TrueNAS with NFS<\/li>\n<\/ul>\n\n\n\nQuite an intricate setup just to download some files, huh? Yeah, but it solves the problem of both storing the files and freeing up my computer at the same time.<\/p>\n\n\n\n
The actual setup<\/h2>\n\n\n\n In my homelab I have a host running Proxmox for all of my local workloads. This runs several VMs (Virtual Machines) which again runs different OSes for different purposes. One of them is a Ubuntu Linux VM running several Docker containers. This is not a tutorial on either Linux, Proxmox or Containers. Only a description on how I use them. If you need to learn what a Docker is, please do read up on it and maybe continue to read this article after that?<\/p>\n\n\n\n
So why am I rambling on about Linux when Azure and AzCopy are both Microsoft technologies. As it turns out, Microsoft loves Linux. So much they’ve actually made a version of AzCopy for Linux! How neat! And the best part: I can run it in Docker! (Links to all the resources at the bottom of this article).<\/p>\n\n\n\n
Therefore I mounted up a NFS share on that Linux VM to my NAS running TrueNAS. Made sure I could both read and write to that share. Then I used PowerShell to create a SAS token for that disk in Azure so it could be exported. Please note that exporting a disk in Azure makes it unusable until either you release it from export manually or the SAS-token expires by itself!<\/strong> <\/p>\n\n\n\nNext was to run the Docker and hope for the best. And, it worked! It ran as it should, downloading the VHD to NAS. And via Tmux I could leave the session, leave the house with my laptop and return some time later and joining the same session and confirming it has finished. Good times.<\/p>\n\n\n\n
Wanna know how you can do it too? Sure, I’ll show you<\/p>\n\n\n\n
Step 1: TrueNAS<\/h2>\n\n\n\n You are not limited to TrueNAS, of cource. But this is my example and you should use what you want.<\/p>\n\n\n\n
First i created a NFS share on my NAS:<\/p>\n\n\n
\n
In the file structure on your NAS, choose a sufficient placement:<\/p>\n\n\n
\n
Make sure you set some user rights on this share. And it’s nice to actually limit what machines can acces it, so I set the IP to my VM to be the only machine allowed to communicate with this:<\/p>\n\n\n\nClick «Add» in the top right corner and it should be set. Cool, now you have to copy the path as we need in the next step when we are mounting NFS on Linux:<\/p>\n\n\n
\n
Step 2: Prepare your Linux environment<\/h2>\n\n\n\n Now for some nerdy Linux stuff in the command line! Log into your box and make sure you have NFS-support and Tmux installed:<\/p>\n\n\n\n
Bash<\/span><\/path><\/path><\/svg><\/span>sudo<\/span> <\/span>apt<\/span> <\/span>update<\/span><\/span>\nsudo<\/span> <\/span>apt<\/span> <\/span>install<\/span> <\/span>nfs-common<\/span><\/span>\nsudo<\/span> <\/span>apt<\/span> <\/span>install<\/span> <\/span>tmux<\/span><\/span><\/code><\/pre><\/div>\n\n\n\nThis will make sure both are in place. After that, we want to make a folder to mount our NFS share to. I used this method:<\/p>\n\n\n\n
Bash<\/span><\/path><\/path><\/svg><\/span>sudo<\/span> <\/span>mkdir<\/span> <\/span>\/mnt\/nfs_client<\/span><\/span>\nsudo<\/span> <\/span>mount<\/span> <\/span>-o<\/span> <\/span>hard,rsize=<\/span>1048576<\/span>,wsize=<\/span>1048576<\/span>,timeo=<\/span>600<\/span> <\/span>10.0<\/span>.0.204:\/mnt\/Pool4TBdisks\/NAS<\/span> <\/span>\/mnt\/nfs_client\/<\/span><\/span><\/code><\/pre><\/div>\n\n\n\nThis first creates a folder under \/mnt caled nfs_client. Then it mounts the \/mnt\/Pool4TBdisks\/NAS-share of my NAS, which is on IP 10.0.0.204 to that folder.<\/p>\n\n\n\n
Did it Work? Test it!:<\/p>\n\n\n\n
Bash<\/span><\/path><\/path><\/svg><\/span>cd<\/span> <\/span>\/mnt\/nfs_client<\/span><\/span>\nsudo<\/span> <\/span>mkdir<\/span> <\/span>Testfolder<\/span><\/span>\nls<\/span> <\/span>-la<\/span><\/span><\/code><\/pre><\/div>\n\n\n\nThis should output no errors, and show you that a folder with name «Testfolder» exists on the NAS. Good! Now we can move on over to Azure and prepare what we need to download!<\/p>\n\n\n\n
Step 3: Prepare Azure<\/h2>\n\n\n\n We can use PowerShell for this. Modules needed for this guide:<\/p>\n\n\n\n
\nAz.Accounts<\/li>\n\n\n\n Az.Compute<\/li>\n<\/ul>\n\n\n\nYou could<\/em> also browse the Portal and find the names for the resource group and the disks, but I will show you how to PS it! Connect to Azure:<\/p>\n\n\n\nPowerShell<\/span><\/path><\/path><\/svg><\/span>Connect-AzAccount<\/span><\/span><\/code><\/pre><\/div>\n\n\n\nRemember to authenticate with a user that has the right permissions to the subs and resources you need. If you have more than one Subscription in your tenant, you will get a notification for that. It will use the first one you have access to by default.<\/p>\n\n\n\n
In case you have more than one subscription available, get a list over the subscriptions:<\/p>\n\n\n\n
PowerShell<\/span><\/path><\/path><\/svg><\/span>Get-AzSubscription<\/span><\/span>\n<\/span>\nName Id TenantId State<\/span><\/span>\n----<\/span> <\/span>--<\/span> <\/span>--------<\/span> <\/span>-----<\/span><\/span>\nSubscription1 yyyy<\/span>-<\/span>yyyy<\/span>-<\/span>yyyy<\/span>-<\/span>yyyy aaaa<\/span>-<\/span>aaaa<\/span>-<\/span>aaaa<\/span>-<\/span>aaaa Enabled<\/span><\/span>\nSubscription2 xxxx<\/span>-<\/span>xxxx<\/span>-<\/span>xxxx<\/span>-<\/span>xxxx aaaa<\/span>-<\/span>aaaa<\/span>-<\/span>aaaa<\/span>-<\/span>aaaa Enabled<\/span><\/span>\nSubscription3 zzzz<\/span>-<\/span>zzzz<\/span>-<\/span>zzzz<\/span>-<\/span>zzzz bbbb<\/span>-<\/span>bbbb<\/span>-<\/span>bbbb<\/span>-<\/span>bbbb Enabled<\/span><\/span><\/code><\/pre><\/div>\n\n\n\nIf you need to switch subscription, you can do it like this:<\/p>\n\n\n\n
PowerShell<\/span><\/path><\/path><\/svg><\/span>Set-AzContext<\/span> <\/span>-<\/span>Subscription <\/span>"<\/span>xxxx-xxxx-xxxx-xxxx<\/span>"<\/span><\/span><\/code><\/pre><\/div>\n\n\n\nNow you want to list out all the disks you have access to. You want to know their name, location, state and size maybe?<\/p>\n\n\n\n
PowerShell<\/span><\/path><\/path><\/svg><\/span>Get-AzDisk<\/span> <\/span>|<\/span> ft Name<\/span>,<\/span> ResourceGroupName<\/span>,<\/span> DiskSizeGB<\/span>,<\/span> Location<\/span>,<\/span> DiskState<\/span><\/span><\/code><\/pre><\/div>\n\n\n\nThis gives you a list over disks with their names, Resource Group, their physical location, sizes and even what state it’s in. You cannot download a attached disk (with state attached), so you would need to stop that corresponding VM before you can download.<\/p>\n\n\n\n
To list out all VMs, their Resource Group and their state:<\/p>\n\n\n\n
PowerShell<\/span><\/path><\/path><\/svg><\/span>Get-Azvm<\/span> <\/span>-<\/span>Status <\/span>|<\/span> ft name<\/span>,<\/span> ResourceGroupName<\/span>,<\/span> PowerState<\/span><\/span><\/code><\/pre><\/div>\n\n\n\nTo get all disks of a VM, run this:<\/p>\n\n\n\n
PowerShell<\/span><\/path><\/path><\/svg><\/span>Get-Azvm<\/span> <\/span>-<\/span>ResourceGroupName <\/span>"<\/span>resourceGroup<\/span>"<\/span> <\/span>-<\/span>Name <\/span>"<\/span>vm-name<\/span>
