So, if I understood what you have said correctly, then the following would be true: - When there is no I/O being performed on the RAID, and then one of the member disks becomes disconnected for some reason, then a dmeventd event would not be generated. - After a while, I/O does get performed on the RAID (with a member disk disconnected), then that will be the time that a dmeventd event gets generated.
