I am trying to use LVM on my Red-Hat Linux 8.0.
I haved created volume group using 3 partitions on my machine
(/dev/hda7,/dev/hda8,/dev/hda9).All the partions are of same size 200 MB.Then
I have created stripped logical volume on 3 partitions using following command.
#lvcreate -i3 -I4 -l24 -nmy_stripped_lv1 my_volume_group
I have also tried extending logical volume and shrinking logical volume. All this worked fine for me.
Now I tried pvmove command.
#pvmove /dev/hda9
But it will be giving following error message
***********************
pvmove /dev/hda9
pvmove -- moving physical extents in active volume group "my_volume_group"
pvmove -- WARNING: if you lose power during the move you may need
to restore your LVM metadata from backup!
pvmove -- do you want to continue? [y/n] y
pvmove -- not enough free/allocatable physical extents**************************
When I get above error message the output of vgdisplay is as follows
*************
--- Volume group ---
VG Name my_volume_group
VG Access read/write
VG Status available/resizable
VG # 0
MAX LV 256
Cur LV 1

When I get above error message the output of lvdisplay is as follows
******************

When I get above error message the output of pvdisplay for /dev/hda7,/dev/hda8, /dev/hda9 is as follows (same for all)
************************

**********************
So please guide me what should I need to do so that I will be able to get pvmove working
Thanks and Regards Kiran
