Create users

 CREATE USER "dl2sba" WITH PASSWORD 'password' WITH ALL PRIVILEGES
 CREATE USER "node-red" WITH PASSWORD 'password'
 GRANT ALL ON "iot" TO "node-red"

Check health of SSD

sudo smartctl -xaH /dev/sda
sudo badblocks -v /dev/sda

Relocate existing InfluxDB

Stop Daemon

sudo service influxdb stop

Edit config file

sudo vi /etc/influxdb/influxdb.conf

 [meta]
 # Where the metadata/raft database is stored
 # dir = "/var/lib/influxdb/meta"
 dir = "/influx-db/influxdb/meta"
 
 [data]
 # Controls if this node holds time series data shards in the cluster
 enabled = true
 # dir = "/var/lib/influxdb/data"
 dir = "/influx-db/influxdb/data"
 # These are the WAL settings for the storage engine >= 0.9.3
 # wal-dir = "/var/lib/influxdb/wal"
 wal-dir = "/influx-db/influxdb/wal"

Copy directory content

sudo cp -R --preserve=all /var/lib/influxdb /influx-db
sudo mv /var/lib/influxdb /var/lib/influxdb-old

Restart daemon
