I have an Ubuntu machine with some additional attached storage. I mount the storage and create a directory in it as follows:

sudo mkfs.ext4 /dev/xvdf
sudo mount -t ext4 /dev/xvdf /home/ubuntu/tempDir
cd /home/ubuntu/
sudo chmod a+w tempDir
sudo chmod a+x tempDir

I want to move and rename the directory, e.g.

mv /home/ubuntu/tempDir /some/other/location/newName

That is, the directory will now be called newName. Do I have to re-mount in order to make sure the new dir is still attached to the extra storage?

Yes, you have to remount for it to work. Also, you may have problems if you change the directory name while the file system is still mounted.

I would suggest your unmount, rename, and then remount.

Additionally, if the mounts are in fstab you should use: Edit /etc/fstab unmount and mount again.
