replica
I am not sure what happened, I updated merchant collection and then
restarted all the solr machines.
This is what I see right now: http://i.imgur.com/4bYuhaq.png
merchant collection looks fine. But deals and prodinfo collections should
have a total of 3 shards. But someone shard1 has converted to replica of
shard2.
This is running in production, so how can I fix it without dumping the
whole zk data?

Thanks Mark. I tried updating clusterstate manually, things went haywire J.
So to fix it, had to take 30secs-1min downtime where I stopped solr and zk,
deleted "/zookeeper_data/version-2" directory and restarted everything
again.
I have auotmated these commands via fabric, so was easily able to recover
from the downtime.
Thanks,

Hopefully an issue that has been fixed then. We should look into that.
You should be able to fix it by directly modifying the clusterstate.json in ZooKeeper. Remember to back it up first!
There are a variety of tools you can use to work with ZooKeeper - I like the eclipse plug-in that you can google for.
Many, many SolrCloud bug fixes (we are about to release 4.6.1) since 4.4, so you might consider an upgrade if possible at some point soon.
