Hi, Jeff
Thanks for the reply, here is the information:
1. Yeah, I ran the test on the same node I start lamboot from.
2. Yeah, /lamtests-6.5.9 is NFS mounted on to all nodes, it's exactly the
same path on all nodes, including the nodes it exported from.
3. /lamtests-6.5.9/reporting/collector exists on the node I ran the test
from, have the permission 750.
4. I can't manually run the collector, I even change the mode to 755,
still no luck.
Really confusing me!
Thanks very much for your time!
Best
Yu
