• After all required partitions have been created, exit parted using the quit command.
If a partition was added, removed, or changed while both nodes are powered on and con-
nected to the shared storage, reboot the other node for it to recognize the modifications.
After partitioning a disk, format the partition for use in the cluster. For example, create
the file systems for shared partitions. Refer to Section 2.5.3.2 Creating File Systems for
more information on configuring file systems.
For basic information on partitioning hard disks at installation time, refer to the Red Hat
Enterprise Linux Installation Guide.
2.5.3.2. Creating File Systems
Use the mkfs command to create an ext3 file system. For example:
mke2fs -j -b 4096 /dev/sde3
For optimal performance of shared file systems, make sure to specify a 4 KB block size
with the mke2fs -b command. A smaller block size can cause long fsck times.
