Note that this doesn't mean it won't use any of that "Minimum Free" space. For example, Minimum is set to 4GB. The disk has 5GB remaining, so it can be chosen. You write a 3GB file. Now the disk has 2GB remaining, and won't be chosen again.

Unraid has no way to know how large a file will become when it chooses a disk for it. If a disk has more than Minimum Free (in your case zero), the disk can be chosen, and if the file won't fit you get the error. You should set Minimum Free to larger than the largest file you expect to write to the share. So if you set it to 4GB as suggested, and the disk has less than 4GB remaining when it chooses a disk to write, it will choose another disk.

What about your disabled disk? You must take care of that immediately. Post your diagnostics.

If it works in SAFE mode and not otherwise that suggests a plugin issue. Which plugins were you using? From the command line, what do you get with this? ls -lah /boot/config/plugins/*.plg

I see you did memtest several months ago. Wouldn't hurt to do it again.

Looks good 👍

Post new diagnostics

The config folder on flash contains everything needed to get going just as before from a new install. Since you say you copied that you should be good. Did you do checkdisk on it?

Fixed my post. OK. Now the way you get all your dockers back is with the Previous Apps feature on the Apps page. When you create or edit a container, those settings are stored in a template on flash. The Previous Apps feature will use those templates to create your containers just as you did before. You may have some templates you weren't using anymore but Previous Apps will let you choose which to reinstall. Try that and let us know how it goes.

You will have to recreate your custom docker network. If you were following SpaceInvader video you probably did this at the command line: docker create network proxynet Correction docker network create proxynet

Looks good. Go to Settings - Docker, change docker.img size to 20G, and enable docker. This will recreate docker.img at 20G on cache. You won't have any dockers yet. We will get to that. I'll leave it up to you whether you want to enable VMs now. Did you have any custom docker networks, such as for proxy?

Not sure why you told us this. Restarting the array isn't really necessary and won't get any of the other things taken care of.

Instead of these screenshots and text descriptions, a much more complete and unambiguous way to show us exactly how you have your dockers configured is to post their docker run commands as explained at this very first link in the Docker FAQ:

In order to change the filesystem of a disk, it has to be reformatted. So you would have to get all its data saved somewhere else before you can convert it to xfs.

OK. Let's see what we can do to get your docker / VM configuration off the array. Go to Settings - Docker, disable docker, then delete docker.img from that same page. Leave docker disabled until instructed to enable again. Go to Settings - VM Manager, disable VMs. Leave VMs disabled until instructed to enable again. Go to your User Shares and set appdata, domains, and system shares to Use cache: Prefer. Go to Main - Array Operation and click Move. Wait for it to complete. May take a while if you have a lot of appdata on the array. Then post new diagnostics so we can see how that all turned out.

Unfortunately, the diagnostics from that old version of Unraid you are using doesn't give us any information about what user shares actually exist. You seem to have over 1000 .cfg files (a record as far as I have seen) in config/shares on the flash drive, many with anonymized names that seem unlikely. I suspect at some point (or possibly different ones at different times) you accidentally created a lot of user shares. Any folder at the top level of cache or array is automatically a user share. The reason I bring this up is because it can make it difficult to give advice regarding your user shares since it looks like you have so many. Open up that diagnostics you posted and you will see what I mean. How many user shares do you actually have?

Hey "Advanced Member"😉 The other things I mentioned are not technically errors, just less than ideal configuration of your dockers and VMs. Do you actually have any VMs?

This thread you have posted to is nearly 8 years old and is in the Legacy Support (unRAID 5 and Older) subforum. Start a new thread in General Support and post your Diagnostics.

Good luck! Maybe those videos linked above will help you ask better questions.

What do you want the VMs to connect to? We seem to be going around in circles here. Each VM is a (virtual) computer. A VM can connect to the internet, it can connect to other machines on your network, including other VMs on the server. A faster connection is just that, a faster connection. There is no specific speed requirement for the network in order for you to have VMs. It would even be possible to setup a VM and then never use that VM to network with anything. I don't really understand why you are asking about this. I assume you have some experience with home networks and obviously you can access the internet. The VMs are just computers that would use your network in the same way any other computer would use your network.

The VMs themselves don't need internet to work with the video cards, etc. They only need internet the same way any computer needs internet. Your questions make me wonder how much you will have to learn to even get started on this though. Have you ever built a PC?

Not that much of a bullet to bite if you do it correctly. For future reference. Go to Settings - Docker, disable dockers, then you can delete docker.img on that same page. Then on that same page, you can edit its path and enable docker to recreate it at the new path. Then the Previous Apps feature on the Apps page will add your dockers back exactly as they were. Since your templates (mappings, etc) are on flash, and the working storage (appdata) of the applications are in the user share, Previous Apps together with these will download your dockers executable code (the only thing missing, which is what winds up in docker.img) and set them up exactly as before.

Assuming the hardware is well chosen and works well, there is still a bit more that needs to be setup on the software side of it to actually make this happen. Unraid isn't really a multi-user operating system, but it can host VMs (Virtual Machines), which are like separate computers. These VMs can have their own monitor, keyboard, etc.

You connect Unraid by ethernet to your router, and other computers on that router's network can access the Unraid server by ethernet or wifi. Maybe I am still missing something because what I have just described is pretty basic home networking.
