XFS & Veeam Repository

Today I’m going to talk about how to create a new Veeam repository using XFS file system.

As many of you already know, v. 10 of Backup & Replication loves Linux. There are 3 top features that attest it and they are:

  • Xfs integration
  • Proxy Linux
  • Direct NFS Repository

The first article wants to talk about the XFS Integration and  which steps you should follow to use this smart technology integrated with Veeam Repositories

We will have 3 majors steps:

  1. Adding New Disk and formatting it as XFS
  2. Adding a Backup Repository
  3. Working and testing with XFS integration

So, let’s start with Point 1, remembering how to add a new disk to a Linux Server (we consider you have already added a disk to your physical or virtual Server)

First command is lsblk  that shows which disks have been recognize by the Operating System (in my case the new disk has been seen as sdc)

sda           8:0    0   16G  0 disk

├─sda1        8:1    0  600M  0 part /boot/efi

├─sda2        8:2    0    1G  0 part /boot

└─sda3        8:3    0 14.4G  0 part

  ├─cl-root 253:0    0 12.8G  0 lvm  /

  └─cl-swap 253:1    0  1.6G  0 lvm  [SWAP]

sdb           8:16   0  200G  0 disk

└─sdb1        8:17   0  200G  0 part /media/RepoXFS1

sdc           8:32   0   16G  0 disk

sr0          11:0    1    7G  0 rom

Now you have to run fdisk -l  /dev/sdc to understand the size of the disk.

Disk /dev/sdc: 16 GiB, 17179869184 bytes, 33554432 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
fdisk /dev/sdc to create new partition

Now create a new disk (this procedure delete any previous file system present) with the command fdisk /dev/sdc.

Just follow the steps below to create the new disk  

    1. n to create a new partition
    2. p to create a primary partition
    3. 1 (default)
    4. First sector (default)
    5. Last sector (default) (if you want to use all the disk capacity)
    6. w write 

Just relaunch the  lsblk command and watch if  sdc1 correctly appears.

lsblk /dev/sdc

NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sdc 8:32 0 16G 0 disk
└─sdc1 8:33 0 16G 0 part /media/RepoXFS2

Two more steps for first phase 

Creating File system XFS with Data-Block Sharing enable (reflink=1) with the following command:

make.xfs -m reflink=1,crc=1 /dev/sdc1  (default block is 4096)

Create the mount point on your server with the command cmkdir /mountpoint/xfs-1

Mount file system addicting the following line in /etc/fstab file

/dev/sdc1 /mountpoint/xfs-1         xfs     defaults        1 2

Reboot the server and everything should work.

See you soon with second phase.
