Use S3QL to mount object storage containers

Use S3QL to mount object storage containers

S3QL is a remote file system that can be configured locally to store data using cloud storage solutions like OVH Object Storage. It has several features, such as data compression, encryption, and container snapshots, which makes this solution particularly suitable for creating backups.

You can find more information directly on their website.

This guide shows you how to set up an object container as file system.


Please note

Using an object container as a file system can impact the performance of your operations. S3ql version 3.3 or above is required.

Create your file system

  • Create a file containing the login information:
admin@serveur1:~$ sudo vim s3qlcredentials.txt

backend-password: OS_PASSWORD
storage-url: swiftks://
fs-passphrase: PASSPHRASE

OS_PROJECT_ID, OS_USERNAME and OS_PASSWORD parameters can be found in your OpenRC file. You can follow this guide below in order to retrieve it:

The REGION_NAME and CT_NAME arguments can be adapted according the name and location of your object container.

  • Change authentication file access permissions:
admin@serveur1:~$ sudo chmod 600 s3qlcredentials.txt
  • Object container formating:
admin@serveur1:~$ sudo mkfs.s3ql --backend-options domain=default --authfile s3qlcredentials.txt swiftks://

You then have to add the passphrase to your authentication file. If you do not want to configure it, you have to delete the "fs-passphrase: PASSPHRASE" line from your file.

Configure your file system

  • Create the mounting point
admin@serveur1:~$ sudo mkdir /mnt/container
  • Mount the object container
admin@serveur1:~$ sudo mount.s3ql --backend-options domain=default --authfile s3qlcredentials.txt swiftks:// /mnt/container/
  • Check mounting:
admin@serveur1:~$ sudo df -h

Filesystem Size Used Avail Use% Mounted on
/dev/vda1 9.8G 927M 8.5G 10% /
udev 10M 0 10M 0% /dev
tmpfs 393M 5.2M 388M 2% /run
tmpfs 982M 0 982M 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 982M 0 982M 0% /sys/fs/cgroup
swiftks:// 1.0T 0 1.0T 0% /mnt/container

You cannot use S3QL in offline mode, you should not configure persistance via the /etc/fstab file but by using a script which will run when your sever starts up.
