<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>Thank you very much for the insight.</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>

<p>Yes, as Pavel said, "remount-ro" is just what happens
if the filesystem encounters an error which presumably
it hasn't, at this point. :)<br>

<p>First line: mount without options from initrd.
Second: remount "/" with options from fstab.<br>
</p>
<p>It's not mean what it mounted in ro mode.<br>
