G.3 Configuring an Operating System Disk
The first two disks support the Linux operating system. These disks store a copy of the mirrored operating system, a swap partition, a mirrored boot partition, and an HDFS data partition.
To configure an operating system disk, you must copy the partition table from the surviving disk, create an HDFS partition (ext4 file system), and add the software raid partitions and boot partitions for the operating system.
Complete these procedures after replacing the disk in either slot 0 or slot 1.
