Hello, Mehra. > 1. Is it stop the world process.
No, you can perform any actions. Note, topology changes will cancel snapshot create process. > 2.

Please, take a look at `—sync` option of create snapshot command (you can see help in `control.sh` output). `EVT_CLUSTER_SNAPSHOT_FINISHED` raise on snapshot create finish. > 3.

The less you change the quicker snapshot will be created. > 24 мая 2022 г., в 20:12, Surinder Mehra <[email protected]> написал(а): > > Hi, > I have 3 node ignite cluster each node contains 60G work directory(ebs) and I > need to create snapshots. > I followed steps to create snapshots and run create snapshot command using > control utility.
