lvm
 

i configured lvm properly. and its working. problem arises when i added a new volume.

fdisk /dev/hdd
:n
:l
+10000M
:t
:8e
:w
# reboot
#init 1
#pvcreate /dev/hdd1
#vgextend lvm_group /dev/hdd1
#lvexten -L+5G -v /dev/lvm_group/lvm0 /dev/hdd1
#vgdisplay

it properly show me with new size (free and allocated PE) but LV(logical volume ) not extended in size , it show me old size, it i format the volume then it show me correct size,

Any one know how to solve please help. thanks in advance

As far as I know, you always have to format the new volume for the correct size to show up.

this mean new things are possible but not working properly.
if you have 1TB data and disk is full and you have to add a new volume. then format it ?
in this case windows is best whats your opinion. low administration and proper workout. full support and documentation. this really hurt me.
