Notes to use xCAT-genesis-base-x86_64
1. before install it, you shall remove the xcat-genesis-scripts-x86_64/amd64 and old xcat-genesis-base-x86_64/amd64_2.13.2. Then, install xcat-genesis-base-x86_64/amd64_2.13.9 package above and reinstall xcat-genesis-scripts-x86_64/amd64. 2. pls run `mknb x86_64` after install.

goconserver to provide remote access to system consoles
-
the goconserver daemon v0.1.0 for accessing system consoles is available at https://github.com/chenglch/goconserver/releases
-
integrate with xcat interface rcons, makegocons
Technical Preview for goconserver(Beta) feature
If you would like to try goconserver(beta) - the new lightweight console server of xCAT, follow the steps below:- Stop and disable conserver service on MN and all service nodes
systemctl stop conserver systemctl disable conserver
- Download the latest goconserver package and install it on MN and all service nodes
wget https://github.com/chenglch/goconserver/files/1558246/goconserver-0.1.0-snap201712140221.ppc64le.rpm.tar.gz tar xvfz goconserver-0.1.0-snap201712140221.ppc64le.rpm.tar.gz yum install goconserver-0.1.0-snap201712140221.ppc64le.rpm
And you could add this package into otherpkgs list of the osimage for service node.
- Define your compute node with as normal, and using makegocons to register compute nodes into goconserver. Then you could use rcons to access the console.
# chdef cn01 conserver=sn01 # makegocons cn01 cn01: Created # rcons cn01
- Unregister the console for compute nodes
makegocons -d cn01
Known Issue:
- Failed to start goconserver on service node, You could copy the certificate files to serivce node for a workaround.
xdcp service /etc/xcat/cert/* /etc/xcat/cert/ makegocons cn01
- Failed to register compute node into goconserver.
If you start
goconserver
service before you runningmakegocons
, /etc/goconserver/server.conf may not be generated successfully. You can workaround it with below steps:
systemctl stop goconserver makegocons cn01
- conserver is started on service node when restarting xcatd (node reboot, xCAT upgrade, etc), and it will cause duplicate console session for compute nodes. Just to stop conserver manually.
systemctl stop conserver
Note: To switch back to conserver, just follow below steps:
makegocons -d systemctl stop goconserver systemctl start conserver systemctl enable conserver makeconservercf
