Hi, We had a brute force cluster shutdown event that was followed by log recovery when the cluster went back online. The cluster took hours to split the logs and recover the regions, all of which might have made sense since we have quite a lot of regions (around 13K) but the weird thing is that there was no obvious bottleneck during the recovery process. CPU was almost idle on all the nodes, IO was on 5-20% utilization, memory was OK, network wasn't overloaded, but still it was slow. Any idea what can be slowing it down?
Thanks. -eran
