I have some issues with NFS server. I’m using the NFS server to host the rootfs for an embedded Linux in development. The rootfs is created with buildroot and the easiest way to update the rootfs files is by untaring the resulting image to the NFS shared folder. Now it can happen that tar seemingly stops working and my only resolution so far is to restart the nfs-server which also means the next boot of the embedded linux blocks a minute or two on connecting to the nfs server. How can I pinpoint the cause of not being able to update some files on the NFS share in the first place? Sharing single files between server and client work without isssues
