recover data

[richardko]

Hi,
One of the webservers that I manage crashed last week and I need to recover the data. I have the hard drive and when I try to boot it locally I get "kernel panic". I dont have the exact error.
I tried to set it up as a slave drive. The ide cable for the computer I was trying to set it up on had only two cable connections. One for Regular Master drive and the second one for the cd-rom. I disconnected the one for cd-rom and connected it to the crashed drive. When I started the server and went to /dev/ folder I did not see either /sda or /hdb.
I only saw /hda for the master drive.
I am not sure about my next step.

The crashed server was running FC4 and the server I am trying to slave it on is running FC6. Any thoughts on how to move ahead here?

Thanks
ro

If the hard drive you are trying to recover was once a master, you may need to change jumpers' settings before plugging it as a slave.

try start with a linux install disc and typing
"linux rescue" at boot prompt.
Existing kernel and modules on the harddrve are configured for different hardware.

If I could have sex each time I reboot my server, I would definitely prefer Windoz over Linux!

hi,
thanks for the reply. I did change the jumper settings on the crashed drive. Also, when booting I cant even get to the boot prompt. The "kernel panic" seems to be almost instantaneous.

Hi richardko,

I said "try start with a linux install disc"

That way you will get to the the normal install prompt

something like


boot:


type "linux rescue"

yo will be taken in a very unsexy minimal shell environment where you will probably have to chroot to /mnt/sysimage to find your working linux install (if you are using redhat).

Once in there you can trouble shoot everything you need to.

thanks for the input QatQat

I tried using mount on another computer and I can read the files . I am trying to compress the html/ folder using :

tar xzvf html.tar html/

but I am getting error like this:

Cannot stat: Input/output error on some image files. Any idea what that error might be?

Run a fsck.extX on that filesystem.

That message usually appears on corrupted filesystems or unaccessible files.

You would create a tar.gz file with

tar zcf archive.tgz folder1/ folder2/

Perhaps that's part of the problem?

if you want to put both folders in the archive.

normally

tar -cvzf /dest_folder/tar.gz /folder_to_backup

I would also add the "v" verbose option and "p" to presrve users and groups permissions.

example

tar -cpvzf /dest_folder/tar.gz /folder_to_backup
