I am trying to resize an encrypted physical volume so that I have free space to make a dual boot system.
So far, I've successfully decrypted the PV, resized the filesystem and the LVs but when I try to resize the PV I run into issues relating to the sector extents of my LVs.
root@ubuntu:/home/ubuntu# pvresize --setphysicalvolumesize 174G /dev/mapper/cryptdisk
/dev/mapper/cryptdisk: cannot resize to 44543 extents as later ones are allocated.
0 physical volume(s) resized / 1 physical volume(s) not resized
On the physical volume I have two logical volumes: root (first) and swap (second). I've resized (shrunk) the root volume to create free space, but the extents of the free space lay between the root and swap volumes. Because the extents of the swap volume are located at the end of the physical volume, I cannot shrink the physical volume using pvresize.
How can I change the extents of the swap volume so that the free space is located after it?
I've had a look at pvmove, but I don't think it's what I need - in this case I need something like lvmove (but it doesn't exist).
