Hi,

Currently my /home partition is on the same hda as my / partition. Problem is that the / partition is getting full so i want to move my /home partition to another hda (for example the /usr hda). Is this possible without doing a reinstall?

Yes, you do not need to reinstall. I have never done this, but I think what you need to do is

Mount your new disk as /mnt/new

as root, and probably in single-user mode, you need to copy the whole contents of /home to /mnt/new, preserving ownership and timestamps of the files. I think the command would be

cp -pr /home /mnt/new

Then, in single-user mode, you need to rename /home as /home.old (in case you/I have made a mistake).

Then unmount the new disk from /mnt and then mount it as /home.

Restart multi-user mode. If everything is OK, you need to edit fstab to mount the new disk as /home at boot time.

Someone will probably make corrections for me here!

Good luck!

A better copy command is cp -dpR. This way, if he has any UNIX sockets or special files like device nodes or named pipes in his /home directory, cp won't try to read them and will just copy the files themselves.

But other than that, your method is sound.
