Hello list, Since I set up IPv6 on my LAN, I've been unable to NFS-export a directory on machine A (an Atom serving portage via git, among other things) and mount it on machine B (this workstation). It was working fine until then, but now mount commands fail. In both kernels I have NFSv4 selected, but not 4.x; no fancy extras like ACLs.
I went back to the Gentoo nfs-utils wiki page and made sure I had everything right, then searched for other people's problems. Nothing has helped so far. On the server: $ cat /etc/conf.d/nfs NFS_NEEDED_SERVICES="rpc.idmapd" OPTS_RPC_NFSD="1 -N 2 -N 3 -V 4 -N 4.1" OPTS_RPC_MOUNTD="-p 32767" OPTS_RPC_STATD="-p 32765 -o 32766" OPTS_RPC_IDMAPD="" OPTS_RPC_GSSD="" OPTS_RPC_SVCGSSD="" OPTS_RPC_RQUOTAD="" EXPORTFS_TIMEOUT=30 $ cat /etc/exports mnt/nfs 192.168.1.5/24(rw,no_subtree_check,crossmnt,fsid=0) \ fe80::5/64(rw,sync,no_subtree_check,crossmnt,fsid=0) /mnt/nfs/portage 192.168.1.5/24(rw,no_subtree_check,anonuid=250,anongid=250,fsid=1) \ fe80::5/64(rw,no_subtree_check,anonuid=250,anongid=250,fsid=1) /mnt/nfs/port.resc 192.168.1.5/24(rw,no_subtree_check,anonuid=250,anongid=250,fsid=2) \ fe80::5/64(rw,no_subtree_check,anonuid=250,anongid=250,fsid=2) $ grep nfs /etc/fstab /usr/portage /mnt/nfs/portage none bind 0 0 On the client: $ grep nfs /etc/fstab 192.168.1.2:/mnt/nfs/portage /mnt/atom/usr/portage nfs4 noauto,rw,_netdev 0 0 Now I try to mount /usr/portage from the host on /mnt/atom/usr/portage (which does exist) and get this: # mount /mnt/atom/usr/portage mount.nfs4: mounting 192.168.1.2:/mnt/nfs/portage failed, reason given by server: No such file or directory # mount 192.168.1.2:/mnt/nfs/portage /mnt/atom/usr/portage mount.nfs: mounting 192.168.1.2:/mnt/nfs/portage failed, reason given by server: No such file or directory # mount [fe80::2]:/mnt/nfs/portage /mnt/atom/usr/portage mount.nfs: mount system call failed It doesn't seem to be a firewall problem, because I get the same result if I start both machines without their firewalls - I don't do that very often! Ping works fine in both directions, whether IPv4 or v6. Do I have to tweak mapd somehow? I'm feeling a bit clueless... -- Regards, Peter.
