Nicholas: 1. My RAID array is partially filled and backed up. 2. I prefer to mount by UUID. 3. n/a 4. the relevant content of my blkid is: "/dev/sda1: UUID="AEF6-E013" TYPE="vfat" PARTUUID="b4b9c894-aa4f-4c83-ba27-8919eaaeac49" /dev/sda2: UUID="a428a1ea-5174-47b6-a894-521166a7a354" TYPE="ext2" PARTUUID="e25bcabb-2fd3-4515-bf74-3a2f0c548fec" /dev/sda3: UUID="1b413c7c-d39d-4c10-9f1d-4f3a21791c50" UUID_SUB="e2d12168-c216-425f-9a82-6d46dad8ccc8" TYPE="btrfs" PARTLABEL="primary" PARTUUID="1651d9f1-35ff-458b-ae64-bb6003c72159" /dev/sdb: UUID="c2cf44d3-28e0-492a-9d51-00a41b71428d" UUID_SUB="b4c6bbc5-ea80-4a79-89ca-333d351b09e5" TYPE="btrfs" /dev/sdc: UUID="c2cf44d3-28e0-492a-9d51-00a41b71428d" UUID_SUB="c4ac65e7-45bb-4450-9aa4-80a7fbebed3a" TYPE="btrfs" /dev/sdd: UUID="c2cf44d3-28e0-492a-9d51-00a41b71428d" UUID_SUB="5f55bf3b-8e82-4b50-8b62-5dc45c892281" TYPE="btrfs" /dev/sde: UUID="c2cf44d3-28e0-492a-9d51-00a41b71428d" UUID_SUB="5a12cbd5-bdc2-4258-9bc8-23d95cbb1db6" TYPE="btrfs" I omitted /dev/sdf from my blkid content as it is an unused, transitory drive that will be redeployed after "/" is moved to the array. /dev/sda is my flash drive with separate partitions for efi (vfat), /boot/ (ext2) and "/" (btrfs subvolume).
