[Plugin] CA User Scripts

[phyzical]

Hey all,

This might be a more generic unix question but is there an easy way to enable timestamps for all logs that a "userscript" would produce?

quick googling i can do things like pipe my commands into various things to achieve this but i was wondering if there was an easy "turn on for everything in unraid" or maybe just "turn on for user scripts logs"?

Thanks in advance!

Hello,

i hava a cron job problem.

I can't create a job with letters in day. This cron syntax 

40 7 * * Tue

sends an error in log "failed parsing crontab for user root: TUE" but 

40 7 * * 2 works

[Squid]

That's not a problem.  Slackware doesn't support TUE as a cron entry

[Dr.NAS]

Thanks, then I do not have to worry

[MrThistabut]

Would it be possible to have a way of grouping the scripts together? i have a bunch that run python scripts that id like to seperate from the rest if possible? 

 

thanks,

I want to backup my nextcloud and found a good script but had to change some parts for docker.

I already figured out how to set the maintenance mode and this works fine
 

docker exec --tty nextcloud sudo -u $webserverUser php $nextcloudDockerFileDir/occ maintenance:mode --off

 

So the script works so far, but i want to improve it.

But i was not able to figure out how i could check if the maintenance mode is on or off.
I think this is because of the "--tty" but other options work less.

 

Last week the backup worked fine but the maintenance mode was still on.
So i want to make a check at the end to switch it off if it is still on or maybe send a message to check the maintenance mode.

So how can i check the maintenance mode from outside the docker?

Hey all,

 

I'm migrating from and Ubuntu based server and I was trying to set back up one of my scripts.

 

It's a simple script that uses inotifywait to watch a folder and then emails (via mutt) any new pdf files to my kindle.

 

The inotify part works well enough but obviously mutt isn't part of unraid. Is there a command line alternative or even a simple docker container I could use to the same effect? (Short of running a linux vm lol)

If it's not already available within the NerdPack plugin, then you can ask for it to be added, or install (or build from source) a slackware package.

Quite a newbie so didn't know about Nerdpack - although mutt (or alt) doesn't seem to be included yet. I may request as you've suggested but I'll try and install one myself first I think as why not? haha

 

Thanks for the help!

never mind, I see you use the scheduling to add the cron for you...

My unraid box has a bit of a custom arrangement, where the GPU has 2x oversized fans - one blows on the GPU directly, and the other on the array drives and the GPU. The GPU controls one of the fans, and unraid controls the array fan.

 

I am trying to set up the ability to calculate and compare a required PWM value for the array drives and the GPU, and then decide which is higher and apply it to the array fan.

 

In my windows VM I use nvidia-smi with a timeout -t 5 loop running on a schedule to constantly update a txt file on the cache drive which unraid can read. This part seems to work ok, windows updates the txt file with the fan % value.

 

I have included in the array fan script (which I found on these forums) an arrangement which takes the percentage and converts it to PWM.

 

The issue is - it does not work with the file that is being dynamically updated by windows, but it does work with a static test file which was created by me in windows and is sitting in the exact same location!

 

I'm pulling my hair out on this, I can't work out why it is not working...any thoughts?

 

#!/bin/bash
# unraid_array_fan.sh v0.4
# v0.1  First try at it.
# v0.2: Made a small change so the fan speed on low doesn't fluctuate every time the script is run.
# v0.3: It will now enable fan speed change before trying to change it. I missed 
#	it at first because pwmconfig was doing it for me while I was testing the fan.
# v0.4: Corrected temp reading to "Temperature_Celsius" as my new Seagate drive
#	was returning two numbers with just "Temperature".
# A simple script to check for the highest hard disk temperatures in an array
# or backplane and then set the fan to an apropriate speed. Fan needs to be connected
# to motherboard with pwm support, not array.

# pwm1 is usually the cpu fan. You can "cat /sys/class/hwmon/hwmon0/device/fan1_input"

Are there any issues with overlapping jobs when scheduling?  i.e. ~4hr jobs run every hour

 

[TBKU]

I'm having trouble running a script that backs up my VMs.  For some reason, the log buttons are not available, and the script doesn't seem to run according to the CRON schedule I set in the GUI.

 

 

I also tried using a number 1-7 instead of the three letter day name.  I have other scripts running in the middle of the night for backing up shares that are working fine.  My only though is that this script is significantly more complicated then the others, but I'm not sure why that would matter.  If I run the script manually it works fine.

 

Any ideas?

Try getting rid of the spaces

Okay, I'll try that.  My other scripts have spaces and they are running on custom cron schedules just fine, though.

 

[Squid]

Sorry.  Didn't look closely enough.  It's the WED that's causing it to never run.  Change it to be 3

I tried it previous with 0 4 * * 1 and it never ran. I've changed it to 30 9 * * 3 and it seems to have kicked off correctly at 9:30 - still running.  I did change the name to all lowercase with no spaces, as suggested.

OK this seems to be fine when using the drop down schedules (scheduled Hourly), but as soon I use a custom cron schedule the script won't restart until after the running script finishes.

Is this a bug to be resolved, or is there a work around I need to use?

 

Currently wanting to run the script every 30 min with:

*/30 * * * *

I eventually found that I needed to run the command in the script as background task so the jobs could overlap. Sorted.

I ran user scripts for over a year now but it suddenly disappeared from the settings tab.

I removed it via the plugins tab and reinstalled it via CA but get the following message:

Delete the .txz from /config/plugins/user.scripts on the flash drive and try again

worked flawlessly, thank you!

My linuxfu is lacking...i wrote a script to start and stop a bunch of docker containers in a specific order.  When it's finished i would like it to close the pop up window. 

I tried exit and end to no avail.  I don't even know what that pop up window is called to Google it. 

 

What command should i use?
