Multichannel SMB/NFS?

[BloodyIron]

Hi Folks,

I suspect the devs might be able to better answer this, but here goes.

What's the current state of Multichannel support for SMB/NFS in Proxmox VE?

SMB 4.4 added an experimental version of SMB multichannel, but people have been reporting a good amount of success.

NFS 4.1 added multichannel technology too, and also success stories are there.

Now, why am I asking this at this point in time? Because it's currently looking like FreeNAS v10 is going to get support for BOTH technologies, and FreeNAS is very important to my/our infrastructure.

Proxmox VE is also important to our infrastructure, and as such multichanneling for both protocols is something we're very interested in (for different reasons for each).

Any plans for Proxmox VE to implement at least NFS multichanneling? Perhaps some hope for SMB multichanneling too? Do let me know

NFS 4.1 is possible, you need to mount it by hand

mount -t nfs -o nfsvers=4.1[...]

or edit a PVE file somewhere. Multipathing should work as well, you should try:

#mount the NFS4.1 shared folder on a local folder
mkdir vmimages
#Establish first connexion and session
mount -tnfs4.1 -ominorversion=1 192.168.1.3:/home/testnfs vmimages
#Agregate second connexion to the session
mount -tnfs4.1 -ominorversion=1 192.168.2.30:/home/testnfs vmimages

I don't know about SMB thoug, sorry.
