Ignite Cluster Snapshots
We are using Ignite version 2.10 and trying to create cache snapshots using java https://ignite.apache.org/docs/latest/persistence/snapshots#restoring-from-snapshot
We have a 3 nodes cluster running on three different servers.
ignite.snapshot().createSnapshot("snapshot_02092020")
But it doesn't create snapshot for the 3 nodes but just the node where it is executed. Is this expected? Is there a way to create snapshot for the whole cluster as mentioned in the documentation - https://ignite.apache.org/docs/latest/persistence/snapshots#overview
Thanks,
Siva.

RE: Ignite Cluster Snapshots
Posted by si...@barclays.com.
My Bad. Snapshots are actually created on individual servers. Are there any best practices to follow when we are taking snapshots. How do we ensure that all the cache updates are written to disk before we take the snapshot?

Hi, Siva!
As I see, it is not expected behaviour.
Is cluster baseline topology correct and all nodes are in the cluster? To check this, you can run the 'control.sh --baseline' command.
Have you checked logs for errors on all nodes of the cluster?
Is the above behaviour the same when creating snapshot via the control script (control.sh|bat)?
