This topic describes how to add a Shared Block primary storage in the ZStack Private Cloud UI.
Add Shared Block Primary Storage
In the navigation pane of the ZStack Private
Cloud UI, choose Hardware > Primary Storage. On the Primary Storage page, click
Add Primary Storage. On the displayed Add
Primary Storage page, set the following parameters:
Zone: By default, the current zone is displayed.
Name: Enter a name for the primary storage.
Description: Optional. Enter a description for the
primary storage.
Type: Select SharedBlock.
Thick Provision/Thin Provision: Select the
provisioning method, including thick provision and thin provision.
Thick provision: Allocate the required storage space in advance to
provide sufficient storage capacities and to ensure storage
performances.
Thin provision: Allocate storage spaces as needed to achieve a
higher storage utilization.
Storage Network: Indicate the storage network
specified for the shared storage. The storage network can be shared by the
management network of the management node.
Note:
If you have an independent storage network, you need to enter
the CIDR of the storage network.
You can use this storage network to check the health status of a
VM instance.
Cluster: Select a cluster to mount the primary
storage.
Shared Block: Select a Shared Block. You need to
enter WWIDs. You can add multiple LUN devices.
Note: Make sure that compute
nodes can normally connect to storage devices, and have been added to
the cloud.
Clear SharedBlock: Choose whether to clear LUN
devices. This checkbox is not selected by default.
If selected, the residual data in LUN devices will be forced to
clean, including file systems, RAID, or signatures of partition
tables.
If your LUN devices store data, and you do not clean the devices,
you will fail to add LUN devices or attach primary storages.
When you add LUN devices, the devices must not include partitions.
Or otherwise, you will fail to add the devices.
