crontab on realtime linux

[paubine]

Hi,

I have to periodically check that a drive is mounted. I do it at startup and it work fine adding mountnfs and fstab in rc2-3-4, etc. BUT if the network drive die or reboot, I lost it and it never work again.

Doing "mount -a" in the command shell remount properly.

I would like to periodically do this command with crontab or other but I can't get cronie to work. When editing "crontab -e" and adding the command, it says "segmentaiton fault"

I would like to add "mount -a" every hour.

Let me know if you can help!

Thank you

Patrick

Hi paubine,

The issue you're running into is cronie taking too much stack and being killed off.

You can either raise the stack limit for the currently-running shell (and all children of the shell) by using ulimit -s unlimited and rerunning crontab -e

 ---or---

directly edit the crontab file (/etc/cron* files, currently the logrotate crontab file exists at /etc/cron.d/logrotate)

Thank you.

That worked, "crontab -e" created a file in /var/spool/cron/ called admin
