Yes, right, I meant MB of course.
Here's what I'm seeing:
root@plug001:/# df -h /
Filesystem Size Used Avail Use% Mounted on
rootfs 507M 502M 5.2M 99% /
root@plug001:/# for i in *; do du -sk $i; done 2>/dev/null
Now, /mnt is where the external USB-HDD is mounted, so discounting that I count 327 MB. Now my problem is, there's no accounting for the missing 175 MB.
Also, while I understand your point about the filesystem using compression, isn't that sort of thing meant to be transparent at the user level? Besides, I'm not able to store any more data:
root@plug001:/# touch abc
touch: cannot touch `abc': No space left on device
So I'm most definitely out of disk space... but where did it all go?
