- S3QL mounting container
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.
Using an object container as a file system can impact the performance of your operations.
Create your file system
- Install S3QL:
admin@serveur1:~$ sudo apt-get install s3ql
The latest version should be available in the Debian 8 repository
- Create a file containing the login information:
admin@serveur1:~$ sudo vim s3qlcredentials.txt [swift] backend-login: TENANT_NAME:USERNAME backend-password: PASSWORD storage-url: swiftks://auth.cloud.ovh.net/REGION_NAME:CT_NAME fs-passphrase: PASSPHRASE
Information such as TENANT_NAME, USERNAME 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 --authfile s3qlcredentials.txt swiftks://auth.cloud.ovh.net/GRA1:CT_S3QL
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 --authfile s3qlcredentials.txt swiftks://auth.cloud.ovh.net/GRA1:CT_S3QL /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://auth.cloud.ovh.net/GRA1:CT_S3QL 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.
