Erasure Coding Improvements — Swarm 14 includes Erasure Coding related improvements:
With Swarm 14.0 indexed erasure coded (EC) objects include the field "ec_encoding" which records the current EC coding of the object. Non-EC objects do not have this field. (SWAR-6653)
Swarm now computes the data footprint of Erasure Coding EC segments and whole replicas objects separately during each HP cycle so the relative space usage of whole replicas vs EC can inform space usage policy decisions. (SWAR-9160)

Impacts for 14.0Change in the node.cfg file — The previously deprecated sysctl section of the node.cfg file is removed. Use kernel.sysctlFileUrl (introduced in Swarm 12.0) instead if it is necessary to set kernel runtime parameters, . (SWAR-8968) Settings changes Updated: All sysctl.* settings are removed. (SWAR-8968) support.reportPeriod default is changed to 21600 (6 hours). (SWAR-8424)
The following settings are now persisted cluster settings that can be updated via SNMP and the UI (SWAR-9115)
cluster.enforceTenancy
cluster.proxyIPList
ec.maxManifests
ec.minParity
ec.segmentSize
feeds.retry
health.parallelWriteTimeout
health.underreplicationAlertPercent
health.underreplicationTolerance
health.persistentUnderreplicationAlertPercent
log.obscureUUIDs
scsp.clientPoolTimeout
scsp.defaultContextReplicas
scsp.defaultROWAction
scsp.maxWriteTime
scsp.validateOnRead
search.numberOfShards
Swarm storage node metrics are deprecated and are replaced in the next major release by the graphs and reporting from Grafana and Prometheus Node Exporter. The storage administration UI is updated to allow for metrics to be turned off. Clear metrics.target from the configuration, uninstall caringo-elasticsearch-metrics, and issue the following cURL to clear the space in the Elasticsearch cluster. (SWAR-8982) | Code Block |

to clear the space in the Elasticsearch cluster. (SWAR-8982)Differences in scsp.forceLegacyNonce configuration depending on the version upgrading from (SWAR-9020): Currently running a Swarm Storage version prior to 11.1, and upgrading to 11.1, 11.2, 11.3, 12.0 or 12.1: Before upgrading, set scsp.forceLegacyNonce=true in the node.cfg file. After the upgrade, when the cluster is fully up, update scsp.forceLegacyNonce=false using swarmctl and change scsp.forceLegacyNonce=false in the node.cfg file. Currently running a Swarm Storage version 11.1, 11.2, 11.3, 12.0 or 12.1 and upgrading to another version from that list: Before upgrading, verify scsp.forceLegacyNonce=false is in the node.cfg file and verify using swarmctl that scsp.forceLegacyNonce=false in a cluster. Subcluster assignments can no longer be blank, and CSN installations with mixed subcluster assignments have the unassigned nodes unable to boot, showing an error in contacting the time source. Supply a subcluster for each node if any named subcluster is specified in a cluster. (SWAR-7675)

The Storage UI shows no NFS config if the Elasticsearch cluster is wiped. Contact DataCore Support for help repopulating the SwarmFS config information. (SWAR-8007)
Any incomplete multipart upload into a bucket leaves the parts (unnamed streams) in the domain if a bucket is deleted. To find and delete them, use the s3cmd utility (search the Support site for "s3cmd" for guidance). (SWAR-7690)
Invalid config parameters that prevent the unassigned nodes from booting are created if subcluster assignments are removed in the CSN UI. (SWAR-7675)
False 404 Not Found and other SCSP errors may display during rolling reboot in versions 11.1 through 12.0.1. Set scsp.forceLegacyNonce=False in the cluster configuration to mitigate this problem. This setting needs to be removed before upgrading to 12.1.0 or later. (SWAR-9020)
S3 Backup restoration to the cluster may be blocked if the certificate is not located where Swarm expects it when using certificates with HAProxy. From 12.1, a clearer error message draws attention to the issue for S3 backup and replication feeds that are blocked due to invalid X.509 ("SSL") certificates. (SWAR-8996)
