Re: free space reports

[Yaroslav Halchenko]

I'm still confused because there is such a wide difference between what
is reported with cfengine and what is reported by df

I've defined a class when cfengine mentiones low-space condition, and
just run df at that time point:


cfengine:ravana: Free disk space is under 20% for partition
cfengine:ravana: containing /var (18% free)
cfengine:ravana: Executing script /bin/df /var...(timeout=0,uid=-1,gid=-1)
cfengine:ravana:/bin/df /var: Filesystem           1K-blocks      Used 
Available Use% Mounted on
cfengine:ravana:/bin/df /var: /dev/sda7              1542156   1251300    
290856  82% /var
cfengine:ravana: Finished script /bin/df /var

Why that could happen?
