Hi, Andrew:
Thank you very much for the help. Yes, your
explanation really makes sense. I buy it.
But I would like to discuss it a little bit further.
The following message was part of my previous reply to
Wendy. Just paste it here for your convenience.

I've looked at this problem a bit as well. My system is a 4Gb FC SAN with
a bonded GigE DLM dedicated network. Stat'ing 30,000 files in 3 minutes on
GFS isn't unreasonable considering that it must get and release the gfs
locks. In this scenario, you are averaging about 6ms per file stat. When

Not really. Last week I made a copy of the directory
on the local hard disk (ext3). See the test results
for both "ls" and "ls -la" commands:
# time ls -la | wc -l

In my server room, it is very simple :

Hi,
What result do Cluster Suite waits for when execute /etc/init.d/xxx status?
I guess is a value from RETVAL, if so, which one would be OK and Failed?
