Steps to copy data from a volume storage

Summary

The customers cannot copy data from a volume storage because the machine is unavailable, and the volume clone is not working. Billing continues.


Solutions

  1. Download the latest Vast CLI from GitHub

wget https://raw.githubusercontent.com/vast-ai/vast-python/master/vast.py -O vast; chmod +x vast;

Note: It is recommended to refrain from using the pip install vastaiVast command, as it does not correspond to the latest version and may not function correctly with the volume copy feature.


  1. Search for an available machine using the CLI command search offers


Example:

./vast search offers "gpu_name=RTX_3060 num_gpus=1 rentable=true"

Note: It is essential to search for an available machine to ensure that the new volume we are about to create below can be successfully mounted to an accessible instance.


  1. Search for an available volume storage using the CLI command vastai search volumes


Example:

./vast search volumes "disk_space>=20 machine_id=31810"
ID        CUDA  cpu_ghz  Disk B/W  Disk  Disk Name  $/Gb/Month  NV Driver   Net_up  Net_down  R     Max_Days  mach_id  status    host_id  country

  1. Create a new volume using create volume


Example:

./vast create volume 29372443

Note: It is necessary to create a volume that is not mounted to any instances first; otherwise, the copy command may not function properly.


  1. Copy data from the old volume to the new one using copy


Example:

./vast copy V.34167645:/ V.29372443:/
copying V.34167645:/ V.29372443:/
Remote to Remote copy initiated - check instance status bar for progress updates (~30 seconds delayed).


  1. After the data has been successfully copied to the new volume, the new volume can be mounted to a new instance.
