I found what's going on, it looks to me like there is another race condition between upstart and systemd scripts, sometimes rc.local gets to mount some of my NFS shares but other times it doesn't. The first thing I tried was doing a loop until ifconfig was showing a valid address but it didn't work either, at the time network card got the IP address the route was not present, so I've done a loop waiting for the route to be ready, and then mount the volumes.
aux=0 while [ $aux -eq 0 ]; do route -n > /tmp/network if grep "192.168.40.1" /tmp/network; then aux=1; fi done echo "mounting home" >> /tmp/network mount /home 2>> /tmp/network echo "mounting data" >> /tmp/network mount /data 2>> /tmp/network echo "mounting usr" >> /tmp/network mount /usr/local 2>> /tmp/network exit 0 And having /etc/fstab not to mount at startup. fourier:/export/data /data nfs vers=3,rsize=32768,wsize=32768,nosuid,soft,noauto 0 0 But this is a very quick and dirty solution, any workaround more gentle? -- 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/1118447 Title: Race condition with network and NFS mounts causes boottime hang Status in “linux” package in Ubuntu: Confirmed Status in “nfs-utils” package in Ubuntu: Incomplete Bug description: I seem to experience a race condition during boot of my ubuntu 12.04 server: In approx. one of seven boots, the server hangs during bootup. This is what I see on the screen: After the line * Starting configure network device there is a short delay of about 1 second, then messages continue. I see * Starting Mount network filesystems [ OK ] * Starting set sysctls from /etc/sysctl.conf [ OK ] * Starting configure network device [ OK ] * Stopping Mount network filesystems [ OK ] * Stopping set sysctls from /etc/sysctl.conf [ OK ] * Starting Block the mounting event for NFS filesytems until statd is running [ OK ] * Stopping Block the mounting event for NFS filesytems until statd is running [ OK ] * Starting Block the mounting event for NFS filesytems until statd is running [ OK ] * Stopping Block the mounting event for NFS filesytems until statd is running [ OK ] The last messages repeats several times, and then the boot process hangs. In 6/7 of cases, I wait for a minute, and after that bootup continues. But in approx 1/7 cases, the system hangs at this point forever. The machine does not respond to CTRL-ALT-DEL, I have to reboot it using SysRq-Keys. WORKAROUND: Setting the NFS entries in fstab to "noauto" completely removes the problem: There is no timeout during boot, and no lockup any more. The machine boote smoothly with the NFS-shares unmounted. After the machine is up, we can manually mount the NFS-shares without a problem.
