Hi,

I added a new user and gave him an encrypted home dir on a separate, free partition. Now there is a huge .img file there (in the size I gave to the encrypted home dir) that is almost as big as the whole partition, but if I look at the partition's properties (or kdiskfree), it says, only 4% of that partition is used...

Because of this I suspect that the .img file physically isn't stored on the partition I wanted it to be?

How can I find out, where that .img file really is stored physically?

If I look in Konqueror it shows me the following tree:

- myPartition (9.7 GB) - newuser-dir - newuser.img (9.5 GB) - newuser.key

thanks and regards

Daniel

Daniel,

I'd guess that your .img file is sparse. ie. only portions of the file that actually contain data are allocated.

Greg

Hi Greg, I still don't understand... I tried to copy this .img file to the same partition, and it copied until I stoped it (after 4 GB). Then with this partly copied file the properties of the partition showed a 50% used space. If the original .img would have been on that partition then there shouldn't be space for a second copy of it, I think. So, if there is somebody here who can tell me how I can set up an encrypted home directory within this separate partition, it would make me happy... regards Daniel -- Daniel Bauer photographer Basel Switzerland professional photography: http://www.daniel-bauer.com erotic art photos: http://www.bauer-nudes.com/en/linux.html Madagascar special: http://www.fotograf-basel.ch/madagascar/ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I suggest you try to understand what a sparse file is and why a 4GB sparse file is only occupying a small fraction of that space.

http://en.wikipedia.org/wiki/Sparse_file has some info.

Googling "sparse file" will give you lots more reading.

Thanks Greg, you're right... Instead of googling for what you said, I was checking the online translation for "sparse", which wasn't really enlightning... :-) My next question comes in a new thread...

To further illustrate the fact that the logical size of a file (that reported by ls, e.g.) need not equal the amount of disk space required to store it, repeat your copying experiment but give the the cp option "--sparse=always" and you'll find that the file can be copied despite the apparent fact that it seems to require most of the partition's available space.
