I installed some old hard drives into my server to get some files off them. They
were a RAID 1 array, using LVM and encrypted with LUKS. It was confusing to
figure out which /dev entries belonged to what, and in what order
RAID/LVM/LUKS was setup. After some searching I found the lsblk command which
gives a nice visual layout of how the devices are laid out:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 10.9T 0 disk
└─md0 9:0 0 10.9T 0 raid1
└─dm_crypt-0 253:0 0 10.9T 0 crypt
└─vg0-home 253:1 0 10.9T 0 lvm
