I have two storage servers (each with 50T, which I cannot physically transfer to the other) and I would like to make all this space available for volume creation.

I´m deplying through Kolla-Ansible and the sources are a bit contradictory on this. Some say that I can just put the following in globals.yml:

enable_cinder: "yes"
enable_cinder_backend_lvm: "yes"
cinder_volume_group: "cinder-volumes"

And list both nodes in the inventory under [Storage] (after creating a VG called "cinder-volumes" in each machine). The prechecks complain about a cinder_cluster_name, and setting it resolves the prechecks errors. But every documentation on "cinder_cluster_name" setting says that it won't work with LVM.

Anyone with experience putting cinder with more than one LVM cinder-volume? Will it create conflicts?

Hi all

One of the storage nodes on my OpenStack cloud has a fairly big raid 5 array, totaling 50T.

I'm new at managing such big capacities and a bit afraid of just creating a monstrous lvm volume that would make fsck and backup a nightmare.

So my question is, if I am to make a bunch of smaller volumes, what would be a decent compromise between cumbersome big and just too small?
