Determine if a disk or partition is ready for use by HPE Ezmeral Data Fabric
Explains the procedure to determine whether a disk or partition is ready for use by HPE Ezmeral Data Fabric.
About this task
Any disk or partition that passes the following testing procedure can be added to the
list of disks and partitions passed to the disksetup
command.
- Run the command
sudo lsof <partition>
to determine whether any processes are already using the disk or partition.There should be no output when running
sudo fuser <partition>
, indicating there is no process accessing the specific disk or partition. - The disk or partition should not be mounted, as checked via the output of the
mount
command. If the disk or partition is mounted, unmount it using theumount
command. - The disk or partition should not have an entry in the
/etc/fstab file
; comment out or delete any such entries. - The disk or partition should be accessible to standard Linux tools such as
mkfs
. You should be able to successfully format the partition using a command likesudo mkfs.ext3 <partition>
as this is similar to the operations that HPE Ezmeral Data Fabric performs during installation. Ifmkfs
fails to access and format the partition, then it is highly likely that HPE Ezmeral Data Fabric will encounter the same problem.
