A number of important fixes are brought by this release, including protocol ones (subnet and system EACL changes), as well as an updated storage subsystem and useful CLI updates making it more powerful and user-friendly at the same time.

Some previously deprecated configuration options were removed, so be careful and this is the last minor release to support the Blobovnicza tree storage subsystem. Starting with the next minor release, the component will be purged,so be prepared (see Updating section) and migrate to more efficient and simple Peapod.

Updated

  • neofs-sdk-go to v1.0.0-rc.11

Updating from v0.37.0

CLI command timeouts (flag --timeout) now limit the total command execution time and not single network operation. If any commands suddenly start to fail on timeout, try increasing the value, for example, twice. Also note that the execution of commands with the --await flag and without an explicitly specified time period is now limited to 1 minute. This value can be changed with--timeout flag.

Histogram (not counter) RPC/engine operation handling time metrics were added. For an old engine *operation_name*_duration a new *operation_name*_time is available.For an old *operation_name*_req_duration RPC a new rpc_*operation_name*_time is available. The old ones (the counters) have been deprecated and will be removed with the following minor release.

Container estimation main node calculation has been changed. A new 32-byte long array is taken as a sorting pivot: it is an estimated container with the first 8 bytes replaced with a target epoch in a little-endian encoding now.

Deprecated morph.rpc_endpoint SN and morph.endpoint.client IR configurations have been removed. Use morph.endpoints for both instead.

Deprecated neofs_node_object_epoch metric for IR and SN (the same for both) has been removed. Use neofs_node_state_epoch for SN and neofs_ir_state_epoch for IR instead.

Deprecated --no-precheck flag in neofs-cli container set-eacl use --force flag instead for skipping validation checks.

Subnets support has been removed:

  • IR's workers.subnet and contracts.subnet configs are not used anymore.
  • SN's node.subnet config section is not used anymore.
  • neoofs-amd morph does not have subnet subcommand anymore.
  • neofs-cli container create does not have --subnet flag anymore.

Docker images now contain a single executable file and SSL certificates only.

neofs-cli control healthcheck exit code is 0 only for "READY" state.

To migrate data from Blobovnicza trees to Peapods:

$ blobovnicza-to-peapod -config </path/to/storage/node/config>

For any shard, the data from the configured Blobovnicza tree is copied into a created Peapod file named peapod.db in the directory where the tree is located. For example, /neofs/data/blobovcniza/* -> /neofs/data/peapod.db. Notice that existing Blobovnicza trees are untouched. Configuration is also updated, for example, /etc/neofs/config.yaml -> /etc/neofs/config_peapod.yaml. WARN: carefully review the updated config before using it in the application!

To store small objects in more effective and simple sub-storage Peapod, replace blobovnicza sub-storage with the peapod one in blobstor config section. If storage node already stores some data, don't forget to make data migration described above.
