Hi all, We're building a new OpenStack zone very soon. Our compute hosts are spec'd with direct attached disk for ephemeral instance storage and we have a bunch of other storage nodes for Ceph serving Cinder volumes.
We're wondering about the feasibility of setting up the compute nodes as OSDs and running a Ceph shared ephemeral storage pool across those nodes. We understand this implies some more resource overheads, but we tend to have plenty of CPU available on our compute nodes so don't anticipate a major issue there. Is anyone else doing this successfully, is there anything else to consider? Oh, and we're ICE customers, so would such a setup be supportable? Cheers, Blair
