Scale Volumes
You can expand your NVMe-SSD and Bulk volumes at any time as needed, even during live operation.
In the cloud control panel, you can scale your volumes either under "Storage > Volumes" or, if the volume is attached to a virtual server, in the server's detail view on the "Storage" tab.
You can increase the size of NVMe-SSD volumes in steps of 1 GB, and Bulk volumes in steps of 100 GB.
Please note: Volumes cannot be reduced in size. If you only need more storage space temporarily, it may be advisable to attach or scale an additional volume. Such an additional volume can be deleted later (and, if necessary, replaced with a smaller volume), while the root volume is permanently tied to the virtual server.
After expanding the volume itself, the partition and file system must also be expanded to use the additional space. For a root volume, cloud-init will typically handle this during the next reboot. Without a reboot, or in the case of an additional volume, we recommend the following procedure, where /dev/... is the device path of the volume:
# Resize partition
growpart /dev/X 1
# Resize file system
resize2fs /dev/X1
