I have a cluster in a data center that is doing power maintenance which has the possibility that all power will go out. The data center is performing the work midday over the course of a couple days so we cannot shut down preventatively.
My question is: Do the nodes do any sort of checkdisk once power returns, or does it just flush the NVRAM to disk and carry on (assuming the cluster comes up fine and there is quorum)?
Is there anything else I should expect or plan for when the cluster comes back online?
Thank you!
