[Bug 836533] Re: Still problems with nfs-mounts in /etc/fstab on boot
The remote 0/0 speaks of issues and I see later changes in mountall.c that could address reliability of startups. 415 Even if the mounting/mounted event failed (due perhaps to a failure of a job depending on it), we still want to proceed with the mount and not just error out. 411 Make sure we reset the pending_call to NULL when handling the event, so that we correctly rehandle after a failed mount attempt. http://bazaar.launchpad.net/~ubuntu- branches/ubuntu/raring/mountall/raring/changes I neglected to save output of mountall --verbose and I neglected to try connecting to the system over ssh in lucid where I saw no further upstart activity on the console after about 3 failed NFS mount attempts. ** Changed in: mountall (Ubuntu) Status: Expired = Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/836533 Title: Still problems with nfs-mounts in /etc/fstab on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mountall/+bug/836533/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I had the same bug, and found the problem: Running IPv6 first and IPv4 afterwards (in /etc/networking/interfaces) did not work.

[Bug 836533] Re: Still problems with nfs-mounts in /etc/fstab on boot
(Most likely the problem is related to DHCP assigned network interfaces not being up when mountall expects them to. This will cause a time out condition that is only resolved after a considerable amount of time and sometimes not at all, I.e the NFS shares remain unmounted when the user logs in.) Mountall makes no assumptions about network interfaces being up; on the contrary, the network bring-up scripts signal mountall to re-try all network mounts. This works reliably for me, and I have three NFS entries in my /etc/fstab that mount without problems at boot. Do you know if this bug still exists in 12.04? I suspect it's been fixed in later releases. If you can still reproduce it in 12.04, please attach your /etc/network/interfaces file and /etc/fstab. Please also edit /etc/init/mountall.conf to comment out the 'console output' line and add a '--verbose' option to the mountall exec line. ** Changed in: mountall (Ubuntu) Status: Confirmed = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/836533 Title: Still problems with nfs-mounts in /etc/fstab on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mountall/+bug/836533/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 836533] Re: Still problems with nfs-mounts in /etc/fstab on boot
The nfs-upstart-fixer, as posted by Hans Höök --- A FIX for the problem = We have also noticed that for some hosts, more often with multiple cpu cores in our experience, NFS shares are not mounted in time during upstart. We have tried NFS v3 and v4 with Ubuntu 8.04 servers and Ubuntu 10.04 clients. If /home is an NFS share this will cause a lot of trouble since a login without a home catalog will result in a locked up gnome session that requires sudo rights and some command line skills to resolve. (Not the kind of situation you would like your users to find themselves in...) It is a shame that this problem still persists – we have suffered from its consequences since 10.04 was released and not been able to find its root cause. To help others in the same condition we have decided to publish our fix – even thought it is quite ugly it works and removes the symptoms. (Most likely the problem is related to DHCP assigned network interfaces not being up when mountall expects them to. This will cause a time out condition that is only resolved after a considerable amount of time and sometimes not at all, I.e the NFS shares remain unmounted when the user logs in.) The following fix will provide peace of mind and happy users: 1. In /etc/fstab make sure all NFS mounts have the flag “noauto” set like: 10.0.0.250:/home /home nfs4 noauto 0 0 2. Add the attached upstart script /etc/init/nfs-upstart-fixer. If you use NFS v4, that uses idmapd, uncomment: 'start on (net-device-up and started idmapd) ' If you use NFS v3, that does not depend on idmapd, uncomment: 'start on (net-device-up) ' 3. Add the attached script /sbin/ensure-nfsshares-mounted. 4. Above will take care of most situations but if you are using gdm and are quick when logging in there is still a chance that the home share may not be mounted. To be sure add the following line to the script /etc/gdm/PostLogin/Default: /sbin/ensure-nfsshares-mounted This will act as a guard. (Read instructions in /etc/gdm/PostLogin/Default.sample if ther is no /etc/gdm/PostLogin/Default in your system.) Note 1: The “magic” time constant of 8 seconds /etc/init/nfs-upstart-fixer is empiric. It works on all hosts I have seen this far. If it is too small there will be a time out condition which will cause the time between entering password and until the login is completed by quite a long time. If this happens try with 10, 12, 14 until this does not happen. Note 2: For non gdm users there is probably a “hook” corresponding to /etc/gdm/PostLogin/Default. Note 3. If you have NFS shares in /etc/fstab that are truly intended to be “noauto” the above solution will have to be modified a bit. Hope you may now also enjoy swift boot up and NFS mounted home shares in Ubuntu even though this embarrassing bug remains unfixed!
