Images based on CentOS 7.3

These images are based on the default image from Bright Cluster Manager.

Clone the default image to “new” name

 [bright1->softwareimage]% clone default-image compute-image
 [bright1->softwareimage]% clone default-image login-image
 [bright1->softwareimage]% clone default-image sched-image

Clone the default category to a “new” category

 [bright1->category]% clone default compute
 [bright1->category]% clone default login
 [bright1->category]% clone default scheduler

Set the default software image for each category

 [bright1->category*[compute*]]% set softwareimage compute-image
 [bright1->category*[login*]]% set softwareimage login-image
 [bright1->category*[scheduler*]]% set softwareimage sched-image
 [bright1->category*]% commit

Images based on CentOS 6.7

* Install CentOS 6.7 manually on a physical machine [hostname “iml”]

* Copy ssh-keys from Bright server to the physical machine

 [root@bright1 ~]# ssh-copy-id root@172.18.0.187
 [root@bright1 ~]# ssh root@172.18.0.187 
 Last login: Sun Aug 13 18:47:05 2017 from master.cm.cluster 
 [root@iml ~]#

* Copy CentOS 6 repo for Bright manager and dell repository

 [root@bright1 general_repos]# scp cm.repo 172.18.0.187:/etc/yum.repos.d/cm.repo
 [root@bright1 general_repos]# scp dell-osma-repository.repo 172.18.0.187:/etc/yum.repos.d/dell-osma-repository.repo

* Install additional packages for dependencies on the physical machine

 [root@iml ~]# yum groupinstall -y "development tools" [gives me rsync, perl etc]
 [root@iml ~]# yum install redhat-lsb-core  [cmd init script requires it]
 [root@iml ~]# yum install smartmontools  ["smart" healthcheck fails without it]

* Create image from the physical machine

 [root@bright1 images]# cm-create-image --fromhost 172.18.0.187 --imagename iml-image --hwvendor dell
