Re: File system overhead

 If you look at the output of df -h you will see that the size of the

added to it, nothing has ever been removed.

By my calculations there should be 218.8GB left, so if not the rest must be filesystem overhead. 5 percent seems to be a bit much, but as long as I can explain it I may be able to live with this. That is why I want a link to a
site that could explain the overhead of the ext3 filesystem.

did you execute the df command as root? if not, it might report less free space. there is a reserved space (5% is default for ext2/3, iirc, however you can set it up differently) that is available only for root... and since you report 5% in your case...

able to help support her machine. I run Fedora Core 2.)

I have *less* available as root than as ordinary user...

But certainly not anything like 5%. And my numbers also
don't quite add up.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
