- Plesk Onyx for Linux
When adding/removing a service node, the process gets stuck with the error message:
PLESK_INFO: Failed API request: The extension plesk-multi-server-node is not installed.
All new tasks have the New status on the Tasks page on the management node.
There are no clear error messages in /var/log/plesk/panel.log on the management node.
The "crond" service is not running on the management node:
# service crond status
Redirecting to /bin/systemctl status crond.service
● crond.service - Command Scheduler
Loaded: loaded (/usr/lib/systemd/system/crond.service; enabled; vendor preset: enabled)
Active: inactive (dead)
The service "crond" is not running on the management node, which is required to run tasks.
Connect to the management node via SSH.
Start the crond service:
# service crond start
In Plesk remove the stuck service node process: go to Nodes > select the stuck service node > click Remove.
Re-add the node.
