<div dir="ltr">Andrew, <div><br></div><div>Thanks for the reply and sorry it took me so long to respond. Are there any specific options that fuel uses when it deploys the ceph osd's? If so, do you know what configuration files, I suspect the puppet manifests but I'm trying to verify, those commands are kept in? It would seem to me that if all that's needed to add dm-crypt afterwards is to remove the osds and re-add them then modifying the actual commands that fuel uses should work as well. However, I'm not familiar enough to know what files need to be modified for those changes to take effect during a deployment.</div><div><br></div><div>The two questions I asked are sort of related. I was asking about dm-crypt for disk end-of-life and warranty replacement. It would be good to know that any data on a disk is fully encrypted in these circumstances. </div><div><br></div><div>I'm not particularly familiar with federated gateways and I was wonder if it would work to do offsite replication and backup of our ceph storage. We'd hopefully be doing daily backups and we need something that can facilitate that. I thought federated gateways might be an option to have some ceph nodes in a separate location. We've also been considering using rbd to do incremental snapshots as outlined in [1].</div><div><br></div><div>Any additional insight on these ideas would be much appreciated.</div><div><br></div><div>Forrest</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Nov 10, 2015 at 9:01 PM, Andrew Woodward <span dir="ltr"><<a href="mailto:xarses@gmail.com" target="_blank">xarses@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><p dir="ltr">Sent too soon, I'd be interested in what all you are attempting to accomplish and see how we might be able to design and add support for this</p><div class="HOEnZb"><div class="h5">

Both can be accomplished post deployment manually however. For dm-crypt you can remove the osd and Re add it using ceph-deploy (you will want to update the partition GUID to match this usage for automatic mounting )</p>
<p dir="ltr">For topology changes, I'd just refer to the crush map documentation.</p>

Does anyone know how to use Fuel to enabled dm-crypt for ceph and if so what sort of performance hit you take when doing so? What about having multi-site ceph nodes for offsite backup? Would using federated gateways be a workable option or is there a better way to deal with of off-site redundancy/backup? Thanks,</div><div><br></div><div>Forrest</div></div>
