Introduction

The default location of the influxDB data is /var/lib/influxdb.

Change the location

If you want to change the location, you’ll need to configure three folders to be in a different place. The changes should be done in the file /etc/influxdb/influxdb.conf

...
[meta]
  # Where the metadata/raft database is stored
  #dir = "/var/lib/influxdb/meta"
  dir = "/mnt/databases/influxdb/meta"
[data]
  # The directory where the TSM storage engine stores TSM files.
  #dir = "/var/lib/influxdb/data"
  dir = "/mnt/databases/influxdb/data"
  # The directory where the TSM storage engine stores WAL files.
  #wal-dir = "/var/lib/influxdb/wal"
  wal-dir = "/mnt/databases/influxdb/wal"

Storing data on NFS volume

I’m using this to store the data on a NFS share which is mounted automatically . If you want to keep your existing data, move the existing content of /var/lib/influxdb to the new location.

Make sure, that the new location is owned by influxdb user and group.
