Forgive me by the off topic, but I wonder if someone here can point me
the performance difference between GlusterFS and Ceph...
Which one is faster? Why? Some docs or websites??
Thank you...

I tried Gluster, both native and it's NFS implementation. The NFS
worked great, until it didn't. It began to fail under load. The
Gluster native worked fine, but halved my IO. I was doing replicate
gluster, which sends data to all (in my case 2) bricks over the same
link, essentially reducing your speed. 2 bricks in replicate, half the
speed. 3 bricks, 1/3 of the speed.
Gluster NFS replicates it's data between servers, not between client and
server, and can be off-loaded to another network link.
I settled on standard kernel NFS with DRBD to replicate the data. I
changed the Proxmox config files to use NFSv4, and I am super happy.
