Step‑by‑Step Guide to Mount a New Disk on Linux

1. Check existing disk partitions

Use fdisk -l or lsblk to list current disks. In the example, /dev/sdb shows no partitions.

2. Create a new partition on the disk

Run fdisk /dev/sdb and follow the interactive prompts to create a primary partition (e.g., /dev/sdb1).

3. Format the new partition

Format the partition with the XFS filesystem using:

mkfs.xfs /dev/sdb1

4. Verify the filesystem type

Run blkid to list all block devices and their filesystem types, confirming the new XFS partition.

5. Mount the partition temporarily

Mount it to a chosen directory (e.g., /ynat/) with:

mount /dev/sdb1 /ynat/

Note: This mount is temporary and will disappear after a reboot.

6. Configure automatic mounting at boot

First obtain the partition UUID with blkid. Then edit /etc/fstab (using vi or another editor) and add a line similar to:

UUID=your‑partition‑uuid   /ynat   xfs   defaults   0   0

Make sure each field is separated by spaces.

7. Reboot and verify

Reboot the system with reboot. After the system starts, run df -h to confirm that the partition is mounted at the target directory.

If the mount is missing, revisit step 6 to ensure the /etc/fstab entry is correct.
