Device label being shown none on Ubuntu server 10.04

[Kaushal Shriyan]

Hi,

I have not understood about the device label being none on Ubuntu
Server 10.04 and on Ubuntu Server 8.04 it appears to be correct.
Please help me understand about it.

On a 8.04 Ubuntu Server

Filesystem    Type    Size  Used Avail Use% Mounted on
/dev/sda1      xfs    461G  118G  343G  26% /

On a 10.04 Ubuntu Server

Filesystem    Type    Size  Used Avail Use% Mounted on
/dev/sda1      xfs    522G  645M  521G   1% /

/dev/sda3     ext3    490M   27M  438M   6% /boot

Also I see the (none       debugfs    522G  645M  521G   1%
/var/lib/ureadahead/debugfs) and (/dev/sda1      xfs    522G  645M
521G   1% /) the same on Ubuntu server 10.04, Any clue ?

Thanks and Regards
