Is a bad NFS mount preventing a clean boot?

  • 772

I'm on Ubuntu server (I think it's 12.04, but not positive) and I basically ran into this problem here Unmount a nfs mount where the nfs server has disappeared

The umount command didn't work, so I tried to just use the ol' reboot. Now the machine gets an error when booting:

FS-Cache:netfs 'nfs' registered for caching
<two minutes later>
init: udevtrigger post-stop process (345) terminated with status 1

I tried booting in recovery mode so I could just comment out the bad NFS mount in my /etc/fstab file, but I wasn't able to write the changes.

I basically just want to get the machine booting properly again so that I can erase the bad mount point, either order is fine.

What are my options here?

  1. You can try to do this in rescue mode:

    mount -o remount,rw /

    and then modify your /etc/fstab.

    Or boot LiveCD and mount / somewhere with "rw".

    I got into recovery mode and ran mount -o remount,rw / which allowed me to get rid of my bad NFS mounts in /etc/fstab (and I prevented further issues by adding the intr option to the NFS entries), but then my boot (in non-recovery) seemingly got worse -- I got no output on the screen after selecting normal boot from the GRUB menu!

    I then added nomodeset to the GRUB_CMDLINE_LINUX_DEFAULT boot option list and everything worked.

    I have no idea how those two were related, but that's what fixed the issue.
