Hi, > Even "nothing"? > Why? for the following reasons: 1) the "check" command is useless if there are mismatches, harmful or harmless they could be 2) the mirroring concept implies *identical* mirrors, not identical only if the upper layer decides so 3) if a filesystem has a small bug, this will not be catched later, that is, it could be the filesystem causes a *wrong* mismatch (like there are correct ones) 4) in general, it is not safe to offer a mirroring which is not always mirroring properly > > Here we are talking about "nothing". > > Or so it seems. As I wrote, it does not matter, it is just not correct to rely on the good will of other pieces of software to guarantee the RAID-1 is working properly. The RAID-1 should work properly because it does work properly, not because the filesystem is kind enough to allow it to work properly. This could be a system design problem, not and MD one, of course, so I'm stating the Neil or others should fix the MD, what I'm writing is that it is astonishing to me that things work this way (or "walk this way"). That's it, I'm just surprised to learn such situations are present. bye, -- piergiorgio -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
