| Hi,
No this must always be the same UUID. You can only specify one in cinder.conf.
Btw nova does the attachment this is why it needs the uuid and secret.
The first secret import generates an UUID, then always re-use the same one for all your compute node, do something like:
<secret ephemeral='no' private='no'>
<uuid>9e4c7795-0681-cd4f-cf36-8cb8aef3c47f</uuid>
<usage type='ceph'>
<name>client.volumes secret</name>
</usage>
</secret>
Cheers.

I am trying deploy Ceph RBD + OpenStack Cinder.
Basically, my question related to this section in documentation:
cat > secret.xml <<EOF
<secret ephemeral='no' private='no'>
<usage type='ceph'>
<name>client.volumes secret</name>
</usage>
</secret>
EOF
sudo virsh secret-define --file secret.xml
<uuid of secret is output here>
sudo virsh secret-set-value --secret {uuid of secret} --base64 $(cat client.volumes.key) && rm client.volumes.key secret.xml
Do I need tie libvirt secrets logic with ceph client.volumes user on each cinder-volume hosts? So it will be separate "uuid of secret" for each host but they all will use single user cinder.volumes, right?
Asking this because I have strange error in nova-scheduler.log on controller host:
