Not quite, esp. not in the case of interrupted sync. in that case you've got one disk with valid data and another disk known to contain nothing usable. Disk1 Disk2 aaaaaaaaaa aaaaabbbbb If the information that disk2 is currently NOT usable isn't preserved bad things might happen on resume - I don't think a result of Disk1 Disk2 aaaaabbbbb aaaaabbbbb after resync finishes would make anyone especially happy :-) So as soon as we get into the "resume raid sync" business, even raid1 very defininitely needs in/out-of sync indicators.
