InfluxDB configuration when using a storage extension

[star_board]

Hello!

I am currently using InfluxDB for data storage. I have an SD card mounted as a memory extension, and in the InfluxDB configuration file (influxdb/config.yaml), I have specified the following paths:

However, after some time of storing data, I noticed that my ctrlX internal storage became full, while the memory card remained empty:

Once I deleted the respective InfluxDB bucket, the internal memory returned to normal:

This indicates that the InfluxDB data is being stored on the internal memory instead of the memory card. Is this the expected behavior?

Thanks in advance! 😊

Hi @star_board 

your yaml should look like this:

Which version are you using?

bolt-path: /media/mmcblk1p1/influxdb/bolt-path

engine-path: /media/mmcblk1p1/influxdb/engine

As suggested by @TheCodeCaptain , please provide your configuration: apps and versions and which OS version you are using

Does this means that I can't storage data on the SD card if I have it mounted as removable medium on the ctrlX?

I am currently using Telegraf to write metrics to the InfluxDB App.
I am using LTS Release 2.6:

Hello, 

I need also the "system apps" version if possible if you can do a system report would be perfect.

It is definitely possible, we have many running since a lot of time collecting many data. Follow this guide and use the memory as "Removable Media" for now, we investigate the root cause of your setup here there is the guide:

With your setup you can collect also realtime data:

Here are all the applications installed on the device:

I have followed the guide and set the memory as "Removable Media," but I am not sure if data is being saved to the SD card. How can I verify this?

[MauroRiboniMX]

Have you followed the guide setting the memory in the yaml?

[star_board]

Yes!

Is there a way to actually verify where data is beeing written to?

[MauroRiboniMX]

Is mmcblk1p1 your disk name? Than it is correct. Disk explore feature comes the next release

[star_board]

Yes, that's the name! 

[MauroRiboniMX]

Then is perfect

Just to clarify, as of now, there isn't a method to check if data is truly being saved to the SD card?

The alternatives I found were:

• Using SSH to monitor the utilized storage space on the SD card, and periodically comparing it to see if it has increased. 
  
• Monitor the DL node: system/resources/storage

Hello, 

The problem is strictly related to the device used toghether with "EXTENSION OF INTERNAL MEMORY". Any other usage is not affected. 
We are working on a fix. I update you as soon as we have a schedule for fix 😁
