7.2.1 Copying files to the cloner
Copy the RHEL 6 installation tree to the cloner, along with the other files associated with this
book, by performing the following steps:
1. Mount the /nfs/rhel6/ directory on the NFS server over the /mnt/ directory. In this
example, the NFS server is at IP address 9.60.18.240:
# mount 9.60.18.240:/nfs/rhel6/dvd1 /mnt
# ls /mnt
boot.cat RELEASE-NOTES-es-ES.html RELEASE-NOTES-pt-BR.html
EULA RELEASE-NOTES-fr-FR.html RELEASE-NOTES-ru-RU.html
...
2. Create a local directory of the same name and recursively copy the tree with the cp -a
command:
# mkdir -p /nfs/rhel6
# cd /mnt
# rsync -av * /nfs/rhel6
sending incremental file list
EULA
GPL
...
sent 2758827676 bytes received 56977 bytes 9180980.54 bytes/sec
total size is 2758270745 speedup is 1.00
This command will take some time, perhaps 5 to 10 minutes, depending on network
speeds.
