Message-ID: <53418E98.8030505@gmx.de> Date: Sun, 06 Apr 2014 19:27:52 +0200 From: Toralf Förster <toralf.foerster@....de> To: Linux Kernel <linux-kernel@...r.kernel.org> Subject: NFS V4 calls for a NFS v3 mount -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Probably a question better suited for a NFS noobs mailing list (is there any around ?) ... While playing with kernel 3.13.x, wireshark and NFS I realized, that mounting a NFS v3 share results in NFS V4 Calls - is this indented or a wireshark dissector issue ? $ cat /etc/exports # /etc/exports: NFS file systems being exported. See exports(5). /mnt/ramdisk 192.168.0.0/16(rw,fsid=0,insecure,no_subtree_check,async,no_root_squash) $ grep nfsv3 /etc/fstab n22:/mnt/ramdisk /mnt/nfsv3 nfs auto,bg,intr,soft $
