Dump question:  why should i use a block storage replacing nfs?
Nfs-ganesha makes use of libgfapi, block storage does the same but also
need the whole iscsi stack so performance could be lower

If i don't need direct access to a block device on the client (in example
for creating custom FS or LVM and so on), the nfs ganesha should be a
better approach, right?

Anyone compared performances between:

1. Fuse mount
2. Nfs
3. Nfs ganesha
4. Qemu direct access via gfapi
5. Iscsi

?
