Disk Size

DiskSize defines the virtual size of a volume. Virtual size is the size that a volume claims for. In other word, the virtual size is the maximum size that a volume can occupy in storage system after it is fully filled.

State

Allocator Strategy

1. The state is Enabled.
2. The status is Connected.
3. The available capacity (availableCapacity) is greater than the disk size (diskSize) of the disk offering.
4. The primary storage is attached to the cluster that runs the VM instance to which the volume will be attached.

Parameters

Note:

• When you create a disk offering in ZStack Cloud, you can customize the disk offering parameters by adding the diskOfferingUserConfig option to SystemTags.
  • Format of the diskOfferingUserConfig option: diskOfferingUserConfig::xxx. Here, xxx must be a JSON string.
    For example, to specify multiple primary storage for a disk offering, you can use diskOfferingUserConfig::

    {
        "allocate": {
            "primaryStorages":[
                {
                    "type":"Enter a primary storage type",
                    "uuid":"Enter a primary storage UUID"
                },
                {
                    "type":"Enter a primary storage type",
                    "uuid":"Enter a primary storage UUID"
                },
                {
                    "type":"Enter a primary storage type",
                    "uuid":"Enter a primary storage UUID"
                }
            ]
        }
    
    }

Parameters

System Tags

Dedicated Primary Storage

When you create a volume from disk offering, you can use a system tag to specify the primary storage on which the volume will be created.

primaryStorage::allocator::uuid::{uuid} > primaryStorage::allocator::userTag::{tag}::required > \
primaryStorage::allocator::userTag::{tag}
