We've eliminated most of those. There's only one filesystem that is still used with nullfs (specifically to avoid a large number of otherwise identical mounts). Here are the "nfsstat -m" mount flags for that filesystem: nfsv4,minorversion=3D2,oneopenown,tcp,resvport,nconnect=3D1,hard,cto,nolock= d,sec=3Dsys,acdirmin=3D3,acdirmax=3D60,acregmin=3D5,acregmax=3D60,nametimeo= =3D60,negnametimeo=3D60,rsize=3D65536,wsize=3D65536,readdirsize=3D65536,rea= dahead=3D1,wcommitsize=3D16777216,timeout=3D120,retrans=3D2147483647 The server of this filesystem is 14.1-RELEASE-p5 and the exported filesystem is a readonly ZFS dataset. Thanks!
