Online RootFS growth
On growth-enabled images, Sandbox0 automatically expands the writable RootFS as free space runs low, within a configured sparse logical ceiling up to 64 TiB. Agent processes keep running. Growth is enabled in the qualified Cloud region; confirm activation for other regions. Existing images and snapshots retain their captured storage geometry. The ceiling is logical capacity, not preallocated host disk.
The current Cloud GPU FAQ excludes instance upgrades and GPU-device changes. That differs from Sandbox0 automatically enlarging an enabled complete writable RootFS; separately attached storage and other Vultr product families have their own policies.
