Re: [xcat-user] Import 'foreign' image

[Song BJ Yang]

Hi,

 

first of all, "<error>Unable to read private ECDSA key from /etc/xcat/hostkeys</error>" is thrown out by `remoteshell`, which is caused by version difference of openssh-server on MN and CN, ECDSA is not supported on some old openssh-server version, it is not a fatal error and won't block anything.

 

 

what is the node status after provision(`lsdef <node> istatus,statustime`)? 

 

from what you mentioned below, the postscripts have already been executed,

"

The file /etc/log/xcat/xcat.log contains the error message:

 

xcatdsklspost: downloaded postscripts successfully

 

  <error>Unable to read private ECDSA key from /etc/xcat/hostkeys</error>

 

(->  after that mypostscript continues to execute the postscripts correctly)"

 

so what do you mean by "the mypostscript can’t connect to console and begin executing the postscripts"? cannot observe the script execution on console?

 

 

another question is, you mentioned: 

"I’ll use a separate node to create stateless images (for rhel7.5). I don’t want to use the imgexport/imgimport functions as I don’t want to execute (rhels6.9) gen/packimage on the production server.", you can still use imgexport/imgimport to share the osimage between "compile node" and management node, do not need to rerun "genimage" and "packimage" after "imgimport", do not quite get your concern on this

Hello all,

 

Sorry if this has been asked and answered already and I overlook some info in the mail archive.

 

I’ll use a separate node to create stateless images (for rhel7.5). I don’t want to use the imgexport/imgimport functions as
I don’t want to execute (rhels6.9) gen/packimage on the production server.

On the ‘compile’ node I added the production servers ssh host keys to the syncfiles and copy them
to /etc/ssh with help of genimage. The osimage instance on the production node is created with help of a stanza. The content
or build articats (rootimg.cpio.gz, kernel initrd*) are rsync-ed to the production node accordingly to the osimage configuration.

 

Anyway, upon executing the postscripts, the mypostscript can’t connect to console and begin executing the postscripts
after the last system action had been performed. The file /etc/log/xcat/xcat.log contains the error message:

 

xcatdsklspost: downloaded postscripts successfully

 

  <error>Unable to read private ECDSA key from /etc/xcat/hostkeys</error>

 

(->  after that mypostscript continues to execute the postscripts correctly)

 

Does anyone know how to configure the build to make mypostscript connect to the console again?

Many thanks in advance.

 

Cheers,

-Frank
