Various situations lead to a volume being in a reserved state. If you are deleting a volume and has associated snapshots, you need to delete them first, before deleting the volume. Additional personal project quota requests will not be accepted.īadRequest: Failed to delete volume with name or ID: Invalid volume: Volume status must be available or error or error_restoring or error_extending or error_managing and must not be migrating, attached, belong to a group, have snapshots or be disassociated from snapshots after volume transfer. Please contact the helpdesk to request to raise this limit for a project. VolumeLimitExceeded: Maximum number of volumes allowed (N) exceeded Additional personal project quota requests will not be accepted. Please note that additional quota is only granted for shared projects. If you require further quota, please contact the helpdesk. Your total space for the volume service exceeds the allowance for the project. VolumeSizeExceedsAvailableQuota: Requested volume or snapshot exceeds allowed Gigabytes quota.ERROR: openstack Request Entity Too Large (HTTP 413) Retyping will silently fail if the volume is still attached or if the retyping is not possible. Once the volume has been created, it can be attached to the virtual machine. This status can be checked using $ openstack volume show. The status reported will become available when the volume has been created. +-+-+ | Field | Value | +-+-+ | attachments | | | availability_zone | nova | | bootable | false | | consistencygroup_id | None | | created_at | T12:43:22.000000 | | description | Volume for documentation | | encrypted | False | | id | bb17fd17-9c52-4a62-9e85-42fff55f80d6 | | multiattach | False | | name | testvol | | properties | | | replication_status | None | | size | 100 | | snapshot_id | None | | source_volid | None | | status | creating | | type | CEPH_1 | | updated_at | None | | user_id | b1580497f51e4d10b9110c60c154562c | +-+-+ $ openstack volume create -description "Volume for documentation" -size 100 testvol The following types are currently available: Volume typeĭescribes the type of storage that is being requested. This is useful if you need more space than is provided on the initial flavor and can also allow some interesting flexiblity for snapshotting or moving volumes around between virtual machines. You can define additional volumes to be attached to a virtual machine in addition to the system disk. Volumes are stored on redundant storage and are therefore more resilient against hardware failures. not like a distributed filesystem), but they may be detached or reattached to a different instance while retaining all data, much like a USB drive. Volumes can be attached to a single instance at a time (i.e. Volumes are persistent virtualized block devices independent of any particular instance. The service level for ephemeral storage is dependent on the underlying hardware. The size of the Ephemeral storage is defined in the flavor of the virtual machine and is fixed for all virtual machines of that particular flavor. Ephemeral storage exists only for the life of an instance, it will persist across reboots of the guest operating system but when the instance is deleted so is the associated storage. OpenStack provides two classes of block storage, ephemeral storage and persistent volumes. Volumes (create/delete/snapshot/extend.)
