Hii All,
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
*************
