Renaming volumes on Ceph RBD

LXD
1

I’m trying to figure out if this is a bug or expected behaviour.

lxc storage volume rename test-pool volume2 volume3
Error: Invalid expanded devices: Storage volume "maran-test" is already attached to a container on a different node

Note that “maran-test” is not related to the container volume2 is currently mounted on, it does not even live on the same pool.

Container the volume is attached on.

Any idea why it won’t allow me to rename volumes?

What LXD version is that?

And can you also show the lxc storage volume show for that maran-test volume?

This is on master d1a99e0138815b80be6a894a92fe5fec7970125c.

Definitely smells like a bug, can you file one at https://github.com/lxc/lxd/issues
ideally with as short a reproducer as you can come up with?

I tried to replicate it on the latest master but I can’t seem to build it any longer.

# github.com/lxc/lxd/lxd/cluster
lxd/cluster/recover.go:67:14: server.Recover undefined (type *dqlite.Node has no field or method Recover)

I already cleared my deps folder and did a make deps but it still won’t build. Any hints?

Edit

Solved it, makefile does not update go dependencies automatically but there is a nice update script make update.

Edit 2

Still happening on latest master, issue created.
