Change data directory

InfluxDB 2
1

Hey Guys,

i am trying to change the data directory for my new set up InfluxDB.

I changed the Path on the InfluxDB.config to my preferences.
And tried

sudo chown influxdb:influxdb /media/4tb/influxdb/

but I get the following error

chown: changing ownership of ‘/media/4tb/influxdb/’: Operation not permitted

any help with that ?
im running on ubuntu 18.04 but I a linux noob :slight_smile:

Thanks!

Is that 4tb device:

a) mounted read-only

b) not an EXTn file system?

its mounted read / write.

Its an exfat filesystem.

There’s your answer, then.

You can’t change the ownership on an exfat system.

The only way I can think to achieve what you want is to mount it as the
influxdb user, not as root (or anybody else).

if you plan on using the drive exclusively with Linux systems then you can format the drive as an ext4 volume and try again

alright I try that thanks guys

I used ext4 and it works now but when I try to start the dbservice I get the following:

    timo@fileserver:~$ sudo systemctl status influxdb

I’ll have to step back and let someone else respond regarding this, as I’ve
never used systemd for managing services.

Hello,

I’m currently using the configuration below, and I haven’t had any problems so far, I hope it helps you

My service lib/systemd/system/influxdb2.service

[Unit]
Description=INFLUXDB2

[Service]
Type=simple
ExecStart=/bin/bash /var/InfluxDB/run.sh

[Install]
WantedBy=multi-user.target

and inside the bash script (/var/InfluxDB/run.sh) I added the parameters that I need

/usr/local/bin/influxd --http-bind-address=:8086
