[Need Help] Reporting on external SSD

[raviwarrier]

This is similar to #75 but since that was closed without resolution...

This used to work before, but somehow I can't make it work after I reformatted+reinstalled my pi.

Here an image of the result of blkid:

My external SSD is mounted as '/dev/sda1' is accessed by '/srv/dev-disk-by-uuid-E4FAC652FAC62122/'.

I have tried everything '/dev/sd1', '/dev/disk/by-uuid/E4FAC652FAC62122' (i don't know, but I saw this on Webmin's dashboard) and '/srv/dev-disk-by-uuid-E4FAC652FAC62122/', but everything gives out 0% or Unavailable or Unknown.

I also have a problem with my /boot (used to work before the clean install) and tried permutations of that as well.

Please help. Also, you had asked for this in #75 (> Can you send me the config that's send to mqtt (homeassistant/sensor/{device name}/disk_use{name of disk}) and also the resulting json that's send as value (system-sensors/sensor/{device name}/state)) and I would gladly give it only if I understood what that was and how to get it.

Thanks.

Do you get any error and could you send your config?

[raviwarrier]

I get no error when I run the service.

pi@rwpi:~ $ cat system_sensors/src/settings.yaml mqtt: hostname: 192.168.1.14 port: 1883 #defaults to 1883 user: password: **** deviceName: RWPI client_id: RWPI_SS timezone: Asia/Kolkata update_interval: 60 #Defaults to 60 sensors: temperature: true clock_speed: true disk_use: true memory_use: true cpu_usage: true load_1m: true load_5m: true load_15m: true net_tx: true net_rx: true swap_usage: true power_status: true last_boot: true hostname: true host_ip: true host_os: true host_arch: true last_message: true updates: true wifi_strength: true wifi_ssid: true external_drives:

Only add mounted drives here, e.g.:

# Drive1: /media/storage
SSD: /srv/dev-disk-by-uuid-E4FAC652FAC62122/
SDCard: /boot/

I hope I sent you the correct info.

Edit: the spacing under external_drives: is as per your example, but it's not showing up here.

Here's the screenshot from HA for the SSD:

Could you format the config so I can see that is right intended (https://docs.github.com/en/github/writing-on-github/working-with-advanced-formatting/creating-and-highlighting-code-blocks)

What do you get when you run sudo systemctl status system_sensors

[raviwarrier]

trying. if this doesn't work, will upload the yaml file and share the link

What do you get when you run sudo systemctl status system_sensors

Nothing. Just the next line as captured in the image.

[Sennevds]

that's the start command not the status command

What do you get when you run sudo systemctl status system_sensors

Nothing. Just the next line as captured in the image.

That's start not status

[raviwarrier]

My bad.

Okay could you try following for me enter following

python3
import psutil
psutil.disk_usage('/srv/dev-disk-by-uuid-E4FAC652FAC62122/')
exit()

what output do you get?

[raviwarrier]

When I went through your code, I saw the psutil stuff and wanted to run it to do this very test, but didn't know how. Learned something new today. Thanks.

[raviwarrier]

I did the same for /boot and got the following:

>>> psutil.disk_usage('/boot/')
sdiskusage(total=264289280, used=50422784, free=213866496, percent=19.1)

[Sennevds]

okay could you do following thing:

sudo systemctl stop system_sensors
cd system_sensors/src
python3 system_sensors.py settings.yaml

let that run and see if you get the right value in HASS

[raviwarrier]

It worked for SSD but not for boot. Boot disk usage entity is still disabled.

Edit/Update: It worked for both.

Now what should I do? Can I Ctrl+C the python command? It's late here (perhaps there as well). Let me know what you need me to do next and I'll do it tomorrow morning when I wake up.

Cheers and goodnight.

[Sennevds]

Just Ctrl + c and restart the service by following command: sudo systemctl start system_sensors

[raviwarrier]

Okay. Done. Will check tomorrow morning and report back.

[raviwarrier]

I realized I didn't get back to you. It worked fine, so thank you. I just had to reinstall my RPI (damn homeassistant keeps mucking up) and installed (and even followed the steps we did above), but my SSD shows 0%. Will try it out again tomorrow (might have missed a step above). Thanks for all your help.

Edit: got it working. thanks a ton again. closing this request.
