Hey I'm trying to mirate a volume from one node to another , one is the host and the other is the node . I'm running this command

cinder migrate 95adcbd2-3ca9-47f4-8cf4-7cb0ddd6cfe7 celestial12@lvmdriver-1

There is no error returned , but when I run

cinder show 95adcbd2-3ca9-47f4-8cf4-7cb0ddd6cfe7

It is still in the same host , and also

os-vol-mig-status-attr:migstat  : None

PS this is my host list when I run

cinder-manage host list

celestial3                          nova           
celestial3@lvmdriver-1      nova           
celestial12                         nova           
celestial12@lvmdriver-1     nova

with some warnings of packages

I also tried to look at the wireshark packet transfer , so if I could notice any packets transferring from my system , I couldn't link up with wireshark .

Please Help :)

What does cinder-scheduler logs say? This is likely to be happening because 'celestial12@lvmdriver-1' is not capable of handle the new volume.

Are you trying to migrate a root volume? As in a VM's primary Storage? If so cinder Migrate will not work.

I solved the issue , the only missing part was #lvmdriver-1

so my command was like

cinder migrate 95adcbd2-3ca9-47f4-8cf4-7cb0ddd6cfe7 celestial12@lvmdriver-1#lvmdriver-1

But in official documentation doesn't say anything like this , this worked for me but :) , I still don't know why and what's the internal working when i add that
