unable to find volume name in Reiser file partition

I have installed LInux /suse in two hard discs,both have the same number of partitions,two partitions
named '/boot' & '/' have ex2 file format,while the remaning /usr has Reiser file format.
 all the partitions have same capacity.but when i analyze both the hard discs in winhex,i found volume name "/usr" at '/' partition as well as '/usr' partition also in one hard disc,and in another one it founds only at '/' partition.
what would be reason behind this?

A volume name is not in the file system but in the superblock of the filesystem.
(or more exactly it is named a 'label')

When your system is operational try the 'df' or 'mount' commands it'l show you what is mounted where.

In the real root volume (/) I would expect to find an empty directory name /usr, what the mount command does is attach filesystem on the device /dev/whatever/partition  to the /usr directory.
When anything below the /usr directory is accessed, it will actualy go to the /dev/whatever/partition
based filesystem.

The mapping of mount is done through individual mount commands or through 'mount -a' using the /etc/fstab file to mount the various file systems. These filesystems can be based on the device names or the labels in their superblocks.

Forced accept.
