Hi Götz If you did a rolling upgrade, RBD clients shouldn't have experienced interrupted IO and therefor IO to NFS exports shouldn't have been affected. However, in the past when using kernel NFS over kernel RBD, I did have some lockups when OSDs went down in the cluster so that's something to watch out for.
