Change cluster name and storage location folder

Elastic Stack Elasticsearch
1

Hi all,

currently we have elastic stack's major version number in following fields:

cluster.name
path.data

Is it save to rename them, rename the folders or do I need some reindexing or other stuff?

Currently we are running a single instance, so no problem with other nodes.

I would like to get rid of version names to give less room for confusion after upgrading from 5.1.2 to 6.0.1

Thanks a lot.
Andreas

How did you install Elasticsearch and what OS are you on?

running on centos.
manual install by tar package.

How are you planning on upgrading?

Since I am originally the windows guy I build my own filestructure to have complete elastic stack in one place.

filestructure for ES as example:

[root@myserver elasticsearch]# ls -l
insgesamt 0
lrwxrwxrwx 1 logiweb_admin elasticsearch  19 15. Dez 15:47 current_elasticsearch -> elasticsearch-6.1.0
drwx------ 3 elasticsearch elasticsearch  18 21. Feb 2017  data
drwxr-xr-x 7 logiweb_admin elasticsearch 131 14. Feb 2017  elasticsearch-5.1.2
drwxr-xr-x 7 logiweb_admin elasticsearch 131 14. Aug 14:35 elasticsearch-5.5.2
drwxr-xr-x 7 logiweb_admin elasticsearch 131 10. Nov 19:42 elasticsearch-6.0.0
drwxr-xr-x 7 logiweb_admin elasticsearch 131  4. Dez 10:30 elasticsearch-6.0.1
drwxr-xr-x 7 logiweb_admin elasticsearch 131 12. Dez 13:34 elasticsearch-6.1.0
drwxr-xr-x 2 elasticsearch elasticsearch 199 18. Dez 09:07 log

The current version of elasticsearch is linked via current_elasticsearch.
The service is addressing the linked path current_elasticsearch.

so my data.path is currently: /usr/local/elk/elasticsearch/data/elk5

I would like to rename it to /usr/local/elk/elasticsearch/data/logicontrol_prod

cluster.name is currently set to logicontrol_5x. I would like to change it to logicontrol_prod.

my way of update is working so far, but I did not touch both parameters I asked for.

I would suggest using the repo's and installing with that method. Then you can either point the config at the path you want after you have renamed it.
