This is being triggered by my Debian config, but before I nuke it I'd like to know a little more. If a real disk error happens during this rebuild on a raid5, would the disk go into regular degraded mode or would it count as a double fault? I also noticed that recently all the checks for all the arrays happen simultaneously. That's bad because most of them share the same physical disks. Am I imagining this or was the system smart enough to do them one after another until recently? Do you do period checks? I get lots of device mismatches reported but apparently that's normal if there's write activity. The whole thing sound contra-productive to me and might panic new users.
