Evaluate HPE Ezmeral Data Fabric using a flat storage file instead of formatting disks
For evaluation, you can use a flat storage file instead of formatting disks.
About this task
When setting up a small cluster for evaluation purposes, if a particular node does
not have physical disks or partitions available to dedicate to the cluster, you can
use a flat file on an existing disk partition as the node's storage. Create at least
a 16GB file, and include a path to the file in the disk list file for the
disksetup script.
The following example creates a 20 GB flat file (
bs=1G specifies 1
gigabyte blocks, multiplied by count=20) at
/root/storagefile:dd if=/dev/zero of=/root/storagefile bs=1G count=20Add the created flat file to the disk list file
/tmp/disks.txt to be
used by disksetup:/root/storagefile
