Inventory cleanup cron job is not running

Question

The cron job at magento/module-inventory-reservations/etc/crontab.xml does not show up in the general pool in the admin backend. It does not show up in cron_schedule table. It does not run. All other cron jobs are running.

I have run 'bin/magento cron:run', 'update/cron.php' and 'bin/magento setup:cron:run' successfully.

Here is the crontab.xml, this is the default

            <schedule>0 0 * * *</schedule>
        </job>
    </group>
</config>

cron is installed correctly. It shows magento cron if i run

sudo systemctl status cron.service

It also shows magento cron if i run

crontab -l

bin/magento cron:install returns Crontab has already been generated and saved.

Cron is running. The problem is "inventory_cleanup_reservations" is not executed!

How do I enable this specific cron job?
How do I run this?

Answer 1

As a workaround, until you figure out why your crons are not running, you can use https://github.com/netz98/n98-magerun2 tool to run the cronjob on demand.

To execute the cronjob, use the command:

./n98-magerun2.phar sys:cron:run inventory_cleanup_reservations

Answer 2

Some step to verify cron job in Linux:

1, Check cron job is running

sudo systemctl status cron.service

2, Add Magento to crontab

php bin/magento cron:install

3, Check crontab has added Magento cron

crontab -l

After 00:00 daily use can go to check it.

So If you want to quickly test this cron you should change it to

* * * * *

And flush cache
