Discrepencies between du and df.
Hi All,
I am having a strange problem where the output of du and df do not
correlate. Here are the symptoms :
$df /var
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/hda10 606405 596139 0 100% /var
$du -s /var
54157 /var
Here we can see that du thinks there is only about 54M used but df reckons
there is over 596M used.
I am using kernel 2.2.14, which is old but I cannot upgrade because I am
using an IDE raid device from Raidzone (Smartcan) which they no longer
support and have no more drivers for. I will include further diagnostic
info below.
Here is the output of mount :
/dev/hda8 on / type ext2 (rw,errors=remount-ro)
proc on /proc type proc (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/hda1 on /boot type ext2 (rw)
/dev/hda5 on /usr type ext2 (rw)
/dev/hda10 on /var type ext2 (rw)
/dev/hda6 on /home type ext2 (rw)
/dev/rza1 on /raid type ext2 (rw)
I have attached the output of dmesg. If anyone has any advice I would be
most grateful.
Kind regards, Fred.
