Changes include versions and fixes coming from testing and user feedback:
OSS Versions — See [DRAFT] 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 & 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 not no longer be necessary. (SWAR-9767)
Network disruption — Eliminated potential for data loss when a cluster had significant network disruption which 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)
