DECwest ODE Help,

Enough people have complained about this (this makes 3 since I put back
the supported odemount in place of our local odemount), that I'd say it's
a bug, or at least a very needed feature.  Either the -bg switch should
cause the mounts to use "&", or the ode install script run during bootup
should background the odemount command.

It may be that there's also a QAR against "mount" here.

Thanks...		-josh

Here's an earlier response to the same problem that may answer your question. 
This really has nothing to do with inr, but has to do with change to odemount. 
See the attached message.

Dick,

Is your system setup as an ode client (it should be a client, not
a server).  Is it setup to do odemounts at bootup?  If you're doing
odemount -all, this mounts about 150 filesystems; you may want to
change this to only mount the trees you really use.

There was a change in odemount recently - when you reboot, if you're
setup to call odemount (grep ODEMOUNT /etc/rc.config), then this odemount
uses the -bg switch.  It used to cause odemount to call mount as follows:
	mount filesystem directory &
	mount filesystem directory &
	...
It now does
	mount -o bg filesystem directory
	mount -o bg filesystem directory
	...

Where the 'bg' switch, from the 'man mount' reference page is defined as:

  bg  Retries in the background, if the first mount attempt fails.


If this is hanging your system (some nfs exports may be unavailable),
then this may be a bug in the version of UNIX you're running.  You may
want to file a QAR against Digital UNIX (not ODE).

Try this as a workaround:  modify the file /sbin/init.d/ode3.0 to call
odemount in the background, and to log its output.
I.e., at line 80 of this startup script, change the command from:
  /usr/sde/${ODE_DEFAULT_DIR}/tools/common/odemount ${ODEMOUNT3_OPTS}
  ${ODE_ODEMOUNT_STRING} > /dev/null 2>&1

to:
  /usr/sde/${ODE_DEFAULT_DIR}/tools/common/odemount ${ODEMOUNT3_OPTS}
  ${ODE_ODEMOUNT_STRING} > /var/adm/odemount.log 2>&1 &
                           ^-changed to a file and    ^-added the '&'

If this isn't at line 80 you may have an old startup that isn't calling
using the -bg switch.  Rerun '/usr/sde/install/ode install' if this is
the case.

If anything useful shows up in the log file it may help diagnose the problem.
