Question about cpu usage and disk read speed on activation stage.

[yangjiajun <13...@qq.com>]

Hello.

Ignite takes about 1 hour to activate on my machine.I  have only one node
and use version 2.6.I also enable persistence and use 22GB heap memory and
22GB off-heap memory.My machine has 16 cores.The cpu usage is very low(<%1)
and the disk read speed is about 1M/s~6M/s while ignite is activating.Is
disk a bottleneck?Or should I tune some settings of ignite?

Hi,

I was wrong. You can activate the cluster with not full baseline topology.

Looks like you that your node that stopped during checkpoint and it is a
reason of long recovery of the binary memory that takes a lot of time.

Here is a ticket that should optimize this process:

https://issues.apache.org/jira/browse/IGNITE-10749

Hi,

I see from your log that you have two nodes in your baseline:

[23:36:58,866][INFO][main][GridDiscoveryManager]   ^-- Node
[id=B3234010-F5BE-49CA-A57F-6676622BFF48, clusterState=INACTIVE]
[23:36:58,867][INFO][main][GridDiscoveryManager]   ^-- Baseline [id=2,
size=2, online=1, offline=1]
[23:36:58,867][INFO][main][GridDiscoveryManager]   ^-- 1 nodes left for
auto-activation [2e3bc707-ac4c-4ba6-a0c2-1867c6ea8272]

node 1 with id = B3234010-F5BE-49CA-A57F-6676622BFF48 was started.
node 2 with id = 2e3bc707-ac4c-4ba6-a0c2-1867c6ea8272 was offline.

So cluster with persistence will be activated only when all nodes from
baseline will be online.

You can read about it here:

Hi,

Could you share you Ignite node configuration and logs from startup?

BR,
