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!
