Deploy Diskful Nodes with RAID1 Setup on RedHat
-----------------------------------------------
xCAT provides a partition script `./raid1_rh.sh <https://raw.githubusercontent.com/xcat2/xcat-extensions/master/partition/raid1_rh.sh>`_ which setup RAID1 on 2 disks on Power8 LE server, ``raid1_rh.sh`` is composed of 2 parts:
* the logic to select the disks to setup RAID
* the logic to generate the partition scheme and save it to /tmp/partitionfile in the installer.
xCAT provides a partition script `raid1_rh.sh <https://raw.githubusercontent.com/xcat2/xcat-extensions/master/partition/raid1_rh.sh>`_ which configures RAID1 across 2 disks on RHEL 7.x operating systems.
In most scenarios, the sample partitioning script is sufficient to create a basic RAID1 across two disks and is provided as a sample to build upon.
1. Obtain the partition script: ::
wget https://raw.githubusercontent.com/xcat2/xcat-extensions/master/partition/raid1_rh.sh -O /install/custom/raid1_rh.sh
mkdir -p /install/custom/partition/
wget https://raw.githubusercontent.com/xcat2/xcat-extensions/master/partition/raid1_rh.sh \
-O /install/custom/partition/raid1_rh.sh
2. Associate the partition script to the osimage: ::
chdef -t osimage -o rhels7.3-ppc64le-install-compute partitionfile="s:/install/custom/raid1_rh.sh"
chdef -t osimage -o rhels7.3-ppc64le-install-compute \
partitionfile="s:/install/custom/partition/raid1_rh.sh"
3. Provision the node: ::
rinstall cn1 osimage=rhels7.3-ppc64le-install-compute
After the diskful nodes are up and running, you can check the RAID1 settings with the following commands:
