We've got a 15 shard cluster spread across 3 hosts. This morning our puppet software rebooted them all and afterwards the 'range' for each shard has become null in zookeeper. Is there any way to restore this value short of rebuilding a fresh index?
I've read various questions from people with a similar problem, although in those cases it is usually a single shard that has become null allowing them to infer what the value should be and manually fix it in ZK. In this case I have no idea what the ranges should be. This is our test cluster, and checking production I can see that the ranges don't appear to be predictable based on the shard number. I'm also not certain why it even occurred. Our test cluster only has a single replica per shard, so when a JVM is rebooted the cluster is unavailable... would that cause this? Production has 3 replicas so we can do rolling reboots.
