Formatting Disks on a Node From the Command-line
Provides an overview of the disksetup script to format disks from the command line.
The disksetup script is used to format disks for use by the
MapR cluster. Create a text file
/tmp/disks.txt
listing the disks and partitions for use by
MapR 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 disksetup to format the disks, specify
the disks.txt
file. For example:
/opt/mapr/server/disksetup -F /tmp/disks.txt
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.
