Re: Problem with sem_get() in utils.php

Re: VCL and xCat
Hi
There seems to be a disconnect between xCAT2.pm and
/install/postscripts/partimageng script. The partimageng script starts
listener.py in background which suppose to report to nodestat in xCAT2.pm
module. xCAT2.pm is using 'nodestat nodename stat' to check on status, but
nodestat command doesn't use listener.py running on the node.
Is there a workaround? May be an updated version of xCAT2.pm which checks
/var/log/messages on round2?
Looks like partimageng is using logger to report back the status to xCat
master...
B/c of this, reservation or reload is inconsistent. nodestat would report
install imagename for about 7-9 sec and xCAT2.pm doesn't always get it.
Thank you for your help.

Re: Linux servers with VLAN ID
Hi All
Please ignore this question.
I fixed it with adding a boot script to Linux bare-metal image (in /etc/init.d)
to replace eth1 with eth1. in /etc/rc.local file using sed.
Thanks.

Hi All,
In case if I need to use VLANs on external interface on Linux servers, what
would be the good way to handle eth1.xx interfaces?
I'm adding xCAT support for VCL and xCAT servers have external interface with
VLAD id.
The VCL script in rc.local checks for eth1, but not for eth1.xxx (which is
understandable).
I plan to change 1st two lines to:
IP0=$(ifconfig | grep inet addr:|awk '{print $2}' | awk -F: '{print
$2}'|awk '{ if (NR==1) print $0 }')
IP1=$(ifconfig | grep inet addr:|awk '{print $2}' | awk -F: '{print
$2}'|awk '{ if (NR==2) print $0 }')
or to:
IF0=$(ip -f inet addr|grep inet |grep eth0| awk {'print $7'})
IF1=$(ip -f inet addr|grep inet |grep eth1| awk {'print $7'})
IP0=$(ifconfig $IF0 | grep inet | awk '{print $2}' | awk -F: '{print $2}')
IP1=$(ifconfig $IF1 | grep inet | awk '{print $2}' | awk -F: '{print $2}')
and wanted to ask if anyone had to solve similar problem in the past and may
be have different solution.
I cannot hardcode eth1.VLANID, b/c the same VCL is used for VMs as well, and
those don't have VLANs (VLANs done by ESXi host)
This is original script, which I plan to change:
# This file will get overwritten during image capture. Any customizations
# should be put into /etc/init.d/vcl_post_reserve or /etc/init.d/vcl_post_load
# Note these files do not exist by default.

IP1=$(ifconfig eth1 | grep inet | awk '{print $2}' | awk -F: '{print $2}')

Re: Creating a base image
I have previously added each of the servers and clients into each others Know hosts to eliminate any problems there. I have discovered that I am able to use SSH key authentication between the Management node and the client, but not from the client back to the Management node. Password authentication will work for the SSH connection between the client and management node, but not key authentication. I have tried to copy the management node's private key, which I am assuming is /etc/vcl/vcl.key, to the client machine but to no avail. The client machine still prompts for a password when entering ssh Aaron On 2/28/2012 1:40 PM, Alexander Patterson wrote: Hello Aaron Can you log in into your Vsphere Client ESXI 4.1 Server the one hosting the images Go to Configurations Under Software Click on Security Profile Click on Properties Under Remote Access make sure you have Remote Teach Support SSH is Running and Automatically Turned on You should check if you can ssh without a password from the base image to the management node but also and vice versa.

Dmitri,
At some point, this did work. I'm not sure when it broke, but I never dug
back in to it to make it work again. We've not noticed it causing failures;
so, I just let it go. I can have a look at it again when I get a chance.
Can you send some more detailed information about the conditions when you see
the problem?
One other thing to look at - what does nodestat report after install
imagename? If it is reporting that ssh is running, you may have a
postscript set to configure ssh that is getting run for the stateless image.
We have things set up so that ssh does not get set up for the stateless image.

Is there a workaround? May be an updated version of xCAT2.pm which checks

Re: Creating a base image
It sounds like the issue is related to the communication between the management node and the VMware host. That, at least, is what the attached logs reflect. It is also unclear whether you are trying to access the VM Host via the vSphere API or via SSH. If it is the former, make sure that the vSphere perl modules have been installed and that the vmprofile is properly set up. If it is the latter, make sure that the ssh port is open on the VM host (there are instructions for how to do this here: https://cwiki.apache.org/confluence/display/VCL/VMware+Configuration ) and that the mgmt node is able to login successfully via ssh. As for ssh key authentication between the mgmt node and VMs, I would recommend using the gen-node-key.sh script described at the bottom of this page: https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=4589006 -- Aaron Coburn Systems Administrator and Programmer Academic Technology Services, Amherst College (413) 542-5451 acob...@amherst.edu On Feb 28, 2012, at 3:45 PM, Josh Thompson wrote: You don't want to be able to ssh from the image to the management node - in fact that's a bad idea because it would allow anyone making a reservation for the image to ssh to your management node.

Re: VCL and xCat
Josh
I didn't think that making any major changes to xCAT2.pm would be a good idea.
In fact the solution provided at
https://cwiki.apache.org/VCL/adding-support-for-partimage-and-partimage-ng-to-xcat-2x-unofficial.html
is good and tested. I assume that in newer xCAT nodestat behaves differently.
To get it working again I've created new /opt/xcat/bin/vcl_nodestat script,
which communicates with socket created by listener.py.
#!/usr/bin/perl -w
use strict;
my ($remote, $answer, $peerAddress, $peerPort, $sendCommand);
$peerAddress = $ARGV[0];
$peerPort = 3001;
$sendCommand = $ARGV[1];
use IO::Socket;
$remote=IO::Socket::INET-new(Proto='tcp',PeerAddr = $peerAddress,PeerPort =
$peerPort,Type =SOCK_STREAM) or die $peerAddress: noping\n;
print $remote $sendCommand\n;
while ($answer=$remote){
print $peerAddress:$answer\n;
}
close $remote;
Then I made some minor changes to xCAT2.pm, replacing '$XCAT_ROOT/bin/nodestat'
with '$XCAT_ROOT/bin/vcl_nodestat'.
This seems to fixed the problem.
Thanks.

Re: VCL and xCat
Aaron You mentioned using xCAT to provision end-use desktops at ncsu. How do you handle xCAT r* commands? Did you have to add a remote management card to each desktop to support rpower, etc? Thanks.

From provisioning end-user desktops and our hypervisors. xCAT very helpful when needed to install a chassis full of blades with esxi. As your installing xCAT You'll want to review https://cwiki.apache.org/VCL/adding-support-for-partimage-and-partimage-ng-to-xcat-2x-unofficial.html We added in VCL support for partimage - which is used to capture the disk images of end-user environments/desktops for windows and linux. When your adding nodes to vcl through the manage computers tool, make sure to choose xCAT 2.x . If your doing windows bare-metal, you'll also need to include sysprep and related mass storage drivers so it can be reloaded successfully. For sysprep review step 8 on this page: https://cwiki.apache.org/confluence/display/VCL/VCL+2.2.1+Management+Node+Installation Hope this info helps, Aaron On Thu, Feb 9, 2012 at 4:03 PM, Dmitri Chebotarov dcheb...@gmu.edu wrote: Amit, Thanks a lot.

Install Path in the Edit management Node will be the path for xCAT(bare metal) image repository. In addition when you configure the Site table in xCAT you will set the installdir to point to the location where you will store your images. We have IBM E Blade Chassis with HS22 blade servers.

Once xCat is working then I can add bare-metal computers - blade with xCat 2.x engine. Does it sound right? How do you tell VCL where to get image files for xCat nodes - is it 'Install Path' setting under Management Nodes - Edit management node information? What kind of hardware do you have for xCat nodes? Are those IBM blade servers or/and PCs? Thanks.

I would recommend getting xCAT to work by itself before using VCL to manage your images and guest OS. This has worked well for us so far. :Amit -Original Message- From: dcheb...@gmu.edu [mailto:dcheb...@gmu.edu] Sent: Thursday, February 09, 2012 3:03 PM To: vcl-user@incubator.apache.org Subject: VCL and xCat Hi All Anyone is using xCat with VCL? I have generic question about xCat and VCL - where do I start? Do I need working xCat environment before I can add it to VCL? Does xCat need dedicated server? Or does it run on the VCL management node? Are there any special hardware requirements for xCat clients? Thank you.
