[PVE-User] Trouble Creating CephFS

Hi All,

I'm testing ceph in the lab. I constructed a 3 node proxmox cluster
with latest 5.4-13 PVE all updates done yesterday and used the
tutorials to create ceph cluster, added monitors on each node, added 9
OSDs, 3 disks per ceph cluster node, ceph status OK.

>From the GUI of the ceph cluster, when I go to CephFS, I can create
MSDs, 1 per node OK, but their state is up:standby. When I try to
create a CephFS, I get timeout error. But when I check Pools,
'cephfs_data' was created with 3/2 128 PGs and looks OK, ceph status
health_ok.

I copied over keyring and I can attach this to an external PVE as RBD
storage but I don't get a path parameter so the ceph storage will only
allow for raw disk images. If I try to attatch as CephFS, the content
does allow for Disk Image. I need the ceph cluster to export the
cephfs so I can attach and copy over qcow2  images. I can create new
disk and spin up VMs within the ceph storage pool. Because I can
attach and use the ceph pool, I'm guessing it is considered Block
storage, hence the raw disk only creation for VM HDs. How do I setup
the ceph to export the pool as file based?

I came across this bug:
https://bugzilla.proxmox.com/show_bug.cgi?id=2108

I'm not sure it applies but sounds similar to what I'm seeing. It's
certainly possible I'm doing something wrong but I'm not seeing how to
get this working as needed. Any guidance is appreciated .

Thanks.
