No log file despite -l /path/to/file.log about hd-idle HOT 10 CLOSED

Hi @agcmartins

Could you please share the result of the command systemctl status hd-idle?
Also I'd be great if you could double check that the directory /home/USER (I guess obfuscated) really exists.

Thank you

from hd-idle.

Hi,
Directory exist, is my home folder, but I've change it to USER to post.

Sadly the log doesn't show long lines :/
Could you run this command and post the result? grep hd-idle /var/log/syslog

from hd-idle.

Sure, but sorry, before I saw you message I had to reboot it.
I've also installed hd-idle in my desktop to test, but leave the log as default (/var/log/hd-idle.log), than after while I have checked the folder and there is no file there too.

I can't tell why your log file is always empty. But not all is lost for you.

You can use grep hd-idle /var/log/syslog to monitor spinups and spindowns. That will give you the stats you need.

This is a sample of how the log file looks like:

date: 2020-04-01, time: 00:00:34, disk: sda, running: 671, stopped: 42523
date: 2020-04-01, time: 00:00:34, disk: sdb, running: 609, stopped: 9638
date: 2020-04-01, time: 00:00:34, disk: sdc, running: 611, stopped: 9576
date: 2020-04-01, time: 12:00:25, disk: sdb, running: 671, stopped: 42519
date: 2020-04-01, time: 12:01:26, disk: sdc, running: 671, stopped: 42581

hd-idle creates entries in the log file only on spinups. So I don't think it will be any useful for your use case to use the log file.

Hope this helps.

Thank you very much, I'll use that information. Do you have any advice about spin up events and hardware durability for external usb HD?
Regarding the log file, I've notice, that if I create an empty file using log name in directory, the program start to write lines on it. But it seems that if the file doesn't exit the program do not create it.
Best,

from hd-idle.

I had to re-test the scenario that you describe and I can confirm that the log file does get created if it doesn't previously exits.

Sorry that I can't help you further with this topic, but at least you got the data you were looking for.
Thank you

from hd-idle.

Hi all,
I know it's an old thread, but I also cannot see the log file despite the configuration file has been setup properly.
This is the result of: grep hd-idle /var/log/syslog

Anything I can do to help you track down the issue?

All right.
I understand now.
Thanks for your quick reply.
