How long for autoAddReplica?

I added a new node an shut down a node with a shard replica on it. It has been an hour and I don’t see any activity toward making a new replica.

The new node and the one I shut down are both 6.4. The rest of the 16-node cluster is 6.2.1.

Not sure what you mean by migrating and replacing nodes, but these two new
actions on the Collections API as of Solr 6.2 may be of use:

   -
   https://cwiki.apache.org/confluence/display/solr/Collections+API#CollectionsAPI-REPLACENODE:MoveAllReplicasinaNodetoAnother
   -
   https://cwiki.apache.org/confluence/display/solr/Collections+API#CollectionsAPI-DELETENODE:DeleteReplicasinaNode

bq: I don’t see a way to add replicas through the UI, so migrating by
replacing nodes is going to be a bother

There's a lot of improvements in the admin UI for SolrCloud that I'd
love to see. Drag/drop replicas would be really cool for instance.

At present though using
ADDREPLICA/wait-for-new-replica-to-be-active/DELETEREPLICA through the
collections API is what's available.

Best,
Erick

Oh, missed that limitation.

Seems like something that would be very handy in all installations. I don’t see a way to add replicas through the UI, so migrating by replacing nodes is going to be a bother.

Hi,

are you using HDFS? According to the documentation the feature should be 
only available if you are using HDFS. For me it did however also fail on 
that. See the thread "Solr on HDFS: AutoAddReplica does not add a 
replica" from about two weeks ago.

regards,
Hendrik
