Node down in MongoAtlas

Hi,
I have a cluster (3 nodes) with MongoAtlas, and today I see this alert: “Disk I/O % utilization on Data Partition has gone above 90 on nvme1n1”… I see that one node is Down!
I search help because I don’t understand a lot of things in MongoAtlas. I try to resize my cluster to 40Gb (150 IOs) but 3 hours later I see the label “We are deploying your changes: 0 of 3 servers complete (current action: configuring MongoDB)…”
How long for this resize? I don’t understand…
How can I start the down node?

Regards
