[SOLVED] 'tmpfs' Size and Question

Dustin Cook · 03-05-2015, 03:13 AM

Hi all,

I have a system which maps "/var/log" as a "tmpfs" filesystem with a defined size of 32MB.

What will happen to my system if this becomes full? I have a system that is over-logging and writing too much to my "/var/log/messages" file.

For reference, my RAM on the machine is 2GB.

Would this cause the device to power cycle itself?

The device won't power cycle. The syslogd or equivalent would be unable to write in them.

You can resize the tmpfs. For info see man page of mount and look in tmpfs section.

Code:

mount -t tmpfs -o remount,size=100M tmpfs /var/log

Adapt this to your system if you want.

Thanks everyone, you've given me quite a bit to think over now.
