System Fails to Start

Post by MikeZ1978 » 2019/09/15 21:12:15

Hello All,

I rebooted my webserver today (running Centos 6.10) and as it reboots, it reports:

Code: Select all

Welcome to CentOS
Starting udev:
Setting hostname [my hostname]
Run MD devices:
Checking filesystems
/dev/sda3: clean, 46262/13918208 files, 14796413/55644416 blocks

*** An error occurred during the file system check.
*** Dropping you to a shell; the system will reboot
*** when you leave the shell.
Give root password for maintenance
(or type Control-D to continue): _
When I log in (I'm able to get to the command line,) VERY few commands are available to me.

Typing the command FSCK doesn't work, and gives me the response:

Code: Select all

bash: fsck: No such file or directory
Can anyone help me recover from this? Am I dead in the water, or is it still possible for me to revive this computer?

Thanks -

- Mike

fsck.ext4: Unable to resolve 'UUID=006e80a1-792d-4aa0-93a7-fa81c226cb27'
If it were mine, I'd be looking into what happened to that ext4 drive. For instance, did the UUID change? Did the drive fail? For some reason your system can't resolve that UUID number to a drive.

EDIT:

I'd login as root and 'chroot' or what it suggests
I'd use vi to edit /etc/fstab & comment out that line (don't remove it!) and save the change
The machine ought to be able to reboot and run now

- from there, you can investigate the drive.

Hi Lightman,

Thanks. I think the drive may have died. (It's internal, so it's not a question of removal.)

So I should be able to log into "root" by typing "chroot"? (The management account is VERY limited - it doesn't even maintain the path statement.)

And, from what I've seen, the drives are write only in this account.

I'll try your suggestion when I get back to the local term.

Thanks again -

- Mike

Sorry - login as root by supplying the root password at that prompt. If you don't have the root password, then there's no sense in proceeding further as far as I know. An alternative may be using 'live' media in the attempt to edit /etc/fstab (?) Maybe someone else here with more experience can help.

Also, most internal drives are replaceable.
