Well , Thanks for your suggestions. <br><br>1.Which kind of file system is being used on the volume having trouble?<br> A: it uses the ext2fs filesystem on CentOS 4.6 x86_64<br><br>2.Do you have backups?<br>A: that server is used to backup other servers data , so itself has not any backups<br>
<br>3.Is the volume small enough and do you trust yourself enough with dd to
duplicate it off to a<br>
USB|firewire|esata disk? (now THIS _is_ risky. :)<br><br><br>4.have you read `man fsck` to see why it was being suggested to run it
WITHOUT the a or p options?<br>A: Yeah ~ I have read that . In particular , "-p" options ,. This option is mainly provided for those sysadmins<br>who don't want to repartition the root system to be small and compact( which is really the right solution)<br>

A) as Nicolas HINTED please read the _text_ that follows "Guidelines for CentOS Mailing List posts" at<br>

<br>
</div>B) as time permits read the links in that section, I think the ones some of us want you to read are:<br>
<a href="http://www.caliburn.nl/topposting.html" target="_blank">http://www.caliburn.nl/topposting.html</a><br>
and a couple of supplementals:<br>

</div>What did the boss say would "be dangerous and ... would destroy all data"<br>
i.e. what command and options would the boss not let you run?<br>
<br>
It is a bit hard to comment on that which is not here.<br>
<br>
Is the boss more qualified to be administrating the machine in critical times like this than you**?<br>
If so, then it is most likely time to hand him the keyboard and tell him he gets to keep the bits<br>
that are left intact (both before he starts typing and after).<br>
Will there be someone who you both trust to work on the machine in this state coming into the office<br>
soon?<br>
<br>
<br>
I would expect that anyone who is willing to help you over email would want at least the following<br>
questions answered:<br>
Which kind of file system is being used on the volume having trouble?<br>
Do you have backups?<br>
Is the volume small enough and do you trust yourself enough with dd to duplicate it off to a<br>
USB|firewire|esata disk? (now THIS _is_ risky. :)<br>
have you read `man fsck` to see why it was being suggested to run it WITHOUT the a or p options?<br>
<br>
<br>
<br>
** The boss "...said that would be dangerous and it would destroy all data..." comment, indicates to<br>
me that either you or he or both think that.<br>
