Big differences between du and df

[clinty]

Hi.

A 'df -h' returns:

/dev/twed0s1e     48G    1.1G     43G     3%    /var/log

However, when I use 'du -sh /var/log' I have:

13M    /var/log

The true is 13M. So, I do not understand why df returns this value.

This is my /etc/fstab:

/dev/twed0s1f   /var/log        ufs     rw,noexec,nosuid        2       2

Anybody have an idea of this problem? It's a production server, so, I can't reboot it or unmount partitions.


Thanks !

Thanks! That's intersting.
I didn't activate Soft Updates for my fs. Do you advice me to activate it?

It's turned on, by default during install, for /usr, /var and /tmp.
