Thanks for your answer, to be sure that the memory isn't in cause (or if it was, that it wouldn't bother me) i've already commanded ecc memory. But what I don't understand is why btrfsck doesnt correct anything ? It detects that X have a bad block, a bad leaf and all. The "bad blocks" doesn't change between the two run of fsck (event after a reboot), why it doesn't devalidate this block in the btree ?
