Specify disks or partitions for use by HPE Data Fabric

Describes the use of the disksetup script to format disks.

About this task

The disksetup script is used to format disks for use by the HPE Data Fabric cluster. Create a text file /tmp/disks.txt listing the disks and partitions for use by HPE Data Fabric on the node. Each line lists either a single disk or all applicable partitions on a single disk. When listing multiple partitions on a line, separate by spaces. For example:

/dev/sdb
/dev/sdc1 /dev/sdc2 /dev/sdc4
/dev/sdd
Later, when you run the disksetup script to format the disks, specify the disks.txt file. For example:
/opt/mapr/server/disksetup -F /tmp/disks.txt
NOTE
The disksetup script removes all data from the specified disks. Make sure you specify the disks correctly, and that any data you wish to keep has been backed up elsewhere.
If you are re-using a node that was used previously in another cluster, be sure to format the disks to remove any traces of data from the old cluster.
NOTE
Run the disksetup script only after running the configure.sh script.
