Removed nodes still visible as gone in Solrcloud graph

Hi,

On a node, I accidentally changed the SOLR_HOST value from uppercase to
lowercase and I restarted the node. After I fixed the error, I restarted
again the node but the node name in lowercase is still visible as "gone".
How to definitively remove a gone node from the Solrcloud graph ?

Regards.

Dominique

Hi,

I reply to myself.

The solution is to edit the state.json fie for all impacted collections.


   - Stop all Solr nodes


   - Download state.json file from ZK for collection "xxxxxx"

# server/scripts/cloud-scripts/zkcli.sh -z "xxx.xxx.xxx.xxx:2181" -cmd
getfile /collections/xxxxxx/state.json /tmp/xxxx-state-local.json


   - Edit the downloaded state.json and save it


   - Remove collection state.json from ZK

# server/scripts/cloud-scripts/zkcli.sh -z "xxx.xxx.xxx.xxx:2181" -cmd
clear /collections/xxxxxx/state.json


   - Upload modified state.json to ZK

# server/scripts/cloud-scripts/zkcli.sh -z "xxx.xxx.xxx.xxx:2181" -cmd
putfile /collections/xxxxxx/state.json /tmp/xxxx-state-local.json


   - Start all Solr nodes
