Yes, with Rook this is possible by adding zone anti-affinity for the MDS pods. Travis On Tue, Oct 29, 2024 at 3:35 PM Gregory Farnum <gfarnum@redhat.com> wrote:
No, unfortunately this needs to be done at a higher level and is not included in Ceph right now. Rook may be able to do this, but I don't think cephadm does. Adam, is there some way to finagle this with pod placement rules (ie, tagging nodes as mds and mds-standby, and then assigning special mds config info to corresponding pods)? -Greg

I hope someone of the development team can share some light on this. Will search the tracker if some else made a request about this.

Hi,
I'm not aware of any service settings that would allow that.
You'll have to monitor each MDS state and restart any non-local active MDSs to reverse roles.
Regards, Frédéric.

Hi all We deployed successfully a stretched cluster and all is working fine. But is it possible to assign the active MDS services in one DC and the standby-replay in the other?
We're running 18.2.4, deployed via cephadm. Using 4 MDS servers with 2 active MDS on pinnend ranks and 2 in standby-replay mode. _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
