Hi,
we are migrating from a VMware ESXi setup with a NetApp NFS based shared storage.
We also did use NFS filesystems for mounts like /home or /root and application filesystems like a shared /var/www within our virtual machines and host-specific filesystems like /var/log.
Most of our VM-specific filesystems have been migrated to disks attached to the virtual machines now, but we are still wondering on how to migrate our shared filesystems.
Ideas:
Best regards
Rainer

Ideas:
- Mount Cephfs from the Proxmox VE Ceph Storage (is this supported?) and fiddle around the the Cephx keys and such
- Create three VMs, install Ceph and Cephfs on top of the Ceph RDB disks of Proxmox VE and mount Cephfs with in the VMs
- Create a single Debian Container on one of the nodes, install NFS kernel server there and export Cephfs directories. No HA and a downtime if we have to service the Proxmox VE host.
- Create a single Debian KVM VM, install NFS kernel server and export a disk. No HA - if we reboot the VM the NFS clients stall on the shared filesystem.
- Create two Debian KVM VMs, one disk for OS each and one shared disk between them. On that shared disk use OCFS2 and create a heartbeat active-passive NFS server.
- Create three Debian KVM VMs or CTs, install NFS Ganesha there and export CephFS directories over these.
Best regards
Rainer
