Even you server was upgraded, I pretty sure that the FAI nfsroot was not rebuilt. The read-only issue is often caused by a NFS v4 issue. You can fix that by forcing NFS v3 for the nfsroot. I do this by adding nfsver=3 to the pxelinux.cfg file for the install client. The whole option then looks like this: root=1.2.3.4:/srv/fai/nfsroot,nfsvers=3 Also make sure you are using the option rootovl if you are using a 4.x kernel which enables overlayfs. In the past we used the option aufs, but this is only for 3.x kernels. -- regards Thomas
