Comment 21 for bug 656889

I just discovered that I have the same problem here. This computer is supposed
to mount two fileservers. One of the fileservers runs Centos 5 and the other
is an Intel SS-4000E (a dedicated fileserver that runs its own embedded Linux).

The Centos 5 fileserver server mounted fine, just like it did before, but the Intel fileserver failed.

My fstab is set up as follows:

fileserver:/nas/NASDisk-00002/files/ /mnt/fileserver nfs
defaults 0 0

After rebooting my computer last night when it finished updating to
nfs-utils-1.2.0-5.fc11.x86_64 the fileserver failed to mount. I found out
about it this morning when my overnight backup to the fileserver failed to work.

Running the mount command from the commandline tells me this:

QUOTE:
[root@mutt frankcox]# mount fileserver:/nas/NASDisk-00002/files/ /mnt/fileserver

mount.nfs: requested NFS version or transport protocol is not supported
END OF QUOTE:

Using the suggested option "-o proto=udp", it mounted fine.

QUOTE:
[root@mutt frankcox]# mount -o proto=udp fileserver:/nas/NASDisk-00002/files/ /mnt/fileserver
END OF QUOTE

That worked and my Intel fileserver is now present on this computer again.
