Re: Ceph orch placement - anti affinity

If you don't specify "count_per_host", the orchestrator won't deploy multiple daemons on one host. There's no way (that I'm aware of) to specify a primary daemon. Since standby daemons need to be able to take over the workload, they should be all equally equipped.

Zitat von Kasper Rasmussen <kasper_steengaard@xxxxxxxxxxx>:

Let’s say I have 2 cephfs, and three hosts I want to use as MDS hosts.

I use ceph orch apply mds to spin up the MDS daemons.

Is there a way to ensure that I don’t get two active MDS running on the same host?

I mean when using the ceph orch apply mds command, I can specify —placement, but it only seems like I can define the hosts, but not let’s say a primary host or something similar.

Anyone with knowledge of how to do this or is it simply not possible?
