XFS – Resize the immutable file system

In the Veeam Backup & Replication environment, it may be necessary to expand the allocated space of a Linux repository.

In my environment, there is an Ubuntu 22.04 server to which a second disk(dev/sdb) was added, formatted as xfs, and made available as mount point /mnt/backup/ .

The server is used in hardened repository mode (immutability)
(https://helpcenter.veeam.com/docs/backup/vsphere/hardened_repository.html?ver=120).

Let’s look at the simple procedure:

  • The packages to install are cloud-guest-utils and gdisk:
    “sudo apt -y install cloud-guest-utils gdisk”
  • To find out the structure of the file system use the command:
    “sudo lsblk”

      • The result shows the sizing, and mount point of Ubuntu server file system:
        NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
        sda 8:0 0 16G 0 disk
        ├─sda1 8:1 0 1M 0 part
        ├─sda2 8:2 0 1.8G 0 part /boot
        └─sda3 8:3 0 14.2G 0 part
         └─ubuntu–vg-ubuntu–lv 253:0 0 10G 0 lvm /
        sdb 8:16 0 100G 0 disk. └─sdb1 8:17 0 80G 0 part /mnt/backup
        sr0 11:0 1 1024M 0 rom
  • To find out if the file system has additional space to allocate:
    “sudo growpart /dev/sdb 1”

    • The result shows the item changed
      CHANGED: partition=1 start=2048 old: size=167770079 end=167772126 new: size=209713119 end=209715166
  • The final command that widens the file system is: sudo “xfs_growfs /mnt/backup/”
  • Check the result through the command already seen: “sudo lsblk”
