Re: [Openstack-operators] [openstack-dev] Upstream LTS Releases

For those wondering why operators can’t always upgrade sooner, I can add a little bit of color: In our clouds, we have a couple vendors (one network plugin, one cinder driver) and those vendors typically are 1-3 releases behind ‘cutting edge’. By the time they support the version we want to go

Re: [Openstack-operators] Experience with Cinder volumes as root disks?

At Overstock we do both, in different clouds. Our preferred option is a Ceph backend for Nova ephemeral storage. We like it because it is fast to boot and makes resize easy. Our use case doesn’t require snapshots nor do we have a need for keeping the data around if a server needs to be rebuil

Re: [Openstack-operators] Any serious stability and performance issues on RBD as ephemeral storage ?

Vahric - We use Ceph for nova ephemeral as well on thousands of VMs and we love it. Fast provisioning of VMs, solid, reliable and flexible. Works great with live-migration. The only time we ever have a problem is an OSD is allowed to get too full. Never let that happen! Mike Smith Lead

Yeah, I saw that in his response. Sounds like a good option if you want to try it. I hadn’t tried it only because I didn’t know about it at the time, and the older version was working fine for us on our other hosts. Mike Smith Lead Cloud Systems Architect Overstock.com<http://overstock.

Hi Adam - The OS of the guest is independent of the Openstack version. Your choice of hypervisor (KVM, VMWare, HyperV, etc) would just need to support the OS version that you want to run on your guests. Mike Smith Lead Cloud Systems Architect Overstock.com<http://overstock.com> On

Re: [Openstack-operators] Blazar? (Reservations and/or scheduled termination)

Yes, at Overstock our users don't provision instances directly out of horizon or nova. They use an orchestration tool we wrote in Django which among other things tracks a lease time, warns users about expiration, allows them to extend etc. Works great for us, but the same approach may not work
