My cluster used to had 2 node,  
this node as : `master`  
another node as : `data-1`.  
I decide to make it as single node again so I shut `data-1`.  
I reconfigure `elasticsearch.yml` on `master` to make it as default ,  
but when I try to rune the previously `master` node it returning

```auto
{"statusCode":503,"error":"Service Unavailable","message":"License is not available."}

```

my log  
`journalctl --unit elasticsearch`

```auto

I've tried some solution here [solutions from github](https://github.com/elastic/elasticsearch/issues/51361), [https://discuss.elastic.co/t/elasticsearch-wont-start-after-7-9-1-to-7-9-2-upgrade/249878/2](https://discuss.elastic.co/t/elasticsearch-wont-start-after-7-9-1-to-7-9-2-upgrade/249878/2)

```auto
8-13:-XX:+UseConcMarkSweepGC
8-13:-XX:CMSInitiatingOccupancyFraction=75
8-13:-XX:+UseCMSInitiatingOccupancyOnly

```

not working,

```auto
-XX:+UseConcMarkSweepGC
-XX:CMSInitiatingOccupancyFraction=75
-XX:+UseCMSInitiatingOccupancyOnly

```

not working

```auto
#-XX:+UseConcMarkSweepGC
#-XX:CMSInitiatingOccupancyFraction=75
#-XX:+UseCMSInitiatingOccupancyOnly

```

not working either

any suggestion will be appreciated

How exactly did you remove the other node, can you provide more details on that?

Hi @warkolm , sure.  
I just shut the elasticsearch service on the node I want to remove.  
then return the elasticsearch.yml of the node I want to keep as default.
