Just a quick reminder, for myself 😉

Needed to resize a partition on RockyLinux 9.5
And wanted to document that.

So this was a /home partition, on a LVM system.

Steps I took:

• Backup /home –> tar -czvf /root/home.tgz -C /home .
• Test Backup –> tar -tvf /root/home.tgz
• unmount /home –> umount /dev/mapper/rl_<NAME_OF_MACHINE>-home
• Remove logical volume –> lvremove /dev/mapper/rl_<NAME_OF_MACHINE>-home
• Recreate new /home (250GB) –> lvcreate -L 250GB -n home rl_<NAME_OF_MACHINE>
• Format –> mkfs.xfs /dev/rl_<NAME_OF_MACHINE>/home
• Mount –> mount /dev/mapper/rl_<NAME_OF_MACHINE>-home
• Extend /root –> lvextend -r -l +100%FREE /dev/mapper/rl_<NAME_OF_MACHINE>-root
• Restore backup –> tar -xzvf /root/home.tgz -C /home

Just a reminder for myself.

Can use in Cloud-init to set password for the root account.

#cloud-config
ssh_pwauth: true
users:
  - name: root
    lock_passwd: false
    hashed_passwd: HASHED_PASSWORD
    ssh_authorized_keys:
      - ssh-rsa <key>
