Disk Expansion and Conversion For CloudVision VM
Cloud Vision VMs virtual disks are shipped in qcow2 format and the data disk size is 1TB by default. For better scale and performance, it is recommended that the virtual disks be converted to raw format and data disk expanded to a size more appropriate to the expected scale. At max scale supported today, we recommend a 4.5TB /data disk.
The tool can be run as /cva/scripts/cvaDiskUtil.py. It supports three commands:
/cva/scripts/cvaDiskUtil.py makeraw [--quiet]
/cva/scripts/cvaDiskUtil.py expand [--disk-size DISK_SIZE] DISK_SIZE can be in KB, MB, GB or TB
