[Alan Pek <alan pek db com>]

Hi Folks,

How do I properly backup and restore
/ on LVM2 , e.g.

Filesystem    
      1K-blocks      Used Available Use%
Mounted on
/dev/mapper/rootvg-rootlv
       
               2621356   1902288
   719068  73% /
tmpfs      
          25165824        
4  25165820   1% /dev/shm
/dev/cciss/c0d0p1  
    106040     45992     60048  44%

Am running SLES9 , should be similar
in Redhat and my pvdisplay looks like, HW RAID 1.
