Attaching drives

You can attach up to eight discs in total using our control panel.

You can choose from two grades of storage:

  • SATA: Fast solid-state storage (based on SATA SSD drives in a RAID5 or RAID6)
  • Archive: Slower, bulk storage ideal for backups or large file serving tasks (based on SATA hard drives in a RAID6)

Each storage grade is priced differently.

Attach a new disc (for Linux)

  1. Before adding a new disc, shut down your Cloud Server.

  2. Click the blue Add disc button, choose the size and type of disc you want, and click the green Add new disc button. Note that changing the label of a disc doesn’t affect how your operating system will see it.

  3. Start your Cloud Server. Your operating system should now detect a new empty disc. The first disc in your server is usually labelled /dev/vda, with subsequent discs labelled /dev/vdb, /dev/vdc etc. Run this command if you are not sure what discs are attached:

    ls -1 /dev/[sv]d[a-z]
    
  4. Once you have determined the name of the new disc, create a filesystem. NB: Make sure you specify the correct disc, as this command will DESTROY ANY EXISTING DATA!

    sudo mkfs.ext4 /dev/vdb
    
  5. Now you can mount the disc somewhere suitable. For example, you might want to mount /dev/vdb at the /mnt/extra-storage directory:

    sudo mkdir /mnt/extra-storage
    sudo mount /dev/vdb /mnt/extra-storage
    
  6. To make sure it gets mounted at every boot, add this line to /etc/fstab:

    /dev/vdb /mnt/extra-storage ext4 defaults 0 0
    
  7. [Optional, and for Symbiois users only] Using the disc for Symbiosis backups:

    Our Symbiosis operating system makes daily backups in /var/backups. This is more robust (and uses cheaper storage) if you put those backups onto the archive disc: that storage is bound to be on different hardware, so the backups will survive even a catastrophic hardware failure.

    sudo mv /var/backups /mnt/extra-storage; sudo ln -s /mnt/extra-storage/backups /var/backups
    

    You can heck that all is well with this command:

    df -h /var/backups
    

    You should see output something like this, but the numbers will vary:

    /dev/vdb         50G   53M   47G   1% /mnt/extra-storage
    

Attach a new disc (for Windows)

  1. Find your Cloud Server and click on the Add disc button. Note that if you change the label of a disc, it doesn’t affect how your operating system will see the disc.

  2. Open Windows Disk Management.

  3. Partition your disc as required.
