Support for CephFS via NFS (NFS-Ganesha)

[Toranaga]

@alexskysilk
Thank you for the link.

You shall not debug my systems or google for me.
I just told about my problems and hoped that somebody had the same problems solved already.
Sometimes you get an answer, sometimes not.
Call it smalltalk.

How so? that's actually the preferred method as it will allow you to isolate the fileserver from your hypervisor; if you are not using proxmox for, well, proxmox- yes, by all means, use a different distro. remember, in this case both the proxmox node and vm act as guests for cephfs in the same manner.

I was talking about the fact that ceph supports nfs.
So why use another vm to expose cephfs via nfs when ceph+ganesha can do that ? Maybe just to have some isolation, but if everything is internal then i dont really see a problem using ceph+ganesha directly.

Hi,
you could have a look at my journey for NFS - CephFS on Proxmox...
https://forum.proxmox.com/threads/ha-nfs-service-for-kvm-vms-on-a-proxmox-cluster-with-ceph.80967/

As far as I understand the bugs I encountered should be solved by now in the stable NFS Ganesha version 4 series...

Thats not how that works.

ceph does NOT support nfs.

nfs-ganesha has vfs object support for cephfs, which can be brought to bear from any cephfs connected guest- which can be your proxmox host, sure- but its not a good idea to use it for that.
