SOLR cloud (5.2.1) recovery
hello, i'am a bit confused about how solr cloud recovery is supposed to work exactly in the case of loosing a single node completely. My 600 collections are created with numShards=3replicationFactor=3maxShardsPerNode=3 However, how do i configure a new node to take the place of the dead node, or if accidentally i delete the data dir ? I bring up a new node which is completely empty (empty data dir), install solr, and connect it to zookeeper.Is it supposed to work automatically from there? All my shards/replicas on this node as down (i suppose because there is no cores in data dir). Do I need to recreate the cores first? Can i copy/paste data directory from another node to this one ? I think no because i should rename all variables in core.properties which are dedicated for each node (like name or coreNodeName) thanks, Olivier Damiot
Leader election
Hello everybody, I use solr 5.2.1 and am having a big problem. I have about 1200 collections, 3 shards, replicationfactor = 3, MaxShardPerNode=3. I have 3 boxes of 64G (32 JVM). I have no problems with the creation of collection or indexing, but when I lose a node (VMY full or kill) and I restart, all my collections are down. I look in the logs I can see problems of leader election, eg: - Checking if I (core = test339_shard1_replica1, coreNodeName = core_node5) shoulds try and be the leader. - Cloud says we are still state leader. I feel that all server pass the buck! I do not understand this error especially as if I read the mailing list I have the impression that this bug is solved long ago. what should I do to start my collections properly? Is someone could help me ? thank you a lot Olivier
