RE: [BProc] Newbie questions

One other point is I have 1GB RAM on my master versus 256MB on all my slave
nodes. Could that cause any problems? Do I need to set some ulimits (-m) on
the slave? 

Another oddity is that when I strace bpsh or node_up, I do not see any
special "bproc" system calls getting executed like SYSCALL(....), though I
should have executed them per the code path. Insights?
 
Thanks.

Subject: RE: [BProc] Newbie questions

Hi folks,

I went ahead and installed ClusterMatic 4 over a clean RedHat 9.0 on the
master of my 5-node Intel P4-based cluster. The beoboot part works fine to
bring the slave nodes up and running connected to port 2223 of master, but
the node_up script seems to fail at the end, so node gets marked as "error"
state. What could the reasons be? Any help will be appreciated.

ON MASTER (node_up script fails):
$# tail -15 /var/log/clustermatic/node.0
vmadlib   :     loaded /lib/ld-2.3.2.so
(size=103044;id=0,0;mode=100755)

nodeup    : Finished creating child processes.
nodeup    : I/O error talking to child
nodeup    : Child process for node 0 died with signal

nodeup    : Node setup returned status 1


ON SLAVE (things look fine):
boot: Server IP Address	: 10.0.0.1
boot: My IP Address	: 10.0.0.100
boot: starting bpslave : bpslave -d -i -v 10.0.0.1
2223
bpslave: connecting to 10.0.0.1:2223
bpslave: IO Daemon started; pid 15
bpslave connection to 10.0.0.1:2223 up and running
bpslave: Setting node number to 0


Now, if I force the master to mark status of slave node to be "up", bpsh
fails like this. I tried "vmadlib -l" and it does show /lib/ld-2.3.2.so, but
execing slave cannot seem to find it. I also looked at the strace of (strace
-f) bpmaster, and one odd thing is it tries to close a whole host of socket
descriptors (4096 instances) that are not open. Please
- any help will be appreciated.
ON MASTER:
$# bpctl -S 0 -s up
$# bpstat
Node(s)                            Status         
Mode       User     Group

---------- root     root
0                                  up             
---x------ root     root

$# bpsh 0 sleep 1
0: No such file or directory

ON SLAVE:
 vmadump: mmap failed: /lib/ld-2.3.2-so


Thanks.
