Hi:
I am installing lustre 1.5.95 on a small sun x4200 cluster running
FC5 kernel version 2.6.15. I had some difficulty getting kernel
patched and rpms compiled, but by reading discussion i was able to
get over those problems. The problem now is i am testing the simplest
scenario and it failes. I put mgs and mdt on node 1, called gg202.
OST on the second node, called gg203. Then client on the third node,
called gg204. All the mkfs and mount on these three nodes seems fine,
and /proc/fs/lustre/devices seems ok as well. But after i mount the
client at gg204 when try to copy sth to the mounted directory on
gg204, the gg202 node, i.e., the mgs and mdt node, stops responding.
I have to manually power it down. I can not find any useful
information at gg201's system log, and gg202 and gg203's system log
simply says connection lost. So now i am really confused. Thanks for
the patience.
