Hi,
as always the answer is "it depends". Our company uses the ceph
cluster for all three protocols. We have an openstack cluster (rbd)
and use cephfs for work and home directories, and radosgw for k8s
backups. And we don't face any performance issues. I'd recommend to
give cephfs a try, no need to add a gateway inbetween as a potential
bottleneck, unless any policies require so.
Regards,
Eugen

Hi all,
i am planning to set up on my ceph cluster an RBD pool for virtual
machines created on my Cloudstack environment. In parallel, a Ceph
FS pool should be used as a secondary storage for VM snapshots, ISOs
etc. Are there any performance issues when using both RBD and CephFS
or is it better to use a separate NFS server? Moreover, when setting
up Ceph NFS using ceph orch, only one host is "registered" from
which i can mount the Ceph FS. Should I use more than one host (e.g
high-availability nfs)? Any suggestions?
Best,
Mevludin
