31 December 2023 - 4TB SSD Hard Drive on NUC 13 Pro Kit running Rocky Linux 9.3

• Install gparted RPM
• Start up gparted as root
• Select the /dev/sda disk using the pull-down menu in the upper right corner
  • Note that the primary disk is /dev/nvme0n1
• Device > Create Partition Table…
  • Choose the default 'gpt'
• Partition > New
  • Select defaults except for the following:
    • Partition name: disk2
    • Label: disk2
    • File system: ext4
  • Click Add
• Click green check mark to Apply All Operations
• Open an xterm as root
• mkdir /disk2
• You need to modify the /etc/fstab entry to something like the following
  • UUID=XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX /disk2 ext4 defaults 1 1
• You find the UUID for the new hard disk by going to /dev/disk/by-uuid/ and doing ls -l
• There you will see the UUID pointing to the drive (ex. ../../sda)
• Use that information to update /etc/fstab
• systemctl daemon-reload
• mount -a
• df -hP
  • Ensure you see /disk2 mount and you can cd in and touch/remove a test file
• Reboot to ensure disk mounts correctly

19 April 2016 - 3TB Hard Drive on CentOS 6

See Installing 3TB Hard Drive on Debian

• Couldn't use default partition scheme (2 TB is largest supported disk)
• Had to make a new partition using the GUI application GParted in format 'gpt'

Follow the instructions on this page. But if you are using SATA drives, replace "hdb" with "sdb" and "hdb1" with "sdb1", etc.

For newer hardware, see http://go2linux.garron.me/linux/2010/09/uuid-linux-fstab-file-766 for UUID information.

Mounting a hard drive with UUID in /etc/fstab

4 July 2015 Notes

Backup any important files

vi /etc/fstab to remove old HDD entry first Remove/replace drive. Boot.

Use rescue mode if you forgot to undo /etc/fstab RHEL6 rescue mode:

vi /etc/fstab to remove old HDD entry.

Reboot, get this prompt:

SELinux relabeling required.

Note, each * is 1000 files that have been relabeled

Relabeling took 18 minutes on a 250MB primary drive 87% full. Not sure how many files it had.

Partition the new drive:

the physical sector size. Aligning to a physical sector (or optimal
I/O) size boundary is recommended, or performance may be impacted.

Format the new drive:

• Open up Applications > System Tools > Disk Utility
  • Note for CENTOS7 you need to install gnome-disk-utility
  • Then run: gnome-disks
  • Upper right hand corner has the link to view SMART data
• See Storage Devices on left side of GUI
• Click on the new hard drive
• Should see new partition
• Click Format Volume
• Give it a label, use default (ext4)

Update /etc/fstab with drive UUID in /dev/disk/by-uuid

mount -a

Reboot as final test.
