I was expecting more of a general view since I'm a new user. Sorry I wasn't clear. What sort of events cause the Event counter to increase? If it's mainly whenever the superblock is updated then my question is: What sort of events cause the superblock to be updated? I can imagine detection of failed disk, read errors, array checks, commands by user/admin, assembly-reassembly etc? If an array operates fine for months - without user intervention, will the Event counter increase at all? Thanks. -- Jorge
