Old NAS - SMB3 Multi-Channel

[strop]

Have an old DS1511+ that I use for backups which is working fine still but always seeking more speed.

Is there any way to get SMB3 Multichannel working on it or some other things you can do to take advantage of the multiple network connections?

You can but try to set it by editing smb.conf using vi or any other suitable editor:

root@Dragon:~# vi /etc/samba/smb.conf

root@Dragon:~# cat /etc/samba/smb.conf

    server multi channel support = yes
    aio read size = 0
    aio write size = 0
    printcap name=cups
    winbind enum groups=yes
    include=/var/tmp/nginx/smb.netbios.aliases.conf
    encrypt passwords=yes
    min protocol=SMB2_10
    security=user
    local master=no
    realm=*
    syno sync dctime=no
    passdb backend=smbpasswd
    printing=cups
    max protocol=SMB3
    winbind enum users=yes
    load printers=yes
    workgroup=WORKGROUP
root@Dragon:~#

# Then restart SMB via SSH or restart the NAS itself.

I have older NASes working with SMB 3, but nothing as old as a 2011.

Do you need to do any updates to SMB before you do this though?

 

[Robbie]

Depends on what SMB you have. We don't even know what DSM you have installed.

samba --version

Sorry, Not thinking and making assumptions. It is on the last version of DSM that was available for the unit. Nothing else updated either

DSM 6.2.4-25556 Update 7
Samba: Version 4.4.16

SMB3 MC was introduced in Samba v4.4 as an experimental feature, so you do have that capability.

MC was marked as experimental for ages but many of us ran it 'unsupported' Syno NASes for ages, with no negative consequences.

Thank you. Once I get the network figured out I will look at how I can do SMB Multichannel.
