[linux-lvm] Re: HELP changing md-device's partition-type to LVM(or may be LV's partition id)

[svetljo]

i have forgoten my mail : svetljo at lycos.com 
 galia at st-peter.stw.uni-erlangen.de
i'll be tankfull for any idea  write me

and one more question :

can i make a VG and LV's over  LV's
the idea is replacing the linear sofware RAID with a linear LV's, but i 
think i'll have the same roblems that i had with the raid

the LV ( lvcreate -i3 -I4 -L26G -nMusic )

the VG -> myData   /dev/hdh10 /dev/linVG1/linLV1 /dev/linVG2/linLV2

/dev/hdh10 normal partition 14G
/dev/linVG1/linLV1 ->  linear LV 14G /dev/hde6 /dev/hde12
/dev/linVg2/linLV2 ->  linear LV 14G /dev/hdg1 /dev/hdg5 /dev/hdg6 
/dev/hdg12
