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

B) as time permits read the links in that section, I think the ones some of us want you to read are:
and a couple of supplementals:

What did the boss say would "be dangerous and ... would destroy all data"
i.e. what command and options would the boss not let you run?

It is a bit hard to comment on that which is not here.

Is the boss more qualified to be administrating the machine in critical times like this than you**?
If so, then it is most likely time to hand him the keyboard and tell him he gets to keep the bits
that are left intact (both before he starts typing and after).
Will there be someone who you both trust to work on the machine in this state coming into the office

I would expect that anyone who is willing to help you over email would want at least the following
questions answered:
Which kind of file system is being used on the volume having trouble?
Do you have backups?
Is the volume small enough and do you trust yourself enough with dd to duplicate it off to a
USB|firewire|esata disk? (now THIS _is_ risky. :)
have you read `man fsck` to see why it was being suggested to run it WITHOUT the a or p options?

** The boss "...said that would be dangerous and it would destroy all data..." comment, indicates to
me that either you or he or both think that.
