Hi Nathan,
 
Thanks Russ.
We cannot configure gateway in nics table. You can configure gateway in networks table for the specific networks , confignetwork also use the gateway from networks table, but confignetworks
If you want to configure the default gateway as the static gateway, after running confignetworks , you can use makeroutes or setroute script to do that , here is my draft doc for these 2 command/script https://github.com/xcat2/xcat-core/pull/4580/commits/e9fd1c9e345997e409b54229be159bafadc3de73

The gateway field should be used to set the default route. Make sure there's just one gateway set if you use multiple nics, otherwise the last one will win.

We had similar issue (after postscripts, reboot hung) on x86 system, change
bootmode to "Legacy only" fixed.

I will try to ask my teammate to look into this also.  and you can follow
this issue on github.

The host was with Boot Mode of "UEFI and Legacy". I performed the steps you
advised me but it didn't work, same outcome as before.

As a side note, I did the steps you said on a physical node. We also manage
vms (running on VMware ESXi) with that xCAT. Their state is the same as
with nodes - we run nodeset and reboot - and they get stuck on the same
step as the physical nodes. Everything works for them as well when we
enable xcatdebugmode. So the boot mode might not be the issue.

What do you think?
Thanks

Subject: Re: [xcat-user] Debugmode solves stateful installation
hang after postscripts



In addition to Daniel's response, I would like to add more
information. I work with Daniel and his mail is related to me as
well, of course.

While debugging the issue, we added a lot of debug messages to the
postscripts and postbootscripts, in order to determine the exact
step that the installation gets stuck on. These debug messages are
written to a file, which is accessible through SSH (the node is
accessible via SSH while running the postscripts).

While examining the file during the installation, we can see that
it fills up with debug messages. We have a debug message on each
script's beginning and end. The last debug message is the ending of
the latest script of "postscripts". Since the node does not reboot,
we don't reach the postbootscripts at all.

In addition to that, by examining the output of "lsdef  -i
currchain" during the hang, we get "boot". When trying to forcibly
reboot the node, it just boots up as expected, runs the
postbootscripts and finishes. It seems that the node does
acknowledge its state to xCAT, but it does not reboot.

As Daniel stated in his previous mail, turning on "xcatdebugmode"
on the "site" table causes the whole process to work.

We would like to understand what is causing this problem.

Thanks

[xcat-user] How to inject updates to osimages for stateless nodes?

2018-01-09 Thread Kevin Keane

Generally speaking, osimages are created with the copycds command from an
ISO image.

This will, of course, create an image that is based on the snapshot when
the OS first came out.

With the Meltdown and Spectre vulnerabilities, I would like to update my
image with all the latest packages. We are currently using RH 6.7, and I
want to update it to RH 6.9 plus all the latest updates.

What is the recommended method to do that?

Thanks!

Hello,

I have encountered a strange issue where sending any node to rinstall "hangs"

Trying to diagnose the issue led to the strange bit.

Setting xcatdebugmode=1 in site table SOLVED the issue while still not showing 
any error in any log.

We have verified this is indeed the case - setting it to 0 reverts to non 
functioning rinstall, re-setting to 1 and rinstall works without an issue.

We would like to work without debugmode - what might be the issue and how can 
we solve this?

xCAT version - 2.13.8

xCAT node OS - RHEL 7.4

Nodes OS - RHEL 6.5
