If I start rpcgssd.service, the mounts are instantaneous. A lot of people are hit by this problem, see: https://bbs.archlinux.org/viewtopic.php?pid=1312879 https://ask.fedoraproject.org/question/30612/nfs-gss-problems-on-f19/ http://joshuawise.com/kerberos-nfs https://wiki.archlinux.org/index.php/NFS#Client (or just google for that error message) Reply at: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1277741/comments/3 ------------------------------------------------------------------------ On 2013-11-12T13:40:10+00:00 Jeff wrote: Upstream patch posting: http://article.gmane.org/gmane.linux.nfs/59939 Reply at: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1277741/comments/4 ------------------------------------------------------------------------ On 2013-11-15T13:29:56+00:00 Jeff wrote: Revised upstream patch posting here: http://article.gmane.org/gmane.linux.nfs/60081 Reply at: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1277741/comments/5 ------------------------------------------------------------------------ On 2014-01-06T15:06:03+00:00 Jeff wrote: Backported versions of these patches have been merged into f19 and f20 kernels, so this should no longer be a problem there.

Reply at: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1277741/comments/6 ** Changed in: fedora Status: Unknown => Fix Released ** Changed in: fedora Importance: Unknown => Undecided -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1277741 Title: 15 sec timeout when mounting with nfs4 Status in linux package in Ubuntu: Fix Released Status in Fedora: Fix Released Bug description: With the default nfs-common configuration (rpc.gssd not running), there is a 15 second delay when mounting an NFSv4 filesystem. After setting NEED_GSSD=yes and starting rpc.gssd, there is no delay. I don't know exactly when this was introduced. I reproduced it in trusty, in saucy, and in precise with the lts-saucy kernel, but not in raring. The patch series fixing this was merged recently and will be in 3.14: http://article.gmane.org/gmane.linux.nfs/60081 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4b9a445e3eeb8bd9278b1ae51c1b3a651e370cd6 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=89f842435c630f8426f414e6030bc2ffea0d6f81 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6aa23d76a7b549521a03b63b6d5b7880ea87eab7 Not part of the original series, but there are a few fixes on top of those: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=3396f92f8be606ea485b0a82d4e7749a448b013b https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=e2f0c83a9de331d9352185ca3642616c13127539 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=23e66ba97127ff3b064d4c6c5138aa34eafc492f Fedora and openSUSE have backported the fix to their 3.11-based kernels: http://pkgs.fedoraproject.org/cgit/kernel.git/commit/?h=f19&id=6142d53dbe77431a4cc54f7ec80413b06f4ab182 http://pkgs.fedoraproject.org/cgit/kernel.git/commit/?h=f20&id=a585abfb8457a34cf6a5e737aa5fd75dbfe2559b http://kernel.opensuse.org/cgit/kernel/commit/?h=openSUSE-13.1&id=b2c797e218e1b2694f3e5d2d470bed6fb1b82009 http://kernel.opensuse.org/cgit/kernel/commit/?h=openSUSE-13.1&id=b876acdd9ab5a5a81f7690ad0fc2f54ee83ac642 http://kernel.opensuse.org/cgit/kernel/commit/?h=openSUSE-13.1&id=b4901f2cf60e02895336b8bde254c0eef07c09dd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1277741/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
