Hello, all!
Recently I've started to see the following logs in messages:
Mar 8 12:00:24 localhost smartd[795]: Device: /dev/ad4, 2 Currently unreadable (pending) sectors
Mar 8 12:00:24 localhost smartd[795]: Device: /dev/ad4, 2 Offline uncorrectable sectors
smartctl did really show that something is wrong with my HDD, but still no
remaps - just read errors.

Now can I find out which file owns the LBAs 222342557 and 222342559 ? How do I
force remapping of these sectors? I assume that I have to write something
directly to the sectors?
Thank you all in advance!
