***** THE FOLLOWING WOULD WORK IN THEORY I HAVE NOT TESTED THIS ****

Boot from the install CD and go into Recovery mode.

In recovery mode it will attempt to search for an existing install. If
it see's it you will see it as /mnt/sysimage when you do a df.

Then try the following:

mkdir /mnt/sysimage/usr
mkdir /mnt/sysimage/var
cp -pR /usr/* /mnt/sysimage/usr/

Then reboot and it should get you up to some point. At that point I
would use RPM to rebuild the rpm database then update your packages as
some will most likely have to be reinstalled.

I think this will get you most of the way there - probably enough to boot if you didn't trash /etc. Unfortunately you've also trashed /var which contained your rpm database (and other important stuff - mysql databases are there by default if you run mysql, mail spools, crontab entries, /var/www, etc.).


If you have backups, then the steps enough will get you enough to boot. At that point, recover your backups on top of your running system - you've trashed all of /usr and /var so restore those first. It's important that you get the most current copies available of the /usr and /var directories. The rpm database is the most critical since it can help you determine what else is corrupted/missing. Of course the rest of the data in /var is gone unless it's on backups.

Another option, depending on what kind of system this is, is to remove the drive and put it into another system. Ideally, restore your backups to that system, boot off it, and use it to rebuild your original system disk.

If you do not have backups, boot into rescue mode (as mentioned above), and copy off all of your data including /etc and /home. Then do a fresh install (with a *lot* of luck, you may be able to do an upgrade) and reconfigure based on your backup files. I personally would not attempt to try and rebuild everything from scratch once both /usr and /var are wiped out - the time to rebuild everything will likely exceed the time to reinstall.

eric...

not to be down, but just how would i copy anything to the screwed up server, when the ssh/rcp/etc.. apps all appear to have resided in the /usr/bin dir....

i was hopeful that using the recover cd might provide a solution....

but it seems that no one has a solution, other than reinstall... which really screws me up!

If I were you, I would copy (by tar or cpio) the files from another system that has same kernel level. What else you got to loss now ?

hi...

i stupidly just did a 'rm -rf /*r' and i understand that there's no

way to


redo/undo this command.. it seems to have blown away my

/usr/bin dir..


although, for all i know, i may have screwed up a lot more...

my question, is there someway that i can reinstall the '/usr/bin'

dir.. or


am i pretty much f*ed up. i have fedora core 2. (i've asked th

question on


the FC2 list, and they leep telling me that i need to do a complete
reinstall) i thought there was a way to more or less recreate the

indoe,


or
that there was some way that you can recover if you haven't done

anything


with the drive since the 'rm -rf'... i've seen some

postings/information


on
google that kind of discuss this. but i need more understanding...

this is a critical system that i was putting alot of things on.. i

haven't


done anything else to the box after my mistake..

There are some very expensive disk recover companies out there so if it
is
very important to you I would suggest you get in touch with them they
will
do a track by track recover of data from the disk. I don't know what
filesystem they support but you can probably google for disk recovery
and
get the info. But I can tell you they are very very expensive.
