I want to reindex an index,and then _aliases.
after execute _reindex,it looks ok,but after execute _aliases,all the index can not write, and query is timeout.include the other indexes in the cluster. so I rollback,it recovery
here is the monitoring screenshot
22:00 start _reindex, 22:05 finished
22:06 start _aliases,and error occurred.looks like the cluster is not available.all the other indexes in the cluster also can not work.
the new index I didn't set refresh_interval,maybe its the reason why disk capacity is rising but document count is still zero when reindex.
