I have a mismatch_cnt of 384 on a 2-way mirror. The box runs 2.6.17.4 and can't really be rebooted or have its kernel updated easily 1) Where does the mismatch come from? The box hasn't been down since the creation of the array. 2) How much data is 384? Blocks? Chunks? Bytes? 3) Is the "repair" sync action safe to use on the above kernel? Any other methods / additional steps for fixing this? Regards, C.
