As I have mentioned in my previous email, is there a way to recover or bring back to life a crashed CentOS OS after doing a Hard Driver repartition or resizing?
Thanks.

CHRIS

Actually, I am not sure if we have a backup, because honestly, I am not that very much familiar with CentOS. We use it for our mail sever for zimbra and other web servers but after setting it up, as long it is working just fine we don’t do any other thing.
Does it have an automatic backup system? And if it does, how can we use it to restore it back?
Thanks.

there is no such as automatic backup.
if you are not familiar with system, you should hire consult and fast to minimize damages.
doing low level disk level operations to system.. is very.. dangerous without knowledge

Not out of the box. If the drive is not usable in its current state, and you do not have backups, you may need to bring it to a professional drive recovery shop.

Hi,
For fuller information that may allow someone too help.
What version of CentOS?
LVM or standard partitioning?
Method (commands etc.) for resize that ultimately failed?

There is software out there which will rebuild. It is advanced level, so I
would concur with the others to take it to a professional data recovery service. Most importantly at this moment is to remove the hard drive, or at least shut down the server to minimize the read/write to the disk. The more writes done the less likely recovery will be possible. Also, know whether you just want to recover data or rebuild the OS structure. Former is easier/cheaper than the latter in most cases.

apologies on the top posting.
Possibly. It depends on how the disk was previously arranged, what filesystems are in use, and exactly what you did to get to the current state.
If the data is really important, professional data recovery would be appropriate. A mailing list isn’t a great place to carry on such a conversation. A more appropriate venue would be http://www.linuxquestions.org .
I recommend REAR next time, part of CentOS. Wonderful utility.
