CentOS

Hi
I have a issue with centos 6.6 version virtual machine on Hyper-V. When reboot pop-ups showing Cannot update ICEauthory /var/lib/gdm/. ICEauthory. This virtual machine has 1.5 million data of patients of Medical clinic. I have tried all possible tricks to recover but unfortunately I cannot recover it. When machine booting pressed e and added to kernel line single space also but no way to recover it. Can someone please help???

What happens if you remove "rhgb quiet" and add "1" to the kernel line?
Never used hyperv, but on a physical machine you can press crtl+alt+F2
to get cli. And I'm sure you know C6.6 is severely outdated with six
years accumulated security problems?

!!

But you're running an operating system that a) hasn't been patched since *2014*? And one that goes End of Life tomorrow? Do you know how dangerous that is?

I hope you mean added a space and the word "single" because that is the correct way to boot in single user mode.

Anyway, if all you get is the popup about /var/lib/gdm/.ICEAuthority then that's just the GUI. Your machine is probably up and running and you should try to connect to it via ssh and see if you can get on that way.

Red Hat have a knowledge base article https://access.redhat.com/solutions/65886 about this.

Root Cause
Files and directories under /var/lib/gdm are owned by root, it should be owned by gdm user.

Resolution

Correct the ownership of /var/lib/gdm and it's subdirectories with the following command:
Raw

# chown -Rv gdm:gdm /var/lib/gdm/.[^.]\*

I have tried to connect via ssh but port is closed. This machine was made another system administrator. He connected only via ssh. The day before yesterday back end developer restarted machine and whole website stopped work. I want to migrate data to centos 8 physical machine. If can someone help me to recover it we will pay and we will give remote access to our server

Be smart, don't just pick anyone.

First try the advice above to see if you can get access to console through hyperv.

Try switching consoles using ctrl-alt-f2 or whatever the key combination is on hyper-v to pass through the equivalent (on vbox it's $hostkey-F2).

On WS2012R2 you can open console like this:
- open Hyper-V Manager
- rightclick on VM and select Connect
And it looks like crtl+alt+F2 works.

I don't think that I can quite get over my shock that you have data on 1.5 million patients on an insecure machine. Are you sure that you are not breaking any laws?

You should turn off the machine, save the data and start from scratch. Whatever you do, the machine will be unsupported. There will be no further updates. There is simply no point trying to recover the machine. You should focus on recovering the data.

Perhaps you need to attach a CentOS DVD, boot from that and immediately copy the data somewhere secure.
