I have a situation where I have multiple Windows servers on the same LAN. Each server has multiple folders containing ISO files. I want to mount all of those remote folders, containing the ISO's, to a single directory on a particular Linux server. I'm trying to have a single directory on this particular Linux server that contains all of the ISO's, from all of the other servers. Is this even possible?

I have tried using fstab with the following code but it does not work:

However, it works if I comment out either of the lines so that there is only one folder being mounted to that Linux directory.

There are a few ways to join directories/filesystems together but not sure how well it will work with remote filesystems. I would try overlayfs.

Assuming you are using a systemd based distribution you could write a service to overlay after the network is up and the shares are mounted.

Thank you for your question, it gave me something to think about.

Perhaps overlayfs will suit your needs, but if it does not, how about this idea?

- a script that mounts each remote share to a separate subdirectory, then reads the directory of the share it just mounted, and adds each iso file as a symlink in one single master directory. Anyone looking at that master directory would see all the iso files.

Of course you would need to deal with file names duplicated across shares. And to update added/removed iso files.
