Cannot write data to system activity file: No space left on device


Recommended Posts

Hello everyone.  Need some assistance here.  I have never seen this error before and I am having a hard time trying to find out how to solve it.  I keep getting email alerts.

 

Subject: cron for user root /usr/lib/sa/sa1 2 1 1> /dev/null

 

Body: Cannot write data to system activity file: No space left on device

 

 

All of my drives have some space left but obviously something is going on.  The mover script is not running and I cannot figure out what is trying to be saved where so that I can try and resolve this issue.  I have received 50 emails so far and continue to get them every minute.

 

Thanks in advance.

Enter "free -lm" when it happens and post the output.

Why is /var/log full?

 

Enter "ls -la /var/log"

A bit of a late follow on - but as of about 2:30 this morning one of my 2 servers has been mailing me every minute with the

cron for user root /usr/lib/s?a/sa1 2 1 1> /dev/null "Cannot write data to system activity file: No space left on device" mail.

There was nothing happening on either server at this time, its just kind of started, so i guess its:

 

What does this mean and why might it just start up?

Do i just look into the syslog to see which server is firing off the mails and so which one has the problem as that info is not in the header or message

 

And most improtant what do i do to fix the problem? it seems from what i have read a restart will flush everything but thats not a fix is it, its just a work around, you should be able to just leave this stuff running

 

Would check the syslog and post etc but i am at work for the next few hours and i wanted to get the issue on the table

 

Many thanks

 

Update: Restarted the servers as i have now upgraded to 5.0.4 and the cron problem has gone away - but I would still like to understand a little more about this for next time

How do I stop these Cron emails? I do not need to know that this cron job is happening every 2 hours. My mailbox is full of this.

Do you have (or have you ever had) SimpleFeatures, unMENU, or Dynamix installed?

Email notifications are NOT standard. You have to have installed a plugin, and then setup the plugin with your email addy to cause these to be generated.

I have unraid status emails setup. There was no option for any cron emails. They also started after setting up the port forward script for the openvpn plugin. I have simple features and unmenu

Would appear to be a couple of things happening:

The RAM is filling up, this is easily fixed with a reboot.

Crontab is setup with a "MAILTO:address".

 

Folks forget this latter setting is out there. Once set (by SF for example), the MAILTO is likely to be persistent even if the GUI interface changes the cron schedule.
