On the Primary Storage page, check the information of all
primary storages, including names of primary storages, storage types, URLs,
capacities of primary storages, states, and statuses. In addition, you can add,
enable, and disable one or more primary storages.
Primary Storage Operations
You can perform the following operations on a primary storage:
Search: Support three types of search method on the primary storage page:
name, UUID, and advanced.
Add a primary storage: Add a primary storage to the cloud. Each primary
storage has its own corresponding primary storage type. When you select
different primary storage types, the Add Primary Storage page is a
bit different. This chapter will introduce all these differences according
to the types.
Enable: Enable the primary storage that is in the disabled state. Batch
operations are supported.
Disable: Disable the primary storage. After you disable the primary storage,
you cannot create new VM instances, volumes, and snapshots by using the
primary storage. Original resources are not affected. Batch operations
are supported.
Reconnect: Reconnect the primary storage. When you reconnect the primary
storage, the storage information that is associated with the primary storage
will be updated. Batch operations are supported.
Note: If any one of
hosts can connect normally to the primary storage, the status of the
primary storage will be Connected.
Create volume: Create a volume on the primary storage. Then, this volume
will be an instantiated volume. Only a single operation is
supported.
Note: Shared volumes currently support two types of
primary storage: Ceph and Shared Block.
Attach cluster: Attach the primary storage to the specified cluster. One
cluster can attach multiple storages.
The following are primary storages of
the same type that a cluster can have:
A cluster can have one or more LocalStorage
primary storages attached.
A cluster can have one or more NFS primary
storages attached.
A cluster can have one or more Shared Block
primary storages attached.
A cluster can have one Shared Mount Point
primary storages attached.
A cluster can have only one Ceph primary storage
attached.
The following are
combinations of primary storages that a cluster can
have:
A cluster can have both a LocalStorage and an
NFS primary storage attached.
A cluster can have both a LocalStorage and a
Shared Mount Point primary storage attached.
A cluster can have both a LocalStorage and a
Shared Block primary storage attached.
A cluster can have both a Ceph and a Shared
Block primary storage attached.
A cluster can have both a Ceph and more than one
Shared Block primary storage attached.
Detach cluster: Detach the primary storage from the specified
cluster.
Note: If you detach a primary storage from a cluster, note
that:
All VM instances on the primary storage will be stopped.
All vRouters or VPC vRouters on the primary storage will be
deleted. In this regard, the network services of related VM
instances will be abnormal.
All volumes on the primary storage cannot be used normally.
Enter maintenance mode: After the primary storage enters the maintenance
mode, all VM instances (including NeverStop) that use the primary storage
will be stopped. Batch operations are supported.
Delete: Delete the primary storage. Batch operations are supported.
Note:
Before you perform this deleting operation, verify that you
detach the primary storage from all clusters.
Deleting the primary storage is a very dangerous operation. If
you perform this operation, all resources on the primary storage
will be deleted, such as VM instances, volumes, and snapshots.
Even if you add this primary storage again, the original files
cannot be automatically detected.
Clean up: Clean up original data (trashes) reserved during the migrations
across Ceph primary storages, the migrations across NFS primary storages,
and the migrations across Shared Block primary storages. On the
Clear Data tab, click Clean
UP to clean up trashes reserved during the storage
migrations. Exercise caution. After you clean up the trashes successfully,
the trashes cannot be recovered.
Note: If any one of
hosts can connect normally to the primary storage, the status of the
primary storage will be Connected.
