Bash script not creating file from crontab

Question

I have already tried half of askubuntu but still not succeeding. I got the following shell script:

#!/bin/bash
echo "test" > "/mnt/ssd/test.txt"
echo "test"

And the following crontab -e line:

* * * * * /mnt/ssd/test.sh > /mnt/ssd/cron.log

When I add a line to the cron.log file manually, it will be empty each new minute what tells me the cron is being fired.

I also tried the following cronjob:

* * * * * env > /mnt/ssd/env.output

This gave me these values:

LANGUAGE=nl_NL.UTF-8
HOME=/home/pi
LOGNAME=pi
PATH=/usr/bin:/bin
LANG=nl_NL.UTF-8
SHELL=/bin/sh
LC_ALL=nl_NL.UTF-8
PWD=/home/pi

It again tells me the cron is working and the SHELL is correct right?

I tried this cron as well:

* * * * * PATH=/bin:/sbin:/usr/bin:/usr/sbin /mnt/ssd/test.sh > /mnt/ssd/cron.log

Neither this writes anything to the cron.log file or is creating the test.txt file.

I am kinda confused. If my PATH is wrong am I trying to correct this in the right manner or is something else incorrect?

EDIT: thanks to @steeldrive it was found that the drive this script was located on was mounted with noexec type. Meaning a bash file can not normally be executed. Placing 'bash' in front of the command made it work. The command now looks like:

* * * * * bash /mnt/ssd/test.sh > /mnt/ssd/cron.log 2>&1

the 2>&1 is added so errors would also be outputted to the log file.

Answer 1

Ok so, based on the input given by @steeldriver, we managed to obtain a solution.

The bash script is located on a mount which has been mounted by the noexec type. Meaning the bash files cannot be executed straightforward. This was found using the command:

mount | grep ssd

The solution however is simple: add bash in front of the crontab -e command:

* * * * * bash /mnt/ssd/test.sh > /mnt/ssd/cron.log 2>&1

The 2>&1 part is added in this line as well so the error logs are also placed inside the cron.log file.
