Title:
stable/xena unable to attach multi-attach volume via "openstack nova
add volume"
Status in OpenStack Compute (nova):
Invalid
Bug description:
Dear all
I have encountered an error with Openstack Heat but I think this is
something that is also affecting (or even caused by) a possible issue
with nova.
Here my post for HEAT team
https://storyboard.openstack.org/#!/story/2010157
I have installed stable/xena using openstack-ansible and I am
operating several test vms in my ecosystem before to move to a
production stage. Currently I am using Cinder integrated with Ceph (if
you think it may be of any interest).
Just to summarize a possible test procedure (for convenience I simply use CLI
but with Horizon there is another workaround that I presented in the
storyboard's post above):
- create a multi-attach volume
- create 2 instances that potentially want to share the volume
- attach the volume to the first instance [it will work great!]
- attache the volume to a second instance... you should receive the following
error:
openstack server add volume <serverID> <volumeID> --device /dev/vdb
Multiattach volumes are only supported starting with compute API version
2.60. (HTTP 400) (Request-ID: req-5a60e72a-b7e2-49d6-81b2-c15753e054a2)
BUT
If I use the following command on the second attach:
nova volume-attach <serverID> <volumeID> auto
+-----------------------+--------------------------------------+
| Property | Value |
+-----------------------+--------------------------------------+
| delete_on_termination | False |
| device | /dev/vdb |
| id | c292cdd5-7dc5-4714-bdb3-a309e8416232 |
| serverId | 7b6a0651-f4cd-4018-a042-58f695ab73aa |
| tag | - |
| volumeId | c292cdd5-7dc5-4714-bdb3-a309e8416232 |
+-----------------------+--------------------------------------+
it works properly!
Is it expected because of some implementation task or is it a potential bug?
Actually I am able to create and use multi-attach volumes but only by
making manually the attachment with the commands reported above.
Thanks for your kind attention and looking forward to hear by you.
Best regards,
Davide
