I've run the following df command on my system and get the following output:

Notice that the disk usage statistics are identical for each mount point. Each mount point is actually a folder that sits on a windows machine. It seems impossible that each mount point is using and consuming the same amount of space. I have checked the usage in Windows by doing a right-click and properties on the actual folders.

Can anyone explain this?

Each mount point is actually a folder that sits on a windows machine.

If those folders are all on the same filesystem, df will be reporting that same filesystem's stats for each mount because that's what windows (and I expect any network filesystem) will report.

Makes sense. Thanks! – user106563 Nov 18 '13 at 18:46
@user106563 If this answer solved your problem, please remember to mark it as accepted and/or upvote it instead of posting a thank you comment. That is the way thanks are expressed on SE sites. – terdon Nov 18 '13 at 19:05
@terdon Don't know where to put this, you're here, lucky you: I have to say I don't understand the closure. I don't see what detail he could have usefully given or left out, or how his question could be clearer. What would be the right place to say this? – jthill Nov 20 '13 at 13:45
If you disagree with the closure of this question you can either vote to reopen (needs 3k rep) or you can post a question on Unix & Linux Meta about it. A lot of the regular users also hang out in Unix & Linux Chat so you can come and ask there. I did not vote to close this so I can't speak for those who did but the question is not very clear, the df command is not shown and one has to infer what is going on (as you did). – terdon Nov 20 '13 at 13:52
