Hi Marco, On 23 Nov 2017 7:05 am, "Marco Marino" <marino.mrc at gmail.com> wrote: Hi, I'm trying to configure drbd9 with openstack-cinder. Actually my (simplified) infrastructure is composed by: - 2 drbd9 nodes with 2 NICs on each node, one for the "replication" network (without using a switch) and one for the "storage" network. - 1 compute node with a dedicated NIC connected to the storage network - 1 controller with openstack-cinder-volume installed on it. Please, review the configuration at https://www.draw.io/# G1P2uJ9LoXc0bJdNRS9m2fN5cuik73t7_T My questions are: 1) Using the DRBD Transport, can I connect directly compute nodes to the drbd storage without passing through the cinder-volume node? 2) if yes, what I have to install on each node? I suppose: drbd9 kernel module + utils + drbdmanage on DRBD1 and DRBD2 drbd9 kernel module + utils on COMPUTE nodes drbdmanage on openstack-cinder-volume (???) 3) How should I configure openstack-cinder-volume in drbdmanage??? (External node or whatelse?) Please note that replication network and storage network are 2 different subnets! IPs I've used in drbdmanage when I created the drbd cluster belongs to the replication network. Is this correct? 192.168.10.0/24 = replication network 192.168.20.0/24 = storage network I'm sorry, but I'm a bit confused about this configuration Wouldn't you just install Cinder together with drbd on the drbd nodes? Then you just give cinder the drbd device for its lvm to serve block devices from via iSCSI as per usual. -------------- next part -------------- An HTML attachment was scrubbed...
