Failed booting after the latest updating

Latest response

Hello,

I am using Red Hat linux workstation 7.0. Unfortunately, after the last updating done yesterday (24-06-2015), the system failed to log-in after reading the file systems. It just hang up after reading the file systems. A forced switching off showing the message ' Cannot finalize remaining file systems and devices, giving up'. Please help me to figure out what happened with the latest updating.

Many thanks in advance

Regards
Aneesh

Hello Aneesh,

Can you boot with an old kernel, or do you get the same issue?

Kind regards,

Thanks for the reply. By 'old kernel, do you mean the 'rescue' kernel ?. How to find the old kernel? I am not much familiar with linux systems.

Hello Aneesh,

In the boot menu: How many entries do you see?

2 or more?

If only 2 try the rescue kernel.
If more try one with a lower number sequence then the default line.

Also tell us, what updates did you apply? All or a subset?

Kind regards,

Jan Gerrit

Hello Jan,

Thanks for the reply. I have four entries in the boot menu, including rescue one and the fifth one is ' recovery mode, erase all data'. Now I will try with the lowest numbered one, though my try with second kernal also end up with same result. I have updated all together, after the update message was popup.

Hello Jan

I have tried with all the lower number kernel, but none succeeded. Now the only option left is rescue kernel. Is it safe to go with rescue kernel and can I go with it? What steps should I follow if the rescue kernel is working?

many thanks
Aneesh

Hello Aneesh,

The rescue kernel is safe.
If that works, check /var/log/messages for strange messages.

Do you have a support subscription?
For setting up booting in runlevel 1 in RHEL 7, is still hard to explain for me.

Kind regards,

Hello,
The rescue mode is working. The command 'journalctl -xb' shows the following few messages highlighted in red font colour.

Failed to mount NFSD configuration file systems
mount: unknown filesystem type 'ext4'
mount: unknown filesystem type 'vfat'

Yes. I do have a support subscription.

Please help me to figure out the issue. It really painful to see that updating with RHEL provided libraries showing such issues, though RHEL know for their stable libraries.

Yes, I do have support subscription.

Thanks

Hello,
Also I can say from my yum.log that the last update has updated the kernel.

Thanks

Hello,
Adding to the loop, the 'journalctl -xb' message also shows,

mount: unknown filesystem type 'vfat'
failed to mount /boot/efi

Many thanks in advance

My KVM guest does not have /boot/efi directory at all, so I do not know if the it is a must.

I guess it looks more like a filesystem driver issue.

What filesystems do you use for / and /boot?

Thanks for the reply.

My / and /boot are xfs filesystem. Addtitionally, I can see /boot/efi also in /etc/fstab, which is vfat fiel system.

hope this help

Adding to it, all my harddisk partions have ext4 filesystem.

Thanks
