Are you coping over wifi or wireless?
What sharing technology are you using?
What OS is the server and the client running?

Thanks

Thanks as always, Actionparsnip.

I am using wired, not wireless.

Sharing is with Samba v 2:3.6.3-2ubuntu2.6
I have a Kubuntu 12.04 machine running open-iscsi v 2.0.871-0ubuntu9.12.04.1

The this machine has 2 nics, one on a 192.168.0.xxx for the LAN and the drobo runs connected to the iscsi lan on 192.168.2.xx therefore samba shares can be set up using the Kubuntu machine as a server however the issue with copying seems to be between the Kubuntu machine directly to the drobo.

192.168.0.x LAN --NIC0-- Samba ---- Kubuntu --NIC1-- 192.168.2.x ISCSI -- Drobo

apologies eth0 is 192.168.2.x and eth1 is 192.168.0.x

As you are using Linux on both sides, have you tried installing openssh-server on the Kubuntu box and using SFTP using nautilus as a client. It is also secure so can be used over WAN.

I can certainly try. Haven't set that up before but I can try it.

I'm just wondering if I've made it clear that files are being transferred directly across the iscsi connection from the drobo to the Kubuntu box, not thro' Samba?

I would add that I'd like to find out where the issue is. Does the info from the log give any clues?

Thank you I will check it out. Will respond in a couple of days.

Well, there's a first time for everything. I think I've compiled the driver and it's installed. There was a warning message when I compiled it. I'll reboot and see what happens.

fred@ubuntu:/Data/Packages/MarvellYukonDriver/Linux_v10.93.3.3/DriverInstall$ sudo bash ./install.sh

Installation script for sk98lin driver.
Version 10.93.3.3 (Aug-22-2012)
(C)Copyright 2003-2012 Marvell(R).
====================================================
Add to your trouble-report the logfile install.log
which is located in the DriverInstall directory.
====================================================

1) installation 3) generate makefile
2) generate patch 4) exit
Choose your favorite installation method: 1

Please read this carefully!

This script will automatically compile and load the sk98lin
driver on your host system. Before performing both compilation
and loading, it is necessary to shutdown any device using the
sk98lin kernel module and to unload the old sk98lin kernel
module. This script will do this automatically per default.

Please plug a card into your machine. Without a card we aren't
able to check the full driver functionality.

Do you want proceed? (y/N) y

IMPORTANT INFORMATION!

We found an alternative driver for your Marvell product on this system.
The alternative driver is _NOT_ directly supported by Marvell and does not
include all features provided by your device. If you want to use the
sk98lin driver developed by Marvell, you may choose either to deactivate
or remove the alternative driver.

[PRESS ANY KEY FOR FURTHER INSTRUCTIONS]

Do nothing:
  - The sk98lin will be installed
  NOTE: It may happen that the alternative driver will be loaded on
  the next boot process. In this case the Marvell driver _WON'T_ be
  loaded.

Deactivate driver:
  - The alternative driver will be renamed to _skge.ko or _sky2.ko
  - All references in the /etc/modprobe.conf file will be changed to
    the sk98lin driver
  - The alternative driver will be unloaded
  - The sk98lin driver will be installed

Remove driver (recommended):
  - The alternative driver will be removed from your system
  - All references in the /etc/modprobe.conf file will be changed to
    the sk98lin driver
  - The alternative driver will be unloaded
  - The sk98lin driver will be installed

1) Do nothing
2) Deactivate diver
3) Remove driver

Well, that looks good thanks!

I've just copied >30GiB of files and it hasn't hung. I'm copying another 242GiB across the network so that'll give me confidence if it works.

Thanks for the help!
:)

Thanks Thomas Krüger, that solved my question.

Well, 250GiB copied fine so it looks to be reliable. Great stuff.
