Thanks Mike , Thanks for sharing VM From: Mike Smith <mism...@overstock.com> Date: Saturday, 10 December 2016 at 08:22 To: Vahric Muhtaryan <vah...@doruk.net.tr> Cc: David Medberry <openst...@medberry.net>, "openstack-operators@lists.openstack.org" <openstack-operators@lists.openstack.org>, "m...@mattjarvis.org.uk" <m...@mattjarvis.org.uk> Subject: 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!
