  • Remove --generate-key option in neofs-cli container delete (#1692)
  • Serving ControlService.NetmapSnapshot RPC (#1793)
  • control netmap-snapshot command of NeoFS CLI (#1793)

Updated

  • neofs-contract to v0.16.0
  • neofs-api-go to v2.14.0

Updating from v0.32.0

Replace using the control netmap-snapshot command with netmap snapshot one in NeoFS CLI. Node can now specify additional addresses in ExternalAddr attribute. To allow a node to dial other nodes external address, use apiclient.allow_external config setting. Add --force option to skip placement validity check for container creation.

Pass maintenance state to neofs-cli control set-status to enter maintenance mode. If network allows maintenance state (), it will be reflected in the network map. Storage nodes under maintenance are not excluded from the network map, but don't serve object operations. () can be fetched from network configuration via neofs-cli netmap netinfo command.

To allow maintenance mode during neofs-adm deployments, set network.maintenance_mode_allowed parameter in config.

When issuing an object session token for root (virtual, "big") objects, additionally include all members of the split-chain. If session context includes root object only, it is not spread to physical ("small") objects.

neofs-node configuration now supports mode: disabled flag for a shard. This can be used to temporarily ignore shards without completely removing them from the config file.

NEOFS_IR_CONTRACTS_ALPHABET_AMOUNT is not mandatory env anymore. If it is not set, Inner Ring would try to read maximum from config and NNS contract. However, that parameter still can be set in order to require the exact number of contracts.

Shard configuration records were renamed:

  • refill_metabase -> resync_metabase
  • writecache.max_size -> writecache.max_object_size
  • writecache.mem_size -> writecache.memcache_capacity
  • writecache.size_limit -> writecache_capcity
  • blobstor.blobovnicza.opened_cache_size -> blobstor.blobovnicza.opened_cache_capacity
  • *.shallow_depth -> *.depth
  • *.shallow_width -> *.width
  • *.small_size_limit -> *.small_object_size

Specify storage subnetworks in NEOFS_NODE_SUBNET_ENTRIES as the list of integer numbers. To exit default subnet, use NEOFS_NODE_SUBNET_EXIT_ZERO=true
