For 750 osd 5 monitor in redhat doc

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I went through some Redhat doc and saw this sentence which I didn't see in Ceph docs:

"The storage cluster can run with only one Ceph Monitor; however, to ensure high availability in a production storage cluster, Red Hat will only support deployments with at least three Ceph Monitor nodes. Red Hat recommends deploying a total of 5 Ceph Monitors for storage clusters exceeding 750 Ceph OSDs."

here:
https://docs.redhat.com/en/documentation/red_hat_ceph_storage/4/html/installation_guide/what-is-red-hat-ceph-storage_install#what-is-red-hat-ceph-storage_install

We will reach this number so wonder do we really need 5 mon?
Currently we have 3 collocated  mgr/mon on baremetal server with some multiste gw traffic, if needed I'd plan to simply add some mon on vm only.

Thank you
