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

Subject: [xcat-user] go-xcat accidentally run with /install mounted from production xcat master

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,
