Trying to restart crontab service and getting no space left on device, however there are plenty of space in the server. Any help appreciated.
[root@at-app-dev-01 backup]# service crond restart
Redirecting to /bin/systemctl restart crond.service

Hi @aalurdratek,
Please try and run the following command on /
du -sh /
It might take some time to complete however I feel like there might be something not being shown by the df -h command.
Usual Causes
There are a couple of main causes here. Occasionally, a file will be deleted, but a process is still using it. Linux won’t release the storage associated with the file while the process is still running. You just need to find the process and restart it.
Try to locate the process.
sudo lsof / | grep deleted
The problematic process should be listed, then just restart it.
sudo systemctl restart service_name
If this doesn’t help, then I’ll recommend trying to reboot the droplet and see what happens.

Permanent solution: fs.inotify.max_user_watches=1048576 #just add to this line to /etc/sysctl.conf fixed the limit value permanently then do: sysctl -p
