Hello,

We have an EC2 inside Autoscaling Group (1 instance at a time) with Cloud\_init / Cfn\_init script to build up.

We mount an ElasticFileSystem where we have **data** and **plugins** directories to have persistent volume even if EC2 is recreated.  
**grafana.ini** config file is changed before grafana-server is started during user data script execution.

Since yesterday we were using a 7.1.something version, and everything was working fine, Datasources, Dashboards were still present when recreated or updated.

Yesterday, version 7.4 latest with:

> yum install -y grafana

And it seems that now, grafana.db file is recreated and I need to manually recreate Datasources and import Dashboards as json (fortunately we have them stored on a gitlab project).

I would avoid having to use the provisioning if having a persistent volume is sufficient.

Any ideas what could be causing this behaviour ?

Thanks a lot

Hello. An EC2 is a VM on AWS cloud.  
Elastic Filesystem is a volume (than auto extend upon needs) and can be mounted on one or more EC2s.  
Changing data and plugin folder I was able to define once datasources and dashboards (in DB I think) located in this mounted volume.  
And then when a new EC2 is created (change of config/crash/scaling) it was able to display the previously configured datasources and dashboards.

Since 7.4 it is not working anymore ☹  
I did not read anything in the update to 7.4 about this.  
I will try to check the release note or change log…

Thanks
