We are going to move LVM partition from /dev/sdb1 to /dev/sda3. Boot into SystemRescueCD Switch to root. su - root New partition Create an new partition on new disk using one of this tools (sfdisk, fdisk, gparted). If you choose to use gparted, you need to VNC into the server using ip_address:5901. Create a physical volume pvcreate /dev/sda3 Add the physical volume to volume group Find out the volume group name. lvdisplay In this case, vg is the logical volume group name. Add /dev/sda3/ to volume group. vgextend vg /dev/sda3 Move the data Move from old logical volume to new logical volume. Note that this will take hours to finish depending on the size of the volume. Use the pvmove command to move the data f rom dev/sdb1 to /dev/sda3. pvmove /dev/sdb1 /dev/sda3 If you cannot move the data due to insufficient size, then you need to resize the logical volume group and partition. Remove the old physical volume from the volume group After you have moved the data off /dev/sdb, you can remove it from the volume group. vgreduce vg /dev/sdb1 You can now reallocate the disk to another volume group or remove the disk from the system.
