After the OS deployment for the compute node, you should see the file /etc/xcat/hostkeys/ssh_host_dsa_key on compute node. Could you compare this file with the one on the Management Node? They should be same.
Thanks
Best Regards

Hi,
> Please show output of 'lsxcatd -a'.
# lsxcatd -a
Version 2.11.1 (git commit b6e4c8ca1847bf574d7e86687d74a7f2576d428a,
built Thu Apr 14 09:32:27 EDT 2016)
This is a Management Node
dbengine=SQLite
> Is there any error/warning message when running the remoteshell postscript?
Not on the console of the compute node, only in the logfile on the
management node with site.xcatdebugmode=1 enabled.
> Could you ssh to the compute node when the system is running Postscript.
Yes, the login to the compute node is possible when Anaconda starts
installing RPMs.
During that time in /etc/ssh/ I can only see a "ssh_host_rsa_key" and no
"ssh_host_dsa_key".
> As a workaround, you can move the postscript syncfiles to

I will give it a try. Thanks for the hint.
