Cannot mount RedHat release 7.3 Valhalla NFS share

Hello all!

Can one attach files? What is the best way to share content from "hosts", "fstab", and "exports" files (and I am sure others that one deems pertinent)? Based upon feedback, I will provide file content as requested in the manner recommended.

I will apologize up front--I am a complete moron when it pertains to Linux. I welcome and appreciate all help, including corrections for proper terminology.

I recently inherited old vision inspection equipment that are Linux based--let's call them "system 1" and "system 2". I had to move this equipment and update equipment hostnames and IP addresses. Now, "system 2" won't automatically mount nfs shares onto "system 1". Prior to the move, mounting NFS shares was not a problem.

The OEM isn't really interested in helping me. From their perspective, these systems are pretty old, and my company hasn't purchased equipment from them recently.

System #1
hostname ea154166, IP

System #2
hostname ea154167, IP

uname -a (system 1)
Linux ea154166 2.4.20 #SMP Fri June 20 13:20:21 PDT 2003 i686 unknown

cat /etc/*-release (system 1)
RedHat Linux release 7.3 (Valhalla)

1. When ea154166 boots, it stalls on "Starting NFS services....."
2. After ea154167 boots, I can type "mount -a" and ea154167 mounts directories from ea154166. Previously, one didn't have to do this manually. As long as one rebooted ea154167 after ea154166 was booted, mounted directories automatically happened.

is there some MUST use or need , as in you are FORCED to use a very OLD and unsupported version of red hat
rh7 was released in 2002
ELEVEN -- 11 -- years ago
it will not support any newer hardware

it is so old it predates most of the current network practicals

The OEM isn't really interested in helping me.
that is because not even red hat supports RH7.3 any longer ,and they have not supported it for a VERY long time

RH7 is also SO old that it is using the Linux 2.4 kernel
the 2.4 series of the kernel is and has been retired
-- there is no longer any support for the 2.4 kernel

the 2.6 is currently the only oldest kernel still supported
with 3.11 the current

think of it as running Windows 98 in a windows 8 world

is this machine on a "local" lan
or is it open to the whole web

Since this is a very specialised system and not the typical desktop computer I can see why OS or its software was not updated. The OP did not mention the specific use of the hardware but any equipment that requires some type of certification would cost significant amount of money if changes were made in the course of trying to keep them current.

If you select the Go Advanced button you can attach files to a post. Since you can mount the NFS shares after boot then it should not be to difficult to find the reason. Look at the output of the dmesg command and look for networking and NFS errors. Also check the logs for NFS errors.
