What do you see in $GRID_HOME/log/`hostname -s`/alert`hostname -s`.log ?

What happens if you do 'crsctl start crs'?  What other info do you see in that 
log file after attempting that command?

When you say "a disk was added and files copied", are you saying they added a 
disk, mounted a new f/s, and copied stuff over to new mount point?  It should 
be relatively straightforward to grow a filesystem live.  I know our admins do 
it all the time.

Subject: Newbie Oracle RAC issue

Had a successful first install of Oracle RAC 11gR2 on RHEL6 in the lab... but 
we were running out of disk on the root drive, where Oracle software is 
installed. In my absence, disk was added, and files copied while the 
cluster/database was running. Subsequently one node crashed and is not 
recoverable. The remaining node keeps throwing this error when I attempt to 
start the clusterware:

$  crsctl start cluster
CRS-4639: Could not contact Oracle High Availability Services
CRS-4000: Command Start failed, or completed with errors.

I'm unable to start the clusterware. I looked at the log file, and saw 
references to failures reaching the crashed node, so I thought maybe I have to 
tell the clusterware that we're missing a node, but all the commands I've found 
to do so require cluster services to be running.

What else should I be looking at to diagnose this? I'm trying to evaluate if I 
have to reiinstall everything from scratch or if this lab setup can be 
salvaged. Thanks!

also, please note the following is the only cluster-related process I find  
running on the remaining node:
root      1557     1  0 11:50 ?        00:00:00 /bin/sh /etc/init.d/init.ohasd 
run
