OK, so there's your problem... you're not running the script, you're marking it as executable (chmod +x)

First, in a shell, run /usr/local/bin/dkbox1.sh

See if there's any output (and if it beeps).

If it's OK, change the cron task command to /usr/local/bin/dkbox1.sh

May I ask how should I run in the shell /usr/local/bin/dkbox1.sh ?

Then there's something wrong with the script.

Are you sure that you changed only the line I mentioned to you and nothing else from the original script? It works when I run it.

Are you running CORE or SCALE?

OK, well that's obviously not the same as needs to be in the file...

You're missing the first line and the first character of the second line.

Code:

#!/usr/local/bin/bash
if zpool status -v | grep -q DEGRADED; then
echo Degraded Found
logger buzzerAlarm a pool is DEGRADED SOUND MB BUZZER
# run alarm 1800 times every .1 sec = sounds beeper for 180s / 3min exactly
    for i in {1..1800}
    do
    sleep 0.1
    /usr/bin/printf "\007" > /dev/ttyv6
    done
# send to local and remote log
logger buzzerAlarm script JUST FINISHED fireing for 3min bc pool DEGRADED

Is this correct?

bash: /usr/local/bin/dkbox23.sh: Permission denied

so you created a new file...

You need to allow the new file to run:

chmod +x /usr/local/bin/dkbox23.sh

Then you can run it.

The script does work, but there is no buzzer since my pool was downgraded. don't know what's wrong

 

[sretalla]

So, let me summarize:

Your pool status shows degraded zpool status

You updated the script correctly and it generates no errors... but what does it output? it must say either Degraded found or phrase not found

If it outputs "Degraded found", I expect you should hear the beeping

Now the script can already run, I don't know why every time I create a script file, the pasted content always lacks the first letter of the first line and the second line. But now the script will only beep once every 1 minute after running, and will not make continuous sound.

 

[sretalla]

When you run it at the shell, does it beep continuously or just once? (I'm not sure if you're saying it works differently when it's a cron task)

Run the script content directly in SHELL, it can make continuous sound for 3 minutes

 

[sretalla]

Try changing the cron task to run /bin/bash /usr/local/bin/dkbox23.sh

 

[sretalla]

If that script is going to run every minute and last 3 minutes, you are going to have problems though.
