An 'event' is one of: switch from 'active' to 'clean' switch from 'clean' to 'active' device fails device is added spare replaces a failed device after a rebuild I think that it all. None of these are meaningful for RAID0, so the 'events' counter on RAID0 should be stable. Unfortunately, the number looks like a decimal but isn't. It is a 64bit number. We print out the top 32 bits, then the bottom 32 bits. I don't remember why. Maybe I'll 'fix' it. > > How are they calculated? events = events + 1; Feel free to merge this text into the wiki.
