Hello everyone, I need to know if I can change a HD from lvm to lvm-thin, I have a vm on this hd that is on lvm and its backups are coming from the size of the hd and not from the use of the vm.
Yes, you can convert it.
But you have to trim the fs in the VM anyway to reduce the backup size.
Enable the discard on the vdisk and run a fstrim inside the VM then you will see that the backup size will be reduced.
