Disclaimer: this is my first time using lvm.
Upon RTFM, it appears that LVM snapshots are automatically stored in the same directory as the original logical volume. In my case, that would mean the
/dev directory. This isn't very nice, because there's not enough disk space in there for me to store a large snapshot.
So when I run a command like
lvcreate --size 1G --snapshot --name snapshot /dev/lvmData/usr, I need an additional 1G of space free in /dev?
Is there any way to specify a different directory in which to store my snapshot?
