Hi, I want to use this option, but i find it doesn't work at RHEL5.4GA and Fedora12. My /etc/exports like this: # cat /etc/exports /nfsroot/nfsv4 127.0.0.1(rw,nohide,fsid=0) /nfsroot/nfsv4/dir1 127.0.0.1(rw,nohide,crossmnt) /nfsroot/nfsv4/dir2 127.0.0.1(rw,nohide,crossmnt) Then: # mkdir /nfsroot/nfsv4/dir1/tmpdir # echo "best wishes" > /nfsroot/nfsv4/dir1/file1 # echo "happy new year" > /nfsroot/nfsv4/dir2/file2 # service nfs restart # mount -t nfs4 127.0.0.1:/dir2 /nfsroot/nfsv4/dir1/tmpdir # mount -t nfs4 127.0.0.1:/dir1 /mnt There is file2 at /nfsroot/nfsv4/dir1/tmpdir, but nothing at /mnt/tmpdir. I'm not sure i have used it correctly, and whether it really work? Thanks for your help. -- Best Regards Bian -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
