Hi, There is not much information in this log file. Which server's file is this? I will need to see the rebalance logs from both nodes.
It sounds like there are a lot of files on the volume which is why the rebalance will take time. What is the current rebalance status for the volume? Rebalance should not affect volume operations so is there a particular reason why the estimated time is a cause of concern?
