Hi,

I want to store some file on tmpfs or any memory-based file system for better performance and share it via NFS or any protocal that can be used to mount folder. However, from the NFS faq, NFS doesn't support tmpfs.

Could anyone suggest a solution to achieve this?

I tried it here on my machines and it looks like you need to put "fsid=0" in the export options for the share mounted on tmpfs, at which point it appears to work fine.

I have looked around online to figure out exactly what that option means, and it appears it is an NFS4 thing that sets that particular share as the root of the pseudo-filesystem. So this option might be a problem if you need to have multiple exports, though on my server I was still able to mount one of my other shares while I had the tmpfs share active.

Maybe somebody with more intimate knowledge of NFS could clear this up. I don't know if the option is safe to use in a production environment or not.

Thank MS3FGX for your suggestion. I'd try that out. I'm not sure if it works with NFSv3 since I used only NFSv3.
