I am building out a replacement server which will be the target for a server migration. The server will host an NSS volume. In the past I have always created an array-level logical drive for my NSS partiton/volume. Rather than doing this, I would rather just have one logical drive and partition the space using LVM (except for /boot and swap). Once I create the LVM and add /, /home, /var, /tmp to it, I will have a lot of extra space which I want to use for the NSS volume.

So, is it possible to use the unused space in LVM for NSS? Or should I stick which a separate logical partition for NSS?
