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.
