Summary

You can move an instance and its attached data volume to another project which you or someone else manages. If there is no data volume, ignore the steps mentioning it.

This page:

Conceptually the process is as follows:

Create a snapshot of the instance root volume
Create a new volume from the snapshot
Transfer the data volume and new root volume to the other project
Create a new instance from the transferred root volume
- Note that because a new instance is created, it will have a different IP address to the original one
Attach the transferred data volume to the instance
Clean up

Procedure

Prepare

If you do not have project access to both the sending and receiving projects, arrange timing and details with the person on the other project
Ensure the sending and receiving projects have enough quota for the additional resources
- The sending project will be creating a snapshot and additional volume matching the root volume, typically 40GB
- The receiving project will be receiving the whole data volume, and creating an additional instance
You can ask for help with any details, via help@pawsey.org.au

Send - from source project

Shut down the instance, then detach the data volume
- From this point do not turn the instance on again in the source project
https://nimbus.pawsey.org.au/project/volumes/ in the Actions menu of the volume attached as /dev/sda or /dev/vda to the instance, Create Snapshot
https://nimbus.pawsey.org.au/project/snapshots/ Create Volume from the snapshot
https://nimbus.pawsey.org.au/project/volumes/ Create Transfer for the new volume and for the data volume
- This will provide two credentials files, which you should save and provide to the admin of the destination project

Receive - in destination project

https://nimbus.pawsey.org.au/project/volumes/ Accept Transfer to receive the root volume and the data volume
- Use the contents of the credentials files to accept these transfers
Once done, Launch Instance as if you are creating a new instance, with this setting
- Source page, Select Boot Source: Volume
- Select the transferred root volume
Attach the transferred data volume to the instance, and mount it
- sudo mount /dev/sdc /data
  - For instances created before May 2022: sudo mount /dev/vdc /data
- Do NOT mkfs to wipe the volume
- If the instance console shows errors mounting the data volume at boot time, you may need to attach the data volume then Soft Reboot Instance
Confirm that the instance is working as expected before proceeding
- In particular, configure ssh to suit your needs in the ~/.ssh/authorized_keys file

Clean Up

In the source project:

Delete the snapshot
Delete the instance
If you were granted additional quota in either project for the transfer, notify Nimbus admins so we can revert the temporary changes
