Deleting LVM Pools

Running ubuntu Mate 24.04 and LVM version: 2.03.16(2) (2022-05-18)

Due to my ignorance I have created multiple lvm pools over time as I have created and deleted virtual machines. At the moment I have these LVs:

Obviously /dev/vg01/root and /dev/vg01/home are crucial to my system and to a large degree so is /dev/vg01/ubserver. The other VMs are temporary for various reasons. Attached are just two of my pools - each showing the same Volumes. My question is:

a. It is worth/possible to clean up these multiple pools - so having just one pool referencing all the volumes?

b. At the moment my understanding is that these pools are just small files in /etc/libvirt/storage/ so I might as well leave it ‘as is’. Perhaps I’m wrong - is there more to a ‘pool’ than just these small xml files?

Any advice appreciated.

I’ve removed an unwanted pool in the past from the virt-manager list by using the virsh terminal command. I looked back at my logs for an entry when I did that, and the terminal command I used was:

sudo virsh pool-destroy poolname

You can then create a new pool(s) to better organize.

Some other commands that are useful:

list all vms:
sudo virsh list --all

list all pools:
sudo virsh pool-list

list pools of logical storage (lvm) type
sudo virsh pool-list logical

list pools of file type storage
sudo virsh pool-list dir

For complete list of the virsh commands (there are many) and what they do, see the man page of virsh.
