updatenode will issue command from management node and process command

postscripts on the compute node /xcatpost/ will be downloaded again from

-V options will show more debug information, hopefully we can see why
failed to downloaded the postscripts.
by the way, after you rebooted the node, did u see any error message
from /var/log/xcat/xcat.log?

I have never used updatenode. Just reboot. Would that help debug?

Did u try to run "updatenode" again for the current compute node? add
verbose "-V" to the option, should able to get more logs.
Thanks,

Thanks, it’s good to know I’ve got a hundred or so copies with
changes back to 9/2017 on our compute nodes.
However even after restoring postscripts/hostkeys, postscripts/_xcat
and postscripts/_ssh and checking the
files we created are still there, the diskless boot still fails:
Mon Jul 2 10:27:35 EDT 2018 [info]: xcat.xcatdsklspost: trying to
download postscripts...
Mon Jul 2 10:28:14 EDT 2018 [err]: xcat.xcatdsklspost: failed to
download the postscripts from the xCAT server for node
node552.oscar.ccv.brown.edu
I will try restoring all the changed scripts, but would like to know
at what point it decided it was a failure.
All the /xcatboot files seem to be there. I tried prepopulating
the /etc/ssh directory in the image, but that didn’t help.
Where do I turn up the debugging?
Thanks!

hi David Johnson,
In the scenario you described, I think xCAT installation
will affect the stuff under `/install/postscripts`
1) files with the same name with the files under
`/install/postscripts` shipped by xCAT will be
overwritten
2) the credentials under "/install/postscripts/hostkeys",
"/install/postscripts/_xcat" and
"/install/postscripts/_ssh/" and
"/install/postscripts/ca/" will be overwritten
You can restore the original "/install/postscritps"
directory with the "/xcatpost" directory on the compute
nodes(non-hierarchy cluster) or service nodes(hierarchy
cluster) which are not provisioned after xCAT
reinstallation with `go-xcat` accidentally.
good luck

Hi Dave,
Thanks for reporting this, can you open a issue here?
https://github.com/xcat2/xcat-core/issues
If it's inconvenient, please let me know and I'll open
one on your behalf.
Thanks,

I’m trying to set up a separate cluster with a new xcat
master node, and downloaded and ran the go-xcat script.
I realized afterwards that it had updated a whole bunch
of files in /install, which I had forgotten was
nfs-mounted
from our main cluster’s master node.
Right off the bat, I’m thinking there might be a problem
with ssh keys, and ca.pem.
Any other likely trouble spots? I put all our netboot
stuff in /install/custom, and we
have added postinstall scripts rather than customizing
ones from the distribution.
I can probably go out to any of the nodes still running
and grab individual files back.
Thanks,
�D ddj
