I have mounted an additional hard drive and all my files in /var are gone.

I added one more EBS hard drive in Amazon EC2. After mounting that drive my whole /var is gone.

I cannot even start Apache and also cannot use apt-get...

What should I do to restore it to be like before or at least make apt-get working?

It sounds like a) you accidentally mounted var to your EBS volume. Something like this:

mount /somevolume /var

you'll need to this:

umount /var

Or it is b) you accidentally unmounted var. Quickest way is to remount all (hopefully var still exists in fstab:

mount -a

We definitely need the steps you have done, but at this point, you really have nothing else to do short of trying to rebuild /var.

I guess that worked. :} – Rilindo Sep 13 '11 at 18:30
It helped me to get the idea :) – Jeong Woo Chang Sep 13 '11 at 18:35

You need to hire someone who knows about Unix & Linux to manage your server.

We can only help so much - there is a minimum level of understanding necessary that you do not appear to have.

Did you mount your new volume over the top of your existing /var ? If you unmount your new 'hard drive' does it reappear ?

I will try that – Jeong Woo Chang Sep 13 '11 at 17:15
It appears but apache does not work like before and what should I do to mount that extra drive and make everything works fine? – Jeong Woo Chang Sep 13 '11 at 17:22
What are you trying to achieve ? – Iain Sep 13 '11 at 17:25
@Jeong, you have to be really specific as to what you're trying to achieve. It's pretty obvious you want to add more storage... – Chris S Sep 13 '11 at 17:34
@Jeong - You can't even describe the issue in a meaningful way. You really should hire someone that knows what they are doing. – MDMarra Sep 13 '11 at 17:49
