Unable to read file: Invalid argument

I am working with Matlab 2017b and MDCS 2017b. I have a bigger a script but the relevant part goes down to the following:

clear restoredefaultpath;

addpath(genpath('\\irampdevstorage.file.core.windows.net\fileshare\workflow47515'));

folder = '\\irampdevstorage.file.core.windows.net\fileshare\workflow47515';

configurationFile = [folder, '\DATA_CONTAINER1_0000047382.mat'];

spmd

data = load(configurationFile);

end

I am trying to load the file in a remote worker to use it there. If I create a local pool the workers can load the file with no problem. When I work with a remote pool I get the following error:

Error detected on workers 1 2 3 4 5 6 7 8 9 10 11 12.

Caused by:

Unable to read file '\\irampdevstorage.file.core.windows.net\fileshare\workflow47515\DATA_CONTAINER1_0000047382.mat': Invalid argument.

The path is fine and the network shared drive is mapped to the workers VM, so the file is accesible. Any ideas?

I'm gathering the cluster is running Windows?

Try running the following

spmd
    dir \\irampdevstorage.file.core.windows.net
    dir \\irampdevstorage.file.core.windows.net\fileshare
    dir \\irampdevstorage.file.core.windows.net\fileshare\workflow47515
    dir \\irampdevstorage.file.core.windows.net\fileshare\workflow47515\DATA_CONTAINER1_0000047382.mat
end

Let's see how far you can get through each one.

Yes, the cluster is running on Windows Server 2016. Tried to run the code above. When I do it using the local pool it works fine, when I do it using the remote pool I get:

Lab 1:

'\\irampdevstorage.file.core.windows.net\fileshare' not found.

'\\irampdevstorage.file.core.windows.net\fileshare\workflow47515' not found.

'\\irampdevstorage.file.core.windows.net\fileshare\workflow47515\DATA_CONTAINER1_0000047382.mat' not found.

But the shared drive is indeed mapped and accessible in the VM where the remote workers reside, see screenshot.
