Subject: Re: [Oscar-users] How to add a network drive to the cluster?
Hi Michael,
Thanks for the reply and useful
guides.
It took me quite a while to realize that I also need to mount
the
network drive on the clients
(http://www.tldp.org/HOWTO/NFS-HOWTO/client.html).
I finally got things
to work. :)
It seems that I need to edit the file
/etc/fstab on the clients if I
want the NFS file systems to
be mounted at
boot time. Can you please help me check if the following
is the correct
procedure
to do so? Thanks a lot.
1. Edit
"/var/lib/systemimager/images/oscarimage/etc/fstab" to include
the network
drives
2. Run "cexec updateclient -server tele -image oscarimage" to update
the
file on the clients
I am a bit worried about this procedure because I
notice that originally
there is no
file fstab in the server's image
directory
(/var/lib/systemimager/images/oscarimage/etc/).
However, I can
find this file in the client nodes. I am curious how the
clients got this
file
setup in the first place. If I edit this file on the server's image
now,
would it be in conflict
with the copy on the clients?
Thanks
in advance for any hint.
Sincerely,
Shiang-Tai
