I actually opened the Virtual Disk Image (.vdi) on
http://www.vmxray.com/ . I could see that despite my disk being of 100GB only ~65GB was being shown. All the stuff related ot the local user was not visible at all. After I restarted my VM, the OS gets stuck here ( http://i.stack.imgur.com/KVYxV.png). Even after trying the single user login it was stuck there. But the emergency mode worked alright.

Hi,
I am working on Centos6.6 on a VirtualBox on Windows Host. Today I started to have booting issues in the OS. It won't get past the loading screen. I checked and found that the files related to the user "cloudera" on the system were not accessible. Only the files related to root were accessible. This is why I was am not able to do a single user login but an emergency login was possible. This is just a guess. This all happened due to some update in the Virtual Machine that I use to run CentOS.
Is there any workaround for this issue?
Thanks and regards, Animesh Pandey
I wish you could provide more info.
How can you determine that inaccessibility to a user's files will prevent centos from taking you all the way to the login (or welcome) screen?
I think something else is going on and my guess is that the centos files themselves have been corruped. Can you re-install centos ?
Please do not top-post.
I am having trouble following your terminology. Emergency model? On my centos installation, there is no "Emergency ...." to select from the list of kernels to boot.
Also, when you say "worked alright" do you mean that you were able to access what you thought was missing? Can you go to full multiuser?
Sorry for top posting.
Let me give you a clearer idea.
- My regular boot freezes after loading is completed.
- I read on the internet that sometimes due to an update in VirtualBox,
this error might occur. To rectify it, I must re-install VirtualBox's Guest Additions. For this, I require booting in a Single User Mode. 3. For that, I followed the correct steps as given here (
https://www.centos.org/docs/5/html/Installation_Guide-en-US/s1-rescuemode-bo... ). But still the system froze on that same point. 4. Then I read about an Emergency mode which is even lower level to that of Single User mode. I was able to log in and see the files that I created/modified as root. I could not see any file/folder that related the local user "cloudera" on which I used to work. This is where I thought of seeing the contents of the Image using vmxray.com and found that a large part of the dick is not visible. This part contains that files related to "cloudera". I felt as if any information related to "cloudera" user has been lost.
I basically need to access files that I made as "cloudera" on CENTOS and if possible re-install the Guest Additions that ma solve this issue. But for this I need to be able to boot as a Single User.
I assume you are using a virtual drive, which is a file on the host machine (You said windows??? ). If you can somehow use a tool to dump that disk image to a real hard drive (for example using dd ), and connect the hard drive a a working linux computer to run fsck on it to see what it will find. I assume you have no backup of your drive???
CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Yes it is windows. By dumping a disk image do you mean a VDI (VirtualBox Disk Image). These are files that are used by VirtualBox for booting. I have a copy of that as well. Can Gparted be used for connecting that VDI?
