Hey Jeff, As long as you set the maintenance flags (noout/norebalance) you should be good to take the node down with a reboot Regards, Bailey

I have a Nautilus cluster with 7 nodes, 210 HDDs. I recently added the 7th node with 30 OSDs which are currently rebalancing very slowly. I just noticed that >the ethernet interface only negotiated a 1Gb connection, even though it has a 10Gb interface. I’m not sure why, but would like to reboot the node to get the >interface back to 10Gb.
Is it ok to do this? What should I do to prep the cluster for the reboot?
