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
HPE Ezmeral Data Fabric cluster. Create a text file
/tmp/disks.txt
listing the disks and partitions for use by
HPE Ezmeral 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 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.
