df and dh reporting different disk space usage
I've got a problem with disk space being reported differently by du and df.
df is showing the root filesystem to be 98% full. It was reporting 100%
a few days ago but everything remained running.
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/md0 365492 336502 10120 98% /
However, du -x reports a different figure, 82Mb, which is what I would
expect:
12 /lost+found
2420 /bin
10605 /boot
82 /dev
2455 /etc
57628 /lib
1 /opt
8040 /root
2355 /sbin
1 /tmp
4 /mnt
83604 /
The machine is running woody, kernel 2.4.18. The root partition is
ext2. It has two identical disks, all partitions are raid 1 across the
two disks. It boots off a custom made CD.
I've got /usr, /home and /var mounted on different partitions. One
thought I had was I'm mounting these directories over the top of
something else, ie that there are files in the /home directory on root
before I mount, and these are now inaccessible. Is there any way to
find this out without unmounting? The machine is a production server
and also co-hosted so I'd like to avoid having to take it down.
thanks for your help,
Erik
