disktab

Describes the use of the disktab file.

On each node, the file /opt/mapr/conf/disktab lists all of the physical drives and partitions that have been added to the file system. The disktab file is created by the disksetup command, and automatically updated when disks are added or removed (either using the Control System, or with the disk add and disk remove commands).
