psutil.disk_usage returning same values for all partitions

[vitorluis]

Hi all,

i'm writing a application, that read some hardware data, and one of them is the partitions data.

So, when i execute the psutil.disk_partitions i get all the partitions, and that's OK.

But when i execute the psutil.disk_usage('mount_point'), all partitions return the same free, used and total values.

Follow, two screenshots to show this situation:

And

Both partitions are XFS filesystem, but my '/' partition are EXT4 and also return this values. And i don't if is a problem, i running the psutil function in a new Thread.

To complement, i'm using Ubuntu 15.04.

I'm not sure I understand. Are you complaining that 2 different paths return the same values?
That is expected behavior in case the 2 paths belong to the same mountpoint.
For example on my Linux box / and /tmp return the same values because /tmp is mounted under /.

Yes, 2 different paths are returning the same values.

But, as you can see on the screenshot, the mount point /home is pointing to /dev/sda3. And the other mount point /usr is pointing to /dev/sda6.

So, does not have 2 mount points, pointing to the same partition.

Oh man, i'm realized that i passing the device path, not the mounting point. So sorry about that :(
