Update master
To update use:
- Edit files in '/etc/yum.repos.d/' and set enable=1. At least enabled repositories in:
- CentOS-Base.repo
- epel.repo
- rpmforge.repo
- Ensure that in /etc/yum.conf, caching is enabled:
- keepcache=1
- Then update the master node fully using:
- yum -y install --skip-broken
Update compute nodes
To update compute nodes, on master node use:
- After the frontend is fully updated use following to copy all packages from all repositories to be installed on client nodes:
- cd /var/cache/yum/x86_64/7
- cp */packages/*.rpm /export/rocks/install/contrib/7.0/x86_64/RPMS/
- Build a new rocks distribution using:
- cd /export/rocks/install
- rocks create distro
- Reinstall nodes as per CentOS 7.x Rocks cluster 7.0 Reinstall OS on compute node
- During installation if you see errors such as:
- libpsm2-compat-<version> required libpsm2(x86-64) = <version2>
- Then go to /export/rocks/install/contrib/7.0/x86_64/RPMS/ and delete offending files manually
- rm -f libpsm2-*
- Again try reinstalling compute node after executing:
- cd /export/rocks/install
- rocks create distro
