CentOS 7.4 client mounting a CentOS 7.4 server filesystem over nfs4. nfs seems to be much slower since the upgrade to 7.4, so I thought it might be nice to mount the directory as v4.0 rather than the new default of v4.1 to see if it makes a difference. The release notes state, without an example: "You can retain the original behavior by specifying 0 as the minor version" nfs(5) states: ** Recent kernels allow the minor version to be specified using the vers= option. For example, specifying vers=4.1 is the same as specifying vers=4,minorversion=1. ** but in fstab or on the command line, using either form (vers=4.0 or vers=4,minorversion=0), if I run mount afterwards, I still see vers=4.1 for the mount. I'm missing something obvious, but the only thing obvious to me is that I can't see it. Any help is greatly appreciated. Cheers, Zube
