There is a policy config in this doc from the Apollo Cluster I have in provo.

Hi *.

I tried to understand the way how the policy.cfg needs to be filled and how the disk configuration should be configured - but it seems I am missing something and need help and an example to understand this ;-).

Maybe someone can create and share a policy.cfg and some examples for the disk configuration for me that matches somehow my scenario?

My scenario:
----
5 servers: ses-4-admin, ses-4-1,ses-4-2, ses-4-3, ses-4-4

ses-4-admin should get openAttic

ses-4-{1..3} should be a "MON"

ses-4-{1,3} should be a "iSCSI Gateway" where the iSCSI gateway IP is the third IP on each host (separate interface)

ses-4-{2,4} should be two hosts for the same "Rados Gateway"

ses-4-{2..4} should be "MDS"

ses-4-{1..4} should be OSD host

Each OSD host has 24 disks. 4 SSDs (sd{a..d}) and 20 SAS (sd{e..x}).
Always 5 OSDs should get the journal on one SSD - i.e. sde/sdf/sdg/sdh/sdj should get 20 GB journals on sda.
----

So what exactly do I need in my policy.cfg and how do I configure the disks properly?

P.S. I also want to create some pools (replicated and erasure), setup cache tiering, create RBDs and configure them with the iSCSI gateways... do I get it right that this is not yet available in DeepSea?

Thanks for any help,
Martin
