Provision a New Disk
To provision new disks, first turn off you DME (either physically or shutdown a VM). Add
the disk accordingly. After restarting your DME you should see the new disk in the
New Disks
Found
table with a button to "
Provision
". Provisioning is the act of formatting (for xfs file
system) and adding the new disk storage to the DME common data storage location. In other
words, this extends the existing files system over the new disk and the new disk may not be
removed once provisioned.
It is also important to note that for VM installs Vbrick only supports the expansion of the
disk space by creating additional virtual disks and provisioning them using the
Maintenance
>
Disk Status
page. While VM hosts may allow the expansion of virtual disks, they do not
automatically expand the disk partitions within the VM OS. Meaning, the DME does not
detect that expansion of the partition on the virtual disk. The solution in this case is to add
an additional new virtual disk.

Tip : When extending space with Virtual Disks, Vbrick recommends creating
additional virtual disks and provisioning them using the Maintenance > Disk
Status page. While VM hosts allow the expansion of already provisioned virtual
disks, they do not automatically expand the OS disk partitions contained within.
Meaning, the DME does not detect that expansion of the partition on the
virtual disk so the added space will not be detected. Alternatively, iSCSI disks
can also be added to VMs – please see SAN/iSCSI Setup.
