 # Trouble-Shooting
 
+Get a list of indides:
+
+```
+curl "http://127.0.0.1:9200/_cat/indices?v"
+```
+
 If an index went read-only:
 
 ```
 curl -X PUT http://127.0.0.1:9200/[INDEX]/_settings -H 'Content-Type: application/json' -d '{"index.blocks.read_only_allow_delete":null}'
 ```
+
+Or use the prepared script `elasticsearch-remove-readonly` for this.
