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
```

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
```
