Manage a server’s storage

The Storage tab shows the disks of one server. The boot volume holds the operating system. Data volumes are extra disks you add for files and databases. A volume is billed by the GB-hour from the moment it is created, attached or not.

Read the tab

1. Open the server’s page, then the Storage tab.
2. Volumes lists each disk with Volume, Size, Device, Status, Attached and Deleted With Server. Boot Volume marks the disk the server starts from. Device is the disk’s name inside the server, for example /dev/vdb.
3. The line under the title counts the volumes on this server and how many of the project’s allowed volumes are used.

Add a new volume

1. Select Create New Volume.
2. Type a Name and a Size (GB).
3. Confirm. A new blank volume is created in the server’s zone and attached to it.
4. Inside the server, format and mount the new disk.

Attach an existing volume

1. Select Attach Existing Volume, or open Available Volumes.
2. Under Choose a Volume, pick a volume.
3. Confirm. Mount it from inside the server afterwards.

Extend a volume

1. Select Extend on the volume’s row.
2. Set the new size with the slider or the box. Volumes can grow, never shrink. The Estimate: line shows the extra monthly cost.
3. Confirm. You see Volume Extend Requested.

For the boot volume, the server keeps running and its root filesystem grows at the next reboot. Reboot Now restarts it straight away. For a data volume, grow its filesystem inside the server with the commands shown, or use Grow Filesystem.

Grow a data volume’s filesystem

Grow Filesystem makes the filesystem fill the whole volume after you extend it.

1. Select Grow Filesystem on the volume’s row.
2. Choose the Filesystem already on it: ext4 or XFS. Run lsblk -f inside the server if you’re not sure.
3. Confirm. The server goes offline for about a minute while it restarts into maintenance mode. Nothing on the volume is erased.

You see Filesystem Grown, or Nothing to Grow when it already filled the volume. LVM, btrfs and encrypted volumes can’t be grown here.

Detach a volume

1. Inside the server, unmount the disk and remove it from /etc/fstab.
2. Select Detach on its row and confirm. The volume and its data are kept, unattached.

Delete a volume

1. Select Delete Volume on its row.
2. Optional: tick Take a Backup First to make a full backup now.
3. Type the volume’s name to confirm.

The data on it can’t be recovered unless it has a backup. Its existing backups are kept.

If something goes wrong

• This project already has its maximum number of volumes. Delete one, or contact support for more. To ask for more, open a support ticket.
• Volume Created but Not Attached means the volume exists under Available Volumes. Attach it again, or delete it.
• Filesystem Not Grown shows the reason. The data wasn’t touched.
