  • Fujitsu ETERNUS DX driver: Improve volume deletion

    To improve the volume deletion process, add a step to check associated copy sessions. Additionally, it also improves the process of retrieving storage-managed volume numbers.

    There was a problem where the volume could not be deleted because the copy session information acquired by SMI-S IF from ETERNUS DX Storage, which was cached and did not reflect the information that had just been executed.

    This problem has been addressed through improvements in information retrieval.

  • Fujitsu ETERNUS DX driver: Add fragment capacity information of RAID Group.

    ETERNUS DX driver have two types of storage pools: RAID Group and ThinProvisioning Pool. Volumes can not be created in RAID Groups for the following situations:

    • The maximum sequential physical free space is smaller than the volumes to be created.

    • 128 volumes have already been created in the RAID Group.

    For the above reasons, to monitor the maximum sequential physical free space and total volumes in the RAID Group, when updating pool information using Get Volume Stats, also update parameter total_volumes (volumes already created in the RAID Group) and introduce fragment_capacity_mb (maximum sequential physical capacity) to the backend pool information if the backend pool is a RAID Group.

    Meanwhile, since creating volumes on ThinProvisioning Pool does not encounter the above restrictions, parameter fragment_capacity_mb will not be added into the information, and remove the total_volumes parameter from the backend pool information when the type of backend pool is ThinProvisioning Pool.

    These two parameters can be utilized in future implementations of functions related to filter_function.

    This patch also enabled the multiattach in the driver information.

  • Pure Storage FlashArray drivers upgraded to remove REST 1.x support and changed to REST 2.4 as the minimum supported version.

  • Pure Storage FlashArray drivers changed minimum supported Purity//FA version to 6.1.0.

  • StorPool driver: improved the way volumes are cloned into different StorPool templates (exposed as Cinder storage pools) if requested, eliminating some data duplication in the underlying StorPool cluster.

  • StorPool driver: implemented revert to snapshot, which happens immediately i.e. without deleting and recreating the volume.

アップグレード時の注意

  • Dell PowerMax Driver: introduced a new configuration option, snapvx_unlink_symforce, to address Bug #2045230. See the Bug Fixes section for details.

  • [Pure Storage] Changed Python SDK driver requirement from purestorage to py-pure-client to support change to Purity//FA REST 2.x API calls.

  • The Quobyte driver has been marked as unsupported and is now deprecated. enable_unsupported_driver will need to be set to True in the driver's section in cinder.conf to continue to use it.

廃止予定の機能

  • The GlusterFS backup driver has been deprecated. It will be removed in the 2025.1 release.

  • The Quobyte driver has been marked as unsupported and is now deprecated. enable_unsupported_driver will need to be set to True in the driver's section in cinder.conf to continue to use it. As an unsupported driver, it is eligible for removal from the cinder code base if its third party CI system is not fixed.

セキュリティー上の問題

  • Images in the qcow2 format with an external data file are now rejected with an ImageUnacceptable error because such images could be used in an exploit to expose host information. Given that qcow2 external data files were never supported by Cinder, this change should have no impact on users. See Bug #2059809 for details.

バグ修正

  • Dell PowerMax driver bug #2034937: Fixed

    This change is to update the live migration ability in environments using PowerMax. In previous 2023.1 version, the live migration fails without a pool name. This update add the ability of live migration without a pool name.

  • StorPool driver bug #1939241: Fixed the creation of encrypted StorPool volumes by dropping the needlessly and incompletely overridden _attach_volume() and _detach_volume() methods.

  • Bug #2027532: Fixed Cinder API HTTP 500 when issuing a volume list and sorting by a boolean field (i.e. "bootable").

  • Dell PowerMax Driver Bug #2045230: Fixed the issue that Dell PowerMax SnapVx link fails as the linked device is not yet fully defined.

    Previously, the below operations could fail if the linked device was not yet fully defined at the time of the call. Now, when snapvx_unlink_symforce is enabled, those operations are not interrupted by not fully defined devices.

    By default, snapvx_unlink_symforce is False. Use extreme caution with this option. If used when a link is copy in progress or when a restore is restore in progress, this will cause an incomplete copy and data on the copy target would not be usable.

    Impacted operations:

    • Clone a volume

    • Create a volume from a snapshot

    • Create volume snapshots

    • Delete volume snapshots

    • Revert volume to snapshot

    • Create generic volume group from source

    • Unmanage volumes

  • Bug #2058596: Fixed broken backup_swift_service_auth=True which made swift backup driver consistently fail during object data access.

  • Bug #2059809: Fixed issue where a qcow2 format image with an external data file could expose host information. Such an image is now rejected with an ImageUnacceptable error if it is used to create a volume. Given that qcow2 external data files were never supported by Cinder, the only use for such an image previously was to attempt to steal host information, and hence this change should have no impact on users.

  • Bug #1938488: When cleaning up a failed backup, clean up the snapshot status when the backup source is a snapshot

  • StorPool driver bug #2002995: When retyping a volume on a StorPool backend to a different volume type also on that StorPool backend but using a different StorPool template, occasionally the retype operation would fail or the old volume could be left attached to a StorPool client. This issue has been fixed in this release.

  • Bug #2031897: Fixed issues for volume backups with the Ceph driver where failures of the first process ("rbd export-diff") were not caught. Instead, only the return code of the second process ("rbd import-diff") was recognized.

    This change also preserves the stderr that was lost previously in order to ease debugging.

  • Hitachi driver bug #2063317: Fix test scripts to avoid failing by unexpected response from psuedo REST API server

  • HPE 3PAR driver bug #2021941: Fixed: Now clone of replicated volume can be created

  • HPE 3PAR driver Bug #2068795: Fixed: Perform login before invoking getWsApiVersion

  • HPE 3PAR driver bug #2044255: Fixed: In peer persistence setup, when volume is attached to instance, now LUN ids are returned from both the arrays.

その他の注意点

  • Enabled Guru Meditation Reports on Cinder wsgi. When running Cinder under WSGI, we might want to have Guru Meditation Reports as well as when running outside of WSGI.
