Option to set nice value?

[zz0rk]

I am running ppbd/ppbwd LOCAL (UPS monitoring daemon) on my snapraid server. My REMOTE server running ppbd/ppbwd consistently loses its connection to LOCAL and initiates shutdown on REMOTE. This happens consistently about one hour into running the script. I ran the script with 'nice -n 13' but it made no difference. Do I need to modifiy the script iteself? Curious to know if others had similar issues with UPS. Thank you

I have no idea what you're referring to, what is the nice 13 option?

Sorry, that wasn't very clear. I was referring to the 'nice' Linux command.
https://linux.die.net/man/1/nice

I've since found some more information and the recommendation is to try 'ionice'.
https://www.snapraid.it/faq

I added 'ionice -c 3' to my crontab.
0 1 * * 1 /usr/bin/ionice -c 3 /root/scripts/snapraid-aio-script-3.3.2/snapraid-aio-script.sh

The reason why I posted here is because I wasn't sure if 'nice' or in this case 'ionice' has any influence on the commands executed in the script, so I was wondering if there's a solution for that. I am not a programmer, so I didn't want to get creative modifying the script.

I am going to report back if my crontab mod made a difference.

Thanks for your reply!

Ok, so running the script itself with 'ionice' didn't make a difference. Would you mind providing some guidance what part of the script I need to modify? The official snapraid FAQ suggests 'ionice -c 3 snapraid sync', but I don't know how to achieve that.
Thank you

All right, to make such change you could try to edit the CONFIG file, find the line:

SNAPRAID_BIN="/usr/bin/snapraid"
change it to
SNAPRAID_BIN="ionice -c 3 /usr/bin/snapraid"

Not guaranteed to work since I haven't tested this.

Great, I will give this a whirl. I won't be able to test until after 09/01, but I will report back. Thank you for taking the time to get back to me. Cheers
