Hi all,
very interesting discussion here. I am facing the issue connecting my
Ceph cluster with Cloudstack via the RBD protocol. It seems like there
is either a documentation or software bug because we are running always
in the same error (rbd pool not found). I was thinking about creating a
NFS service on my Ceph cluster to connect it to Cloudstack because I
know that adding an NFS server as primary storage works. My cluster is
far smaller than yours but I am worry about performance and IOPS when
using NFS service with Ceph.

I second what he said, I've ran ACS zones with 60+ hypervisors and 2,000 VMs
from one single pair of storage servers delivering , all on NFS and no issues
at all.
Just be sure to select the right vendor and size it correctly.

Abishek,
NFS over a bunch of drives works just fine but has no means for failover (out
of the box, when self-built). If your benchmark shows enough IO performance per
VM, then NFS is just the way to go.
Keep in mind that NFS can have various backing store technologies like NetApp
appliances, Ceph, plain RAID volumes - it leads to different performance levels
and reliability guarantees. As for accessor, NFS is OK.

Hello Every One,
We are planning to go into cloud production with cloudstack 4.15 and
KVM host. We are currently considering nfs as storage because of the
performance. Is it feasible to use NFS as primary storage type in
production environment. Will there be any bottleneck of any offsets in
future(if any one has deployed nfs as storage in production). Shall I
prefer iscsi with NFS or any other storage type above NFS for
production environment.
Thank You.
