Partition, filesystem, mount

Articles

• lsblk — block devices — A tree of disks, partitions, and logical volumes — size, filesystem, mountpoint.
• fdisk and parted — partition a disk — fdisk and parted write a partition table (GPT or MBR) and partitions to a disk; parted -s runs without prompts.
• mkfs — create a filesystem — The mkfs command creates an empty ext4 or xfs filesystem on a partition; the old data on it becomes unreachable.
• blkid — filesystem UUID, label and type — The blkid command prints the UUID, label and type of the filesystem on a device — what goes into /etc/fstab.
• Mounting and fstab — Mounting filesystems: the mount command, persistent mounts in /etc/fstab, UUIDs and options.
• Loop device — a file as a disk — A Linux block device using a regular file as its backing storage.
• Filesystems: ext4, xfs, fsck — Filesystems: creating one with mkfs, labels and UUIDs, fsck checks, choosing between ext4 and xfs.
