How To: Change the Location of a ZVOL on TrueNas Scale

https://www.truenas.com/community/threads/moving-a-zvol.76574/ 

 

 Log in to the TrueNAS server via SSH and elevate to the root user (if you are not already). 

 Run the zfs list command and look for the full path of the volume you would like to move. 

 Run the command  zfs snapshot -r path-to/your-zvol@relocate where @relocate is the name of the snapshot we are creating. 

 Run the command  zfs send path-to/your-zvol@relocate | zfs receive -v new-path/to-zvol 

 Wait for the command to complete. 

 Delete the original in the TrueNAS web UI
