Igniters,
Do we have some feature allows to check nodes aliveness on a regular basis?
Scenario:

The cluster has no load but some node's JVM crashed.

another node) and waits for some timeout t
This is one of the functions of the DiscoverySPI. Nodes check on their
neighbours and notify the remaining nodes if one disappears. When the topology
changes, it triggers a rebalance, which relocates primary partitions to live
nodes. This is entirely transparent to clients.
It gets more complex

Could you explain how this works in detail?
How can I set/change check frequency?

Other people would be better placed to discuss the internals.

Will it detect node failure on still cluster?

Yes. Nodes are always chatting to each another even if there are no requests
coming In.
Here’s the status message:

That's cool.
I'm waiting for this thing.

Hi everyone.
I think we should check behavior of failure detection with tests or find
them if already written. I’ll research this question and rise a ticket
if a reproducer appears.

Evgenii,
Have you had a chance to look into the reproducer?

Thanks for the hint.

Hi, Maxim!
It is very useful feature, great job!
But could you explain me some aspects?
- Does snapshot contain only primary data or backup partitions or both?
- Could I create snapshot from m-node cluster and apply it to n-node
cluster (n<>m)?
- Should data node has extra space on pe

A snapshot contains a full copy of persistence data on each local
node. This means all primary, backup partitions

Let's remove "This operating system has been tested less rigorously"

It does not make sense:

I've seen this behaviour before, it occurs on massive data loading to a
cluster with a small data region. It's not reproducible with data regions
with normal sizes, I think that this is the reason why this issue is not
fixed yet.
