I have a single node installation. Home lab. Just trying to better understand what I'm looking at in the screenshot provided. Basic installation with LVM creates root, swap, and data. I have a few questions. 1. Based on the screenshot /dev/sda3 must be "data", correct? I can manipulate sda3 and never hurt root and swap? Just don't mess with /dev/sda1, /dev/sda2, and /dev/mapper (if any of that is even possible). 2. Physical Volumes, disk partitions, LVM, and mixed classes of storage. Currently both of my hard disks are LVM2 members. I also have an external drive /dev/sdc1 (in the screenshot) that has not been mounted. If I want to use it to store any type of file that can be then shared with my virtual machines on LVM, should I (can I) use a different storage class such as NFS? Or is there a more logical alternative?
