The DELETE operation returns the Castor-System-Delete-Marker-Etag header on a named or alias object in the versioning enabled or versioning suspended state. If versioning is disabled, the object is immutable or a context, and no such header is returned. The ETag of the delete marker (returned) is checked by INFO-ing the deleted object and checking the returned ETag header. (SWAR-9292)
...
If the container is versioning disabled or versioning suspended, deletion of the current version fails, as before, with a 403.
If the container is versioning enabled, the delete succeeds and creates a delete marker, leaving the former current version as the first non-current version.
...
Swarm provides a setting (ec.convertToPolicy) to enable the conversion of existing EC objects to the current policy encoding. (SWAR-9203)
Additional Changes
Changes include versions and fixes coming from testing and user feedback:
OSS Versions — See Third-Party Components for Storage 14.1.2 for the complete listing of packages and versions for this release.
Fixed in 14.1.2
Replication and S3 backup feed: The feed is no longer reported as blocked for long-running replications (SWAR-9218). The object replication is allowed for custom metadata containing Non-ASCII characters. (SWAR-9212)
Bucket and domain renaming: Swarm supports renaming of query arguments and bucket and domain using alias UUID. Renaming works with COPY, PUT, and APPEND operations, though COPY with the preserve query argument is advised. If a bucket or domain collision is detected, rename either context without colliding with each other. (SWAR-8708)
Bulk configuration: Swarm provides bulk Elasticsearch 7 nodes configuration to consistently use discovery.seed_hosts, not older discovery.zen settings. (SWARM-9395)
nicTable: It is populated again in SNMP; multiple new columns were added. (SWAR-9327)
SNMP certain communication stats:Swarm now publishes via SNMP communication stats summarized over a moving window covering the last hour. A new daily stats table in SNMP publishes both communication and network interface stats summarized over a moving window covering the last day. The daily stats are updated every hour. (SWAR-8124)Large physical memory support: The EFQ02 errors are not received in logs while running 14.1 release on nodes with large physical memory (>116G). (SWAR-9353)
NTP dependency: NTP dependency checks are improved for configured time servers that either fail to respond quickly or respond using an older NTP version. (SWAR-9373)
USB Booting - Swarm 14.1.1 now supports booting from a USB drive. This was not working in 14.1.0. (SWAR-9419)failing on gems cluster — Remote replication feed cannot replicate objects in the versioned buckets.
Upgrade Impacts
Required
Complete the migration to Swarm 11.3 and ES 6.8.6 before upgrading to Swarm 14 if running older Elasticsearch (5.6.12 or 2.3.3). See here for upgrading from an unsupported Elasticsearch version.
These items are changes to the product function that may require operational or development changes for integrated applications. Address the upgrade impacts for each of the versions since the currently running version:
