Comment 5 Luigi Toscano 2020-05-07 16:00:24 UTC
On the Cinder side, we add some recommendation around the usage of NFS (tl;dr recommendation to avoid the Generic NFS backend; use NFS 4.1), that are now live for OSP13, OSP15 and OSP16 (see https://bugzilla.redhat.com/show_bug.cgi?id=1807992 and the related bugs).
