Additional Changes

Changes include versions and fixes coming from testing and user feedback:

OSS Versions

See Third-Party Components for Storage 15.3 for the complete listing of packages and versions for this release.

Fixed in 15.3

• Improved Stability for Dense Clusters: Improved CPU utilization in dense clusters which reduces spontaneous process restarts and other instabilities. (CUP-630)

• Improved Handling of S3 Multi-Deletes: Addressed a multi-delete ES ghost entry bug impacting various Veeam-using customers. (SWAR-9703)

• EC Multipart and Versioned Segments: Eliminated the potential for missing EC segments in obsolete EC object versions. (SWAR-9770)

• Finalizing State on Restart/Shutdown: Fixed an issue where a node did not finalize the state during restart or shutdown. Instead, the node required manual power for cycling, which should no longer be necessary. (SWAR-9767)

• Network Disruption: Eliminated potential for data loss when a cluster had significant network disruption that continued for multiple HP cycles. (SWAR-9753)

• EC Conversion: Fixed a rare cause of segment loss when EC conversions interleaved with volume recoveries. (SWAR-9751)

• Elasticsearch Upgrade: Swarm Storage 15.3 requires upgrading Elasticsearch to 7.17.9. The rolling upgrade of the Elasticsearch cluster can be done either before or after upgrading to Storage 15.3. (SWAR-9731)

• Retention Policies: Fixed an issue where updates to retention policies that failed, typically due to network-related issues, could result in the loss of the object. (SWAR-9842)

...

• The Storage UI shows no NFS config if the Elasticsearch cluster is wiped. Contact DataCore Support for help in repopulating the SwarmFS config information. (SWAR-8007)

• Any incomplete multipart upload into a bucket leaves the parts (unnamed streams) in the domain if the bucket is deleted. To find and delete those parts, use the s3cmd utility (search the Support site for "s3cmd" guidance). (SWAR-7690)

• The chassis shuts down but does not come back up when restarting a cluster of virtual machines that are UEFI-booted (versus legacy BIOS). (SWAR-8054)

• Invalid config parameters that prevent the unassigned nodes from booting are created if subcluster assignments are removed in the CSN UI. (SWAR-7675)

• On node reboots, some feed statistics that are not persisted across boots may show up incorrectly. It will fix itself eventually. Currently, there is no workaround for this. (SWAR-9720)

To upgrade Swarm 9 or higher, proceed to How to Upgrade Swarm. For migration from Swarm 8.x or earlier, contact DataCore Support for guidance.
