Remote doesn't exist

1

So I am back in the lab and trying to move a snapshot to another machine. Bear in mid i don’t have a third cluster member in the lab (not advised but there is a sincere lack of resources for the lab).

sarlacpit@lxd02:~$ lxc info isp-test2
Name: isp-test2
Location: lxd02
Remote: unix://
Architecture: x86_64
Created: 2020/08/21 13:05 UTC

Profiles: vlan2007-isp
Snapshots:
  snap0 (taken at 2020/08/21 15:17 UTC) (stateless)

sarlacpit@lxd02:~$ lxc copy isp-test2/snap0 lxd01:isp-test3 --verbose
Error: The remote "lxd01" doesn't exist

 lxc cluster list

So two questions:

  1. What is the difference between a remote & a cluster machine?
  2. Why do I get the error (is it because of a lack of a remote?) both servers have a local (default) remote.

Also, I created the container ‘isp-test2’ from the command line of lxd01 though it added it to lxd02 as a default.

Something screwy is afoot - it is probably me - I would appreciate any assistance

Thanks

lxc copy isp-test2/snap0 isp-test3 --target lxd01 is what you want in this case.

lxc remote list shows you your remotes.
lxc cluster list shows you your cluster members.

For LXD a remote is a distinct LXD deployment, so you’d be using a different remote if copying to another cluster. When dealing with internal cluster placement, target is the way to go.

Thanks again for your valuable time i really appreciate it.
