NFS Mount fails using UDP protocol on Fedora 12
Last modified: 2010-12-03 18:03:22 EST
Description of problem:
Fedora 12 mount command will not mount an NFS share using the UDP protocol on an NFS server that has multiple network interfaces
Looks like a possible regression of bug 212471
Version-Release number of selected component (if applicable):
100% of the time on Fedora 12 machines using the UDP protocol
Steps to Reproduce:
1. Create an NFS share on a Linux machine (I used a Fedora 12 server)
2. From Fedora 12 client machine, mount the share using
mount -o udp <server>:/test /test
mount.nfs: mount to NFS server '<server>:/test' failed: timed out, giving up
Mount completes and share is accessible
I tested this problem using a Fedora 8 client, and a Fedora 11 client. Neither of those clients have a problem mounting the same share from the same server. Also, there is no problem from a FC12 client using the TCP protocol :
mount -o tcp <server>:/test /test
there also is no problem from a FC12 client using the UDP protocol with the primary address of the server. For example, the server has two network interfaces (physical or virtual, tested with both), if I use the IP address of the primary interface (eth0 for example) the mount works. If the ip address of eth1 or virtual eth0:0 is used, the mount fails are described above.
The UDP protocol is ideal for setting up a highly available NFS cluster, and the ability for fast recovery times.
Possible regression of bug 212471
I was not able to reproduce this error with the
latest nfs-utils release:
Please download the new version to see it it solves this problem.
This message is a reminder that Fedora 12 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 12. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '12'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 12's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 12 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
