Hi,
am struggling around with creating multiple collections on a 4 instances
SolrCloud
setup:
I have 4 virtual OpenVZ instances, where I have installed SolrCloud on each
and
on one is also a standalone Zookeeper running.
Loading the Solr configuration into ZK works fine.
Then I startup the 4 instances and everything is also running smoothly.
After that I am adding one core with the name e.g. '123'.
This core is correctly visible on the instance I have used for creating it.
it maps like
'123' ----> shard1 -----> virtual-instance-1
After that I am creating a core with the same name '123' on the second
instance and it
creates it, but an exception is thrown after some while and the cluster
state of
the newly created core goes to 'recovering'
*"123":{"shard1":{
"virtual-instance-1:8983_solr_123":{
"shard":"shard1",
"roles":null,
"leader":"true",
"state":"active",
"core":"123",
"collection":"123",
"node_name":"virtual-instance-1:8983_solr",
"base_url":"http://virtual-instance-1:8983/solr"},
"**virtual-instance-2**:8983_solr_123":{*
* "shard":"shard1",
"roles":null,
"state":"recovering",
"core":"123",
"collection":"123",
"node_name":"virtual-instance-2:8983_solr",
"base_url":"http://virtual-instance-2:8983/solr"}}},*
The exception throws is on the first virtual instance:

I've thought that currently the only way to create multiple cores in solr
cloud which are distributed over shards
is to create cores with the same name on each single solr instance?
Thanks & regards
Daniel
