on the site table, turn on the "xcatdebugmode"
chdef -t site xcatdebugmode=1
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,
Casandra Qiu

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

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,
