Hi                                                                              
                                                               
                                                                                
                                                               
I am in the process of rebuilding my server and I am planning my disk usage.  I 
                                                               
have 2 drives.  Traditionally  I would do                                       
                                                               
                                                                                
                                                               
4 partitions to make up 4 md's                                                  
                                                               
                                                                                
                                                               
                                                                                
                                                               
md0 /boot ( ~ 500M - I like have space here) sda1 + sdb1                        
                                                               
md1 / (~10G) sda2 + sdb2                                                        
                                                               
md2 swap sda3 + sdb3                                                            
                                                               
md3 LVM PV sda4 + sdb4                                                          
                                                               
                                                                                
                                                               
from the PV I make a VG and then lots of LV's                                   
                                                               
                                                                                
                                                               
I have used this sort of set for a while, but what I would like to do is not    
                                                               
make md3 and instead use sda4 + sdb4 as 2 PV and then I get the chance to       
                                                               
decide which pv is made up of mirrored space and which is not.                  
                                                               
                                                                                
                                                               
I have some data that I don't really care if it dies/get lost.  I can't do that 
                                                               
on a lv by lv basis with my original setup.                                     
                                                               
                                                                                
                                                               
I haven't had much experience with lvm mirrors, should I stick with my original 
                                                               
setup or go with the new ?
