I'm completely new to lvm.
Then you really should read more about LVM and experiment it before
installing a system on LVM.
LV VG Attr LSize Pool Origin Data% Meta% Move Log
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.
