I'm completely new to lvm.
Then you really should read more about LVM and experiment it before installing a system on LVM.
lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert root build-vg -wi-ao---- 463.52g swap_1 build-vg -wi-ao---- 2.00g I used the default stretch of an lvm partition with the gnome. To me, it seems me the partition is too large to to reduce for snapshots.
What do you mean ?Did you allocate all the available space in the volume group to the logical volumes ? Creating snapshots requires space.
What would be a good layout for a stretch install doing lvm snapshots?
When installing with LVM, an important rule is to always leave plenty of free space in the volume group. Don't worry, extending a logical volume when needed is easy. This implies to use manual partitioning, because guided partitioning allocates all the available space.
