    <p>It's just an information string. Not an error. In first time root
      device mounted with options from kernel cmdline. You can see
      mounted device and options in first line. Next time (second line)
      it's remounted with options from /etc/fstab. Again: second line
      inform you, what root device remounted with option
      "errors=remount-ro". Not in ro mode.<br>
    </p>
    <p>For example, from my dmesg:</p>
    <p>
      <blockquote type="cite">[    5.395258] EXT4-fs (md2): re-mounted.
        Opts: errors=remount-ro</blockquote>

        <div>Pavel,</div>
        <div><br>
        </div>
        <div>Thank you very much for the insight.</div>
        <div><br>
        </div>
        <div>I see what you are saying (I did not know that), that the
          first mount / attributes came out initrd. It probably happens
          while dracut re-pivots initrd's / to hard drive's /.</div>
        <div><br>
        </div>
        <div>Anyway, it should be checked. It says: error, then it says
          that it remounted sda1 with EXT4-fs as RO (I assume it is /).
          I do not see very often this line in dmesg (but I see it as
          seldom occurrence), so it must be some sort of race effect,
          or...?!</div>
