    Hi to all gurus,

    We have a redhat linux system attached to EVA5000,
    Recentely after running the e2fsck -c -c command on one of our file
    system we found that there are 3 bad blocks, The storage reported that
    there is a medium coruption. we changed the respective harddisk, but
    the file system is still showing the bad blocks, the storage team says
    that there are no harddisk errors on the EVA5000 now.

    We tried to clear the bad block list by giving the following command.
    and rerun the e2fsck, the output of both the command are attached
    below,

    we would like to know if there is any way to know the bad block number.
    so that we can run "dd" command on it to test if the physical bad block
    still exists.

    Execution 1 :

    [root@online root]# e2fsck -v -L /root/dummy /dev/sdb1
    e2fsck 1.26 (3-Feb-2002)
    Pass 1: Checking inodes, blocks, and sizes
    Pass 2: Checking directory structure
    Pass 3: Checking directory connectivity
    Pass 4: Checking reference counts
    Pass 5: Checking group summary information
    /dev/sdb1: ***** FILE SYSTEM WAS MODIFIED *****

           0 non-contiguous inodes (0.0%)

       48447 blocks used (1%)
           0 bad blocks

    Note : /root/dummy is a blank file of zero bytes

    Execution 2 :
