Finally I came back to my beowulf cifs issue and, as actually expected, it was easily solvable at the client. From beowulf mount.cifs(8) for the "SMB protocol version" option: The default since v4.13.5 is for the client and server to negotiate the highest possible version greater than or equal to 2.1. In kernels prior to v4.13, the default was 1.0. For kernels between v4.13 and v4.13.5 the default is 3.0. The upgrade was from kernel v4.9 to v4.19; forcing the former default version 1.0 (vers=1.0) on mount made the shares writable again. Staying with the new default SMB version 3.0 (I /thought/ that I had tried this before), mount.cifs requires the "noperm" option to pass on the write permissions. lessons: 1.
