This is a bug introduced in nodestat. I am getting the same results with nodestat, nodestat -h nodestat -v. Please open a defect in tracker. Lissa K. Valletta 414/3-8 Poughkeepsie, NY 12601 (tie 293) 433-3102 "Enke, Morgan \(A&E\)" <Mor...@ml...> Sent by: xca...@li... 05/28/2009 06:44 PM Please respond to xCAT Users Mailing list <xca...@li...> To <xca...@li...> cc Subject [xcat-user] nodestat not returning expected results I?ve recently installed xCAT 2.2.1 (xCAT-server-2.2.1-snap200905151316) on a RHEL 5.2 x86_64 server. So far so good ? I have 3 nodes setup, successfully provisioned one with a stateless RHEL image, expected results from ?tabdump site?, nodels, lsdef <node>, etc. However, I?m having a couple of problems with nodestat. The first problem is that I?m receiving the following error when just entering ?nodestat? (no noderange)- # nodestat Error: nodestat plugin bug, pid 26664, process description: 'xCATd SSL: nodestat for root@localhost: nodestat instance' with error 'Can't use an undefined value as an ARRAY reference at /opt/xcat/lib/perl/xCAT_plugin/nodestat.pm line 174. ' I compared the nodestat.pm with the same file from a previous snap (xCAT-server-2.2.1-snap200904291731) and there was one difference- [root@bwyhs00540p bin]# diff /opt/xcat/lib/perl/xCAT_plugin/nodestat.pm /tmp/nodestat.pm 78d77 < return [$req]; #For now, do not distribute, nodestat seems to lose accuracy and slow down distributed I commented out that line and the problem went away. The second problem is that the output of nodestat is incorrect. I started with one node (pingable, sshd running) and nodestat didn?t return anything ? not even a ?noping? ? it just returned to a prompt. I then added a couple other nodes and nodestat continued to skip the first host, but returned results for the 2nd and 3rd hosts. However, the 2nd and 3rd hosts were returning ?noping? even though they were pingable. Lastly, I shutdown the first host, and nodestat then reported with a status ? correctly returning a ?noping?. # nodestat compute n01: noping n02: noping n03: noping In all cases, I verified the hostnames were resolvable and also verified via tcpdump that the xCAT server was sending out the icmp,ssh,pbs, etc. packets and receiving responses (except in the last case where I shut the host down of course). Any ideas? Thanks.
