You can add up to eight discs to your Cloud Server and 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)
Please note: You can’t decrease the size of a disc once it has been created. If you are not sure how much storage you require, better to choose too little than too much!
Add a new disc (for Linux)
- Before adding a new disc, shut down your Cloud Server.
- Click the blue
Add discbutton, choose the size and type of disc you want, and click the green
Add new discbutton. Note that changing the label of a disc doesn’t affect how your operating system will see it.
- 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/vdcetc. Run this command if you are not sure what discs are attached:
ls -1 /dev/[sv]d[a-z]
- 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
- Now you can mount the disc somewhere suitable. For example, you might want to mount
sudo mkdir /mnt/extra-storage sudo mount /dev/vdb /mnt/extra-storage
- To make sure it gets mounted at every boot, add this line to
/dev/vdb /mnt/extra-storage ext4 defaults 0 0
This step is optional and applies only to Symbiois users.
Symbiosis makes daily backups to
/var/backups. It is more robust to put these backups on an archive disc (it uses cheaper storage too). 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 check 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
Add a new disc (for Windows)
- Find your Cloud Server and click on the
Add discbutton. Note that if you change the label of a disc, it doesn’t affect how your operating system will see the disc.
- Open Windows Disk Management.
- Partition your disc as required.
