This section describes how to format disks for cluster storage manually by using
disksetup.
The disksetup utility formats
disks for use by the data-fabric
cluster. disksetup removes all data from the specified disks. Make sure
you specify the disks correctly, and back up any data that you want to save. If you are
re-using a node that was used previously in another cluster, it is important to format the
disks to remove all data from the old cluster. For more information about the utility, see
disksetup.
disksetup script assumes that you have free, unmounted physical
partitions or hard disks for use by data-fabric software. To determine if a disk or partition is ready for use by data-fabric software, see Setting Up Disks for MapR. If data-at-rest-encryption (DARE) is enabled, you must use a different set of steps for
configuring storage using disksetup. See the appropriate subtopic in this
section.
