[Openstack] [nova] How nova deals with the attached volumes after the server being resized?

[王盼|2076]

Hi All,

I saw that nova doesn't do anything with the attached volumes on the server in 
the essex version, and when I tried to resize a server with a volume attached 
on the server's  /dev/vdc device, this volume disappeared after resizing(by 
virsh dumpxml), but I can get the volume is in-use by nova volume-list.

What I want to ask is that, should we detach the volumes before resizing a 
server and reattach it after resized?

If anything is wrong above, welcome to correct it.

Thanks in Advance

Best Regards,

Yes, you will have to manually detach and reattach volumes before using a 
resize in essex.
