Full Copy during cluster restarts

[Paddy Krishnamoorthy <kp...@gmail.com>]

We are running a solr 4.10.2 cluster with dozens of nodes. When ever we
restart the cluster we see that 2-3 nodes goes in to a fullCopy mode, which
takes for ever to recover. Because of the recovery our entire cluster runs
very slow and eventually becomes unresponsive.

Any thoughts?


Thanks
Paddy

The most likely cause is that you were indexing when the nodes were
down and/or have not issued a hard commit. If you stop indexing _and_
issue a hard commit (openSearcher=true or false doesn't matter), then
the nodes should come back up without having to replicate the index.

This might help:
