Just to close the topic.
What did i do :
Stopping influxdb
sudo systemctl stop influxdb.service
Copy the data ( On ubuntu, default location of data is : /var/lib/influxdb )
sudo cp /var/lib/influxdb/ /media/hd-1TB/ -R
Change owner & group for --> influxdb:
sudo chown influxdb:influxbd /media/hd-1TB/influxdb/ -R
Modify the configuration file ( location → /etc/influxdb/config.toml)
#bolt-path = "/var/lib/influxdb/influxd.bolt"
bolt-path = "/media/hd-1TB/influxdb/influxd.bolt"
#engine-path = "/var/lib/influxdb/engine"
engine-path = "/media/hd-1TB/influxdb/engine"
Start the influxdb service :
sudo systemctl start influxdb.service
Check datas arriving in the new folder :
airvb@airvb-serveur:/var/lib/influxdb$ sudo du -s /media/hd-1TB/influxdb/
**9153596** /media/hd-1TB/influxdb/
airvb@airvb-serveur:/var/lib/influxdb$ sudo du -s /media/hd-1TB/influxdb/
**9153624** /media/hd-1TB/influxdb/
airvb@airvb-serveur:/var/lib/influxdb$
Delete old folder
sudo rm /var/lib/influxdb/ -R
Thanks again for yr help.
