[Bug 1384502] Re: fstab entry for nfs /home fails to mount on boot

 

Confirmed.  The issue here is that as an NFS mount not mounted under
/usr or /var, mountall implicitly treats this as 'nobootwait'.  It's
debatable whether this should be done, but the other issue is that
filesystems being marked 'nobootwait' doesn't just prevent them from
blocking the boot, it also prevents them from being waited for at all -
if they become available while mountall is running it will mount them,
but otherwise mountall will exit without caring that there are still
filesystems that could possibly come online later and need mounted.

This is definitely a bug in mountall.

Title:
  fstab entry for nfs /home fails to mount on boot

Status in “mountall” package in Ubuntu:
  Triaged

Bug description:
  i'm uncertain exactly when this issue started as we use cfengine
  (verifies all expected mounts in place, manually mounts those that are
  not).  from a note i have i believe it goes back as far as lucid.

  the symptom is that an /etc/fstab entry for an nfs-mounted /home is
  not mounted during the system boot. once the system is network-
  accessible, manually running `mount -tnfs -av` as root (or using
  cfengine or any number of other solutions) is sufficient.

  per lp#836533 i added "--verbose" to /etc/init/mountall.conf and will attach the resulting /var/log/upstart/mountall.log and /etc/network/interfaces. the smoking gun appears to be:
  mount.nfs: Failed to resolve server nfs-home: Temporary failure in name resolution
