Specify disks or partitions for use by HPE Ezmeral 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 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 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.
