cnosdb

Why does cnosdb cluster failed to initialize the default tenants?

I'm trying to run CnosDB cluster mode on my PC, but it crushed on start and throw an error: make dbms: Meta { source: TenantNotFound { tenant: "cnosdb" } }, seems failed initializing the default tenant.

Version: cnosdb 2.3.0, revision f4b52408171467c5ea2b2f75480deecc6f6ad733

Configurations

I have these two configurations:

Node - meta_1

Config for meta node:

id = 1
host = "127.0.0.1"
port = 8901

snapshot_path = "/tmp/meta_1/snapshot"
journal_path = "/tmp/meta_1/journal"
snapshot_per_events = 500

[log]
level = "info"
path = "/tmp/meta_1/logs"

[meta_init]
cluster_name = "meta_1"
admin_user = "root"
system_tenant = "cnosdb"
default_database = ["public", "usage_schema"]

[heartbeat]
heartbeat_recheck_interval = 300
heartbeat_expired_interval = 600

Node - data_1

Config for data node:

host = '127.0.0.1'

[cluster]
name = 'data_1'
http_listen_port = 8912
grpc_listen_port = 8913
flight_rpc_listen_port = 8914
tcp_listen_port = 8915
meta_service_addr = ['127.0.0.1:8901']

[node_basic]
node_id = 1
cold_data_server = false
store_metrics = true

[deployment]
mode = 'query_tskv'
[query]
[storage]
path = '/tmp/data_1/data'
[wal]
path = '/tmp/data_1/wal'
[cache]
[log]
level = 'info'
path = '/tmp/data_1/wal'
[security]
[hinted_off]
[heartbeat]

I‘ve just checked the configurations and i've made sure that the meta_1 listens on 127.0.0.1:8901 and, the data_1 is connecting to 127.0.0.1:8901, but I'm puzzled by the output messages.

Solution

  • In the configuration file of datanoe, ensure that the name in both [cluster] section with name='data_1' and [meta_init] section with cluster_name="meta_1" are the same. Otherwise, it will consider them as two separate clusters.
