2024.1 Series Release Notes

24.0.0-1

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.

24.0.0

新機能

• Dell PowerFlex driver: Enabled cinder volume active/active support. This allows users to configure Dell PowerFlex backends in cinder clustered environments.

• Dell EMC PowerMax driver: Added SRDF powermax:disable_protected_snap volume-type extra-spec property for the purpose of avoiding overconsumption on both source and target storage arrays.

  An operator may enable this functionality by creating a specific volume type with the property:

  "powermax:disable_protected_snap": "<is> True"
  

  When disabled (which is the default and current behavior), a replicated source volume will be protected with a snapshot of the same volume type.

  When enabled, snapshots of replicated source volumes will be treated as regular, non-replicated devices.

• Add the new os-extend_volume_completion volume action, which the Nova compute agent can use to notify Cinder that it has finished handling the volume-extended external server event.

• Fujitsu ETERNUS DX driver: Added support to extend a volume on RAID Group using CLI.

  Revised the 'Extend Volume' process on the RAID Group to improve processing speed as follows:

  • When extending a volume created on ThinProvisionPool, the process will still use SMI-S for volume extension.

  • When extending a volume created on RaidGroup, the process has been updated to use CLI for volume extension.

• NetApp iSCSI/FCP drivers: NetApp space allocation feature allows ONTAP and host to see the actual space correctly when host deletes data. It also notifies the host when the LUN cannot accept write data due to lack of space on the volume, and makes the LUN read-only (rather than going offline). This feature can be enabled or disabled on cinder volumes by using volume type extra specs with the netapp:space_allocation property.

• Open-E JovianDSS driver: revert-to-snapshot has been removed.

• Dell PowerMax driver: Enabled support for Active/Active to both FC and iSCSI driver. This allows users to configure Dell PowerMax backends in clustered environments.

• Pure Storage driver: Allow synchronously replicated volumes to be created during a replication failover event. These will remain viable volumes when the replication is failed back to its original state.

アップグレード時の注意

• Infinidat driver: support has been removed for pre-v3.0 InfiniBox systems. These versions are end of life and have not been supported for a long time.

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

• The enable_unsupported_driver option will need to be set to True in the driver's section in cinder.conf to continue to use the following three drivers.

  • Dell SC Series Storage Driver (iSCSI, FC)

  • Dell VNX Storage Driver (FC, iSCSI)

  • Dell XtremeIO Storage Driver (iSCSI, FC)

• The following drivers have been marked as unsupported and are now deprecated. enable_unsupported_driver will need to be set to True in the driver's section in cinder.conf to continue to use these drivers.

  • Windows iSCSI Driver

  • Windows SMB Driver

• Cinder now uses the RBD trash functionality to handle some volume deletions. Therefore, deployments must either a) enable scheduled RBD trash purging on the RBD backend or b) enable the Cinder RBD driver's enable_deferred_deletion option to have Cinder purge the RBD trash. This adds the new configuration option 'rbd_concurrent_flatten_operations', which limits how many RBD flattens the driver will run simultaneously. This can be used to prevent flatten operations from consuming too much I/O capacity on the Ceph cluster. It defaults to 3.

廃止予定の機能

• The following three drivers were marked unsupported. These drivers are deprecated and will be removed in a future release.

  • Dell SC Series Storage Driver (iSCSI, FC)

  • Dell VNX Storage Driver (FC, iSCSI)

  • Dell XtremeIO Storage Driver (iSCSI, FC)

• Support for running Cinder in Windows operating systems has been deprecated because of retirement of the Winstackers project.

• The following drivers have been marked as unsupported and are now deprecated.

  • Windows iSCSI Driver

  • Windows SMB Driver

バグ修正

• Bug #2008017: Hide value of the [coordination] backend_url option from logs because it can contain credential.

• Bug #2016138: Handle missing volumes during cleanup of incomplete backups.

• Infinidat driver bug #2017815: Fixed Infinidat driver to inherit compression setting by default for all newly created volumes. Admin can set True or False for the infinidat_use_compression option in the driver section of cinder.conf to explicitly enable or disable compression setting for all newly created volumes. Or leave this option unset (commented out) for all created volumes to inherit their compression setting from their parent pool at creation time. The default value is unset.

• 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

• PowerMax Driver bug #2051830: REST API calls to the PowerMax backend did not have a timeout set, which could result in cinder waiting forever. This fix introduces two configuration options, rest_api_connect_timeout and rest_api_read_timeout, to control timeouts when connecting to the backend. The default value of each is 30 seconds.

• PowerFlex Driver bug #2052995: REST API calls to the PowerFlex backend did not have a timeout set, which could result in cinder waiting forever. This fix introduces two configuration options, rest_api_connect_timeout and rest_api_read_timeout, to control timeouts when connecting to the backend. The default value of each is 30 seconds.

• Dell PowerMax driver bug #2051828: The driver only recognized 10.0 as being Unisphere 10 and would try to use 9.2 for Unisphere 10.x (where x > 0), but now it correctly recognizes 10.x as being Unisphere 10.

• Bug #2045431: Fixed a data leak scenario where we preserve sparseness when reimaging the volume.

  We currently do a sparse copy when writing an image on the volume. This could be a potential data leak scenario where the zero blocks of the new image are not written on the existing volume and the data from the old image still exists on the volume. We fix the scenario by not doing sparse copy when reimaging the volume.

• Bug #2036994: Fixed rollback of volume status if the reimage operation fails while checking image metadata.

• Bug #1948962: Fixed operations that failed on volume types with 255 characters names (e.g. set quota limits or volume migrate).

• Hitachi driver bug #2024418: Fixed to raise correct exception when volume is busy while performing delete volume operation.

• HPE XP and NEC V driver bug #2012515: Fixed to use correct Host group name.

• Hitachi driver bug #2011810: Fixed to use correct pool number for secondary storage on GAD environment.

• HPE 3PAR driver Bug #2045411: Added support for ipv6 address in the 3PAR iSCSI driver.

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

• HPE 3PAR driver Bug #2026718: Fixed: With this patch, added logic to fetch correct volume name on 3par (osv_name), rcg_name and vvset_name (for particular scenarios); so that volumes can be identified and deleted from 3par.

• Bug #1988942: Increased size of volume image metadata values accepted by the Block Storage API. Volume image metadata values were limited to 255 characters but Glance allows up to 65535 bytes. This change does not affect the database tables which already allow up to 65535 bytes for image metadata values.

• Dell EMC PowerMax driver bug #1980870: Fixed potential deadlock when moving volumes between Storage Groups.

• Pure iSCSI & FC driver bug #2006960: Fixed attaching LUNs greater than 255. Driver leverages new os-brick functionality to specify LUN addressing mode.

• [Pure Storage] Bug #2035404: Fixed issue with missing replication pod causing driver to fail on restart.

• Pure Storage Cinder Driver: Fixed bug 2029005 to correctly disconnect a sync replicated volume from host on the secondary array when uniform option is set to True.

• Bug #1952420: Fixed quota warnings about backups and backup_gigabytes when creating backups.

• Bug #1969643: The RBD driver can now delete volumes with other volumes cloned from it (or its snapshots) in cases where deletion would previously fail. This uses the RBD trash functionality.

その他の注意点

• Nimble driver: Enable thin provisioning as default method while creating volumes.

• Open-E JovianDSS driver: general rework of volume and snapshot creation and deletion.

• Open-E JovianDSS driver: network interfaces selection on JovianDSS storage has been reworked.

• [Pure Storage] user_agent string changed from reporting kernel version to operating system distro and version.
