See [DRAFT] Third-Party Components for Storage 17.0 for the complete listing of packages and versions for this release.

New Features

  • Internode communication: Internode communication has been optimized for better load handling.

  • Emergency Defragmentation: A new setting has been introduced to enable high-priority defragmentation without extra configurations.

  • RPC enhancement: RPC calls to handle [Rishab is adding more and Anjali work with Rishab]

New Settings

  • New Setting (node.maxRPCPollsLost): Resolved Swarm node reboots under load by introducing node.maxRPCPollsLost to throttle on RPC status loss. (SWAR-10319)

  • New Setting (disk.enforceEmergencyDefrag): Added disk.enforceEmergencyDefrag setting to enable high-priority defragmentation without additional configurations. (SWAR-9276)

New Headers

  • New Headers: Rishab to add more here

Fixed in 17.0

  • Default PDI Enablement: Per Domain Indexing (PDI) is enabled by default. (SWAR-10359)

  • ES8 Support: Swarm supports Elasticsearch (ES) 8 and later, starting from Storage 17.0. (SWAR-9536)

  • Search Feed Deletion Improvement: Deleting a Search Feed created with search.perDomainIndex=True now removes all associated domain indices in Elasticsearch. Use the Storage UI for this, not the legacy port 90 console. (SWAR-10264)

  • Uninitialized / Used disks: To prevent potential data loss when hot-plugging partitioned, used, or unformatted disks/volumes, DataCore recommends checking and formatting the disk before attaching it to a Swarm Storage Node. (SWAR-10206)

  • Memory Leak Fix: Fixed memory leak issue which occurred over time in the loaded cluster. (SWAR-10124)

  • Node Reboot During Heavy Load: Fixed an issue that caused Swarm Storage Nodes to reboot under heavy load due to SCSP process failures. (SWAR-10319)

  • Recovery Failure: Fixed an issue where volumes pending for mount were added to the recovery suspend list, causing no recovery. (SWAR-10061)New Setting (disk.enforceEmergencyDefrag): Added disk.enforceEmergencyDefrag setting to enable high-priority defragmentation without additional configurations. (SWAR-9276)

  • SSD Trim Support: Storage nodes support SAS and SATA-based SSDs, starting from Storage 17.0. (SWAR-9883)

  • New Setting (node.maxRPCPollsLost): Resolved Swarm node reboots under load by introducing node.maxRPCPollsLost to throttle on RPC status loss. (SWAR-10319)New API Schema fields: Added new API schema fields (usedMBytes, trappedMBytes, and usedSpaceMB) from Storage 17.0.

  • 409 Error Due to Full Volumes: Swarm keeps trying to use full volumes and occasionally the retry fails with a 409 error under heavy load scenarios. (SWAR-10249)

  • CIP Settings Update: Verify cip.processes = 2, update the setting cip.readRetries=7, cip.deleteRetries=7, and cip.replicastRetries=7 to mitigate the False 404s: Fixed false 404s error that occurs sometimes in Swarm responses during heavy load situations. (SWAR-10120)
