I have a 64bit 12.04 server with a raid 6 array.
I have setup NFS and SAMBA shares.
If I copy any files over NFS from client to server - the speed of the copy is ridiculously low - around 1-2MB/s If I copy to the same folder being shared over SAMBA - I get 45-50MB/s
However, if I copy a group of folders that exceed 10GB over either connection the server will just drop of the network and I cannot access it via ssh or any other means.
I am unable to use:
sudo ifconfig eth0 up/down
to reset the nic interface - the only option is to power down and restart the server.
If anyone can point me to any logs to check for what is causing the error or help to diagnose I would be much appreciated as this makes my server pretty much useless.
