I noticed while reading through Mitaka release notes that vendordata_driver has been deprecated in Mitaka (https://review.openstack.org/#/c/288107/) and is slated for removal at some point. This came as somewhat of a surprise to me - I searched openstack-dev for vendordata-related subject lines

[Openstack-operators] Avoiding Cinder stampedes with RBD? (Kilo)

2016-03-22 Thread Ned Rhudy (BLOOMBERG/ 731 LEX)
We have a situation where tenant A is trying to launch large numbers of instances from a single RBD volume snapshot in Cinder (e.g., 40 instances at once). We made an unrelated change recently to enable rbd_flatten_volume_from_snapshot by default in order to save tenants who create large

Re: [Openstack-operators] RAID / stripe block storage volumes

2016-03-07 Thread Ned Rhudy (BLOOMBERG/ 731 LEX)
Hey Saverio, We currently implement it by setting images_type=lvm under [libvirt] in nova.conf on hypervisors that have the LVM+RAID0 and then providing different flavors (e1.* versus the default m1.* flavors) that launch instances on a host aggregate for the LVM-hosting hypervisors. I suspect

Re: [Openstack-operators] Nova-network -> Neutron Migration

2016-02-17 Thread Ned Rhudy (BLOOMBERG/ 731 LEX)
We're in mostly the same boat; using nova-network with VLAN segmentation and looking at a Neutron migration (though ours may take a more drastic path and take us to Neutron+Calico). One question I have for you: the largest issue and conceptual leap we had when initially prototyping

[Openstack-operators] Managing quota for Nova local storage?

2016-02-17 Thread Ned Rhudy (BLOOMBERG/ 731 LEX)
The subject says it all - does anyone know of a method by which quota can be enforced on storage provisioned via Nova rather than Cinder? Googling around appears to indicate that this is not possible out of the box (e.g., https://ask.openstack.org/en/question/8518/disk-quota-for-projects/).

2016-02-08 Thread Ned Rhudy (BLOOMBERG/ 731 LEX)
In our environments, we offer two types of storage. Tenants can either use Ceph/RBD and trade speed/latency for reliability and protection against physical disk failures, or they can launch instances that are realized as LVs on an LVM VG that we create on top of a RAID 0 spanning all but the OS
