Unassigned Shards and Upgrading Elasticsearch

Elastic Stack Elasticsearch
1

Hi,

Yesterday, I have added a new node to my ES cluster and after that some
of the shards started to remain unassigned. These shards are the
replicas of the shards on the new node. When I inspected the reason, I
found out that this new node has a different ES version. The new one is
1.3.4 and the older ones are 1.3.2.

Does this difference cause the problem? If I upgrade the older ones,
does this solves the issue?

I installed ES via apt-get in Ubuntu. If I upgrade the current nodes via
apt-get, does this cause problems with old indices?

Thanks,

Umutcan

You shouldn't run multiple versions unless you are upgrading, so it would
make sense to upgrade the other nodes ASAP.

The logs on your nodes should also shed some more light on the problem.
