My assumption was due thinking that parity is never being used when RAID5 is in "healthy" mode. But anyway, please clear it up: if I've made --asume-clean RAID5 array, formatted it with some FS (or even LVM), and put OS/data to it, then (in idle at night, for e. g.) run "resync", would that be the same valid result (overall data integrity) as if I had previously created it without "--asume-clean" at all? (Let's suppose hard disks were healthy in both cases :-) And Neil, using the chance to have your reply :-) I'd like to ask one more question: is that true (I think and hope it is!) that MD doesn't read/write full chunk size when it's just to read/write another block of data and hence chunk size only affects data interleaving on disks. P. S. Is there someone on this list who can share his linux-RAID archive in mbox format? From time to time I find interesting discussions have been going but can't just hit "Reply". If you can help me with that, please reply personally (not CC:ing to the list). Thanks! -- End of message.
