Problem to mount Linux CD-ROM via NFS

Problem to mount Linux CD-ROM via NFS

Post by Jack Ye » Sat, 18 May 2002 00:57:57

Hi all,
    I have a problem to mount an IDE CD-ROM which exported by a RedHat 7.2
Linux machine.
My configuration on Linux machine is as follows.
Linux: /etc/exports
    /mnt/cdrom        *(ro, no_root_squash, insecure)

after exportfs or restart the nfs daemon on Linux machine, I can mount that
exported filesystem by following command.

mount /cdrom

But the problem I encountered is that I can't use this mounted filesystem
Whenever I use this filesystem for a while, it would hang and didn't
response any more.
But I can use "ls" command to browse the contant of CD-ROM once I mounted
that filesystem on my AIX machine.

Could any one tell me what happen? And how to solve this problem? Thank in

Any help will be appreciated.



1. CD-ROM, mounted via NFS on a remote machine access denied

When I mount the CD-ROM to my directory "/usr/kit" or to any other, I have
no trouble viewing the contents of the CD-ROM on the local machine.

When I mount the "/usr/kit" directory on another SCO Box or even a Win
3.11 client I can do so, as long as the CD-ROM isn't attached to it.
If the CD-ROM isn't mounted to the "/usr/kit" directory, then mounting is
easy and painless.  If the CD-ROM is attached the remote device says
"access denied".

I tried attaching the Win3.11 first then the CD-ROM, no errors, and no
information from the ROM.

I have checked and verifed the "showmount -e" does in fact return:

/usr/kit   (everyone)
/pub/cdrom (everyone)

Are there any better ways to work on the CD-ROM to be seen on the network,
I have tried several other directories and have checked that they to are
in the "/etc/exports" with world access.

This happens on either machine:

OpenServer 5.0.2
OpenServer 5.0.4

They both have NFS and function just great with mounting any
directory, as long as the CD-ROM isn't attached to it.

What did I miss ?
