DESTINATION PATH TOO LONG – ERROR

We are in 2024, entering into 2025, and most people still suffer from this ridiculous error, even after enabling long file names in GPEdit and also in the Registry.



To get around it, use ROBOCOPY

Open a command prompt as administrator

cd into the directory you want to copy from

know the path to the directory you want to copy the files to.

execute the command

the format will look like this:
robocopy . “D:\DestinationDirectory” /E /COPYALL /R:0

robocopy .
means robocopy everything in this directory and its sub directories

CONFIGURE NFS ON A SYNOLOGY

Here is how I configure NFS on my synoloy so that I can copy files from my synology over to my Ubuntu 22.04 AI system that uses a JBOD

Login into your synology

Click Control Panel

Click File Services

Select the NFS Tab at the top

Place a checkmark next to Enable NFS

I use NFSv3

Then Click Apply or Save/

Go back to Control Panel

Then select Shared Folder

Click on the Share that you want to Enable NFS on

Click Edit

Then click NFS Permissions

Select Create

Type in the IP for your Ubuntu 22.04 computer and make sure the rest of the settings are set just like the picture here:

Click Save

Then on your Ubuntu box you will want to

Open a Terminal

sudo su –

cd /mnt

sudo mount -t nfs 192.168.1.100:/volume1/Folder /mnt/synology

replace Folder with your actual folder, and use the ip of the share you want to copy from

cd /mnt/synology

cp -R -v /mnt/synology/* /media/ubuntu/JBOD\ Disk\ 5/

this will copy everything from the synology folder that is connected to your synology, and it will place it into JBOD disk 5 (change the paths to whatever you need for you)

WINDOWS 11 CONFIGURE JUMBO FRAMES

I have jumbo frames enabled on my Physical wired connection because I only use that for large data transfers, otherwise all my traffic is wireless.

Here is how I enabled Jumbo Frames

Right Click on Network Connections

Select Properties

Select the Physical NIC

Right Click and go to Properties

Click the Configure Button

Select the Advanced Tab

Scroll to Jumbo Frames and select it

Set the value to 9014 Byte

Thats it. It is enabled.

SPEED UP YOUR SYNOLOGY WITH THIS

By default your MTU is 1500. Here is how you increase it to 9000 to enable Jumbo Frames, with no network impact. It will speed up your system because it does not have to repeatedly send the header info on every small packet.

Login into your Synology

Go to Control Panel

Select Network

Then go to Network Interface

Select Lan 1

Then press Edit

Checkmark MTU and set the value to 9000

Click Ok

Click Yes

Then do the same for Lan 2

Thats it. You now have jumbo frames

UNABLE TO ADD MOVIES TO PLEX ON A SYNOLOGY

This is a common issue when you first install the synology.

To fix it you simply need to allow the proper permissions on the Share.

Log into your synology

Click Control Panel

Edit your Shares

And set the permissions as shown here:

Plex needs Read/Write access

Save it

Now you can go back to your Synology Plex App

Add the library

You will most likely find your files in Volume 1 \ Plex

FASTEST WAY TO COPY FILES BETWEEN TWO SYNOLOGY NAS DEVICES

Windows is slow…takes weeks to copy 15TB between two devices if you use explorer. Here is how you copy the files in hours instead of weeks.

On your Windows 11 computer

Open Explorer

Navigate to Synology 1

Map a Drive from your Windows 11 pc to the Synology Share
ex. Drive X will be \\Synology1\Share

Now do the same for Synology 2 and the share you want to map.
ex. Drive Y will be \\Synology2\Share

On your Windows 11 pc, now open PowerShell (not as Administrator, just open PowerShell)

Type:
robocopy ‘X:\FolderYouAreCopyingFrom’ ‘Y:\FolderYouAreCopyingTo’ /S /E /MT:32 /NFL /NDL /NJH /NJS

example: robocopy ‘X:\SourceCode\Documents’ ‘Y:\NewSourceCodeRepo\Documents’ /S /E /MT:32 /NFL /NDL /NJH /NJS /V

You will copy thousands of files per second over a 1GbE network

DOCKER ON VMWARE ESXI

By default you cannot run it here.

However if you:

Shutdown the VM

Browse to the VM’s folder within VMWare’s Datastore Browser

Download the VM’s .vmx file

Open it with a text editor

add this to the bottom:
vhv.enable = “TRUE”

Save the file

Upload it back to the storage manager and overwrite the original .vmx

Power the VM back on, it will now work

UPGRADE PORTAINER COMMUNITY EDITION ON DOCKER / / RASPBERRY PI

Here is a quick how-to for the way I updated my portainer to the latest

SSH to the Raspberry Pi 5

login

sudo su –
docker stop portainer
docker rm portainer
docker pull portainer/portainer-ce:latest
docker run -d -p 8000:8000 -p 9443:9443 –name=portainer –restart=always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:latest

Open a browser, navigate to your Raspberry Pi 5:9443 and then login

Success!

RUNNING OLLAMA ON UBUNTU 24.04 WITH NVIDIA GPU

Here is a quick step by step.

Install Ubuntu 24.04 Desktop. At the time Ubuntu Server 24.04 has issues. So run this on Desktop

Login and open a terminal
sudo su –

apt-get update

apt-get upgrade

nvidia-smi
(this should show you your NVidia GPU. These drivers work well. Keep them)

apt install curl

curl -fsSL https://ollama.com/install.sh | sh

If it errors, run it a second time. It fixes the error.
curl -fsSL https://ollama.com/install.sh | sh

sudo systemctl enable ollama.service

sudo systemctl start ollama.service

ollama pull llama3:8b

ollama run llama3:8b

Open a new terminal
watch -n 0.5 nvidia-smi
You can see the GPU work

Back in the LLama2 terminal
ctrl +c
this will kill the session

Add Docker’s official GPG key by selecting below and pasting it into the terminal:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

echo \
“deb [arch=$(dpkg –print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
$(. /etc/os-release && echo “$VERSION_CODENAME”) stable” | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

After the key installs:
apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

docker run -d –network=host -v open-webui:/app/backend/data -e OLLAMA_BASE_URL=http://127.0.0.1:11434 –name open-webui –restart always ghcr.io/open-webui/open-webui:main

sudo docker ps

Now open a browser and go to localhost:8080

Signup and create an account. this will be the administrator

Back in the Terminal, setup other modes:
ollama pull codegemma

ollama pull llama2:70b

ollama pull llama3:70b

ollama pull llama3

ollama pull dolphin-llama3:8b

ollama pull dolphin-llama3:8b-256k

ollama pull dolphin-llama3:70b-256k

ollama pull dolphin-llama3:70b-256k

ollama pull dolphin-llama3:70b

ollama pull llava

Now go and have fun
