Extreme Newbie question

Post by homer0 » 2006/08/13 18:50:30

Hello All,
I am in the middle of a "Trial by Fire" since our network admin took a new job and I am suddenly responsible for a cluster with linux nodes.

The master node runs on win2003 server, when it connects to the nodes it reads a config file on each node:

PVM_ARCH=LINUXI386
PVM_ROOT=/usr/share/pvm3
PVM_RSH=/usr/bin/rsh
PVM_TMP=/tmp
PVM_VERSION=3.4.4

export PVM_ARCH PVM_ROOT PVM_RSH PVM_TMP PVM_VERSION

Everthing was working fine until we had an unexpected power outage. Now instead of looking for RSH in /usr/bin/rsh on some of the nodes it tries to use a different diectory starting with /kerbos/... ( i'm not sure the exact path)


(1) I am assuming that after the power outage the linux nodes reverted to some sort of default configuration? can this be modified?

(2) Is there a global config file that will tell Centos which path I want it to use?

(3) If I delete the other Directory /kerbos/... do you think the linux node will revert to using the original path?

I have not worked much with linux and I did not set up the cluster, any help will be greatly appreciated
