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 <node> -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

I can ssh to the node, but when trying to ssh back from the node to the
xcat server it requires a password.
ssh_keys is set to postbootscripts. Should I move it to postscripts?

Ensure that the node can ssh back to the MN in the anaconda

Hello,
I have encountered a strange issue where sending any node to
rinstall "hangs" after finishing the postscripts - it never
reboots, and therefore never continue to the postbootscripts.
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
Thanks,
Daniel Letai
