8 months ago @alessio1983lx Sounds like you're talking about using having Talos Linux use CONFIG_NFSD option in the kernel. I suspect that this won't get added as an official feature. One could say that having and running NFS server in the kernel would be a security concern. You could compile your own kernel with the option turned on and I then suspect OpenEBS NFS Dyanmic Provisioner would work without issue.. However, my suggestion would be to look at using perhaps Longhorn RWX (NFS Server) volumes which make use of userspace level NFS (Ganesha). Longhorn has recently gained support for Talos Linux as of version 1.6 and it runs great in my experience.

Compatibility with Open EBS NFS Dynamic Provider

Hello, i can't get Open EBS NFS Dynamic Provider to work, after the pvc is provisioned the container which provides the nfs server to attach fails his job

It cannot mount nfsd to /proc/fs/nfsd , i think because nfs modules are missing in Talos Kernel... is there a way to work around or load that modules? Is it possible to add these nfs server functions in future releases?
