Red Hat Bugzilla – Bug 3867
knfsd does not allow non-linux machines to mount exports.
Last modified: 2008-05-01 11:37:51 EDT
I recently upgraded from 5.0 -> 6.0. Before the upgrade I
had /home exported to a number of SunOS5.6,Digital Unix 4.0,
and IRIX 6.2,6.5 machines. I could have my home directory
autmount without any problems before the upgrade. After
the upgrade I couldn't even do an automount. I tried
all of the flags I could including vers=2 and nothing
seemed to work.
I removed the knfs rpm's and installed the following two
rpm's from the 5.2 package.
This immediately fixed my problem. I then thought it might
be a problem in upgrading from RedHat5.0 -> 6.0 so I
reformatted the harddrive and did a fresh install. I still
could not mount the exported linux filesystems on any
platform but linux.
I don't know what is different about the knfsd package but
something is missing.
Please let me know how to fix this.
knfsd advertises but does not support NFSv3. There is some obscure
bug that prevents automatic fall back to NFSv2. Meanwhile, the
workaround is to not advertise NFSv3 at all. Add the flag in the
appropriate place in /etc/rc.d/init.d/nfs to look like
echo -n "Starting NFS mountd: "
daemon rpc.mountd --no-nfs-version 3
You might also want to look at the knfsd package at rawhide.redhat.com
which includes this fix and possibly others.
