Re: [opensuse] Co-existing in a dynamic network Howto?



2009/3/1 Marc Chamberlin <marc@xxxxxxxxxxxxxxxxxx>:
Hello -  I could use some advise on how to configure our SuSE systems to
work in a dynamic network. I have several computers running SuSE and use
fstab to do a number of automounts of file systems that exist on other
computers within our network. Trouble is that these other computers may come
and go and I do not have control over the exact configuration of the network
at any given time.

I use fstab to define what I want automounted, so as to be able to run some
scripts that access available remote file systems during boot up. (That is
one reason why I cannot use the KNetworkManager as it is not active until
after boot up has taken place and a second is that these scripts must be ran
during the boot up process so as to set up some other server configurations
automatically and not wait until a user has logged in.)

Trouble is two fold. during boot up, if the automount process finds one
computer that does not exist, it times out and seems to give up on mounting
any of the rest of the computers in the list. I would like to get around
this without having to endure a long timeout for each failed mount attempt
also so that the boot up process can be accomplished in a reasonable amount
of time. And, after bootup, this timeout problem also seems to plague the
SuSE menu (in the kicker bar, i.e. the menus displayed when one clicks on
the SuSE logo) When I click on the SuSE menu launcher, it seems to want to
do an automount of all the file systems defined in the fstab file and this
can result in a horrendously long time out process (for each failed attempt
to automount a remote file system) during which the entire kicker becomes
unresponsive and frozen.

I probably am overlooking some simple configuration setting but so far have
not been able to find a method of getting around these two issues. Any help
and suggestions would be much appreciated! (Am mostly running SuSE 11.1 with
KDE 3.5)

The picture is not quite clear for me....

Also, don't use the term "automounted", just mounted (resources to
mount listed in fstab). Given your "dynamic network", you should use
autofs instead, that way the resources will be mounted only when you
try to access them.

Can you elaborate about what you need to run from the mounted FS at
boot time?, Did you specify the "_netdev" option in that FS entry?.
Would help to understand the big picture, maybe some things can be
done in a different/better way....

Regards,
