[linux-lvm] lvcreate distributed extent option

[ZECHA,HOLGER (HP-Germany,ex1)]

Hello,

there still seems to be a missunderstanding
I want to have the following:

   --- Logical extents ---
   LE    PV                        PE     reads      writes
   00000 /dev/sdd1                 00001  0          1        
   00001 /dev/sde1                 00001  0          0        
   00002 /dev/sdf1                 00001  0          0        
   00003 /dev/sdg1                 00001  0          0        
   00004 /dev/sdh1                 00001  0          0        
   00005 /dev/sdi1                 00001  0          0        
   00006 /dev/sdd1                 00002  0          0        
   00007 /dev/sde1                 00002  0          0        
   00008 /dev/sdf1                 00002  0          0        
   00009 /dev/sdg1                 00002  0          0        
   00010 /dev/sdh1                 00002  0          0        
   00011 /dev/sdi1                 00002  0          0        
   00012 /dev/sdd1                 00003  0          0        
   00013 /dev/sde1                 00003  0          0        
   00014 /dev/sdf1                 00003  0          0        
.....

but with  lvcreate -I 8 -L 40000M -n lvdata /dev/vgtest /dev/sdd1 /dev/sde1
.... I get

   --- Logical extents ---
   LE    PV                        PE     reads      writes
   00000 /dev/sdd1                 00063  0          1

   00014 /dev/sdd1                 00077  0          0  
...

   02106 /dev/sde1                 00064  0          0

   02109 /dev/sde1                 00067  0          0        
   02110 /dev/sde1                 00068  0          0        
   02111 /dev/sde1                 00069  0          0        
   02112 /dev/sde1                 00070  0          0        

A distribution like described above looks like this on HP-UX LVM:    

   00000 /dev/dsk/c16t0d0   00012 current
   00001 /dev/dsk/c16t0d1   00012 current
   00002 /dev/dsk/c17t0d2   00000 current
   00003 /dev/dsk/c17t0d3   00000 current
   00004 /dev/dsk/c16t0d4   00000 current
   00005 /dev/dsk/c16t0d5   00000 current
   00006 /dev/dsk/c17t0d6   00000 current
   00007 /dev/dsk/c17t0d7   00000 current
   00008 /dev/dsk/c16t1d0   00000 current
   00009 /dev/dsk/c16t1d1   00000 current
   00010 /dev/dsk/c17t1d2   00000 current
   00011 /dev/dsk/c17t1d3   00000 current
   00012 /dev/dsk/c16t1d4   00000 current
