Well I just stopped Docker and changed the Docker data-root to vDisk and am having to reinstall all of the CA apps AGAIN! haha

I also had to recreate my custom network as it was missing...

User Shares are simply the combined top level folders on array and pools.

When you create a User Share in the webUI, Unraid creates top level folder(s) on array and/or pools as needed, in conformance with the settings you make for the share.

Conversely, any top level folder on array or pools is automatically part of a User Share named for the folder. If you don't make settings for a user share, it has default settings. All your user shares have default settings.

I think that I mostly understand this...

I see in your log you created 20G docker-xfs.img

But when you took the diagnostics you had disabled Docker so I didn't get a chance to see how full that 20G was. Don't know how many of your containers you had reinstalled yet.

appdata and system are on cache and configured to be only on cache. That is good.

All others are configured to not use cache, but

b----p                            shareUseCache="no"      # Share exists on disk1, cache

Configured to not use cache, but files already exist on cache. They won't be moved because Mover action can't be set, because Secondary storage isn't set.

Important to set Minimum Free for each of your user shares, and for cache.

Here is the new diagnostics with Docker running:

I know that in the documentation that it states that the docker-xfs.img file be set to between 20-40gb but doesn't state what the min on the shares should be set to. Is there an easy way to calculate this and put it into the Shares config?

You are using 12G of the 20G. If you have installed all your containers 20G is going to be plenty. If usage ever starts to grow even though you haven't installed additional containers, that means you have some application writing to a path that isn't mapped.

The docs do discuss this, but the short answer is, set it to larger than the largest file you expect to write to the user share.

You must also set Minimum Free for cache to larger than the largest file you expect to write to cache.

So based on what you're saying and the fact that I am using this mostly as a media share, i.e. Plex and Immich, I would want to set the minimums to:

media +/-15gb

data +/- 5gb

iso's +/- 10gb

photo_immich +/- 3gb

cache +/- 15gb

Does this sound correct?

The largest files that I will be migrating will be in the neighborhood of 10gb being movies, everything else will be smallish.

Is there a way to restore the all of the VM's that I had previously installed without going back through and doing them individually, having to set them all up from scratch?

It should be if you have a backup of libvirt.img, that's where all the VM XMLs are stored.

Would I just replace the newly created .img file with the backup? Then reinstall the VM's? I am unfamiliar with this process and I looked over the Unraid documentation as it does reference restoring VM's but I could not find the steps to do so... Any assistance would be appreciated!

Thank you!

Assuming you still have the vdisks for each VM (in domains usually), you shouldn't have to reinstall anything. libvirt.img just lets Unraid manage them.

I tried replacing the libvirt.img file with the file that was the backup and couldn't figure out how to get it working so I chalked it up to a loss and am in the process of re-installing them... Oh well... Thank you so much for your help and walking me through the issues I was having.

Thank you!
