<PRE>'Twas brillig, and Guillaume Rousse at 01/10/12 21:41 did gyre and gimble:
><i> With NFSv4, the server remaps its actual filesystem (/home, for
</I>><i> instance) in a pseudo-filesystem, which is seen by clients as a root
</I>><i> filesystem (/ here). Consider it as some kind of implicit chroot.
</I>><i>
</I>><i> With earlier implementations, you had to explicitely mark one of the
</I>><i> filesystem as the root one, and make sure every other filesystem was
</I>><i> reachable from it, using bind mount if needed. You've got some more
</I>><i> detailed explanations here:
</I>><i> <A HREF="https://wiki.archlinux.org/index.php/NFS">https://wiki.archlinux.org/index.php/NFS</A>
</I>><i>
</I>><i> According to official NFS wiki, it seems this is no longer needed, and
</I>><i> than the implementation handle it automagically for you:
</I>><i> <A HREF="http://wiki.linux-nfs.org/wiki/index.php/Nfsv4_configuration#Exporting_directories">http://wiki.linux-nfs.org/wiki/index.php/Nfsv4_configuration#Exporting_directories</A>
</I>><i>
</I>><i>
</I>>><i> I removed 'fsid=0', restarted, and all is well. I
</I>>><i> can see all my data!
</I>><i> Well, you'd better check if you're actually using NFSv4, and not a older
</I>><i> version, if you want optimal performances.
</I>
FWIW, I found I needed fsid=0 on my media center's chroot export when
using an NFS root boot (server + client both mga2).
Without fsid=0 root was mapped to 65534 which caused numerous issues
when booting :)
Never did work out the full reasons, so I probably need to read those
specs a bit.
