I have RedHat 6.1 installed and has been running normally. Out of the blue, it comes up with an error (listed at the end of this message). I am then prompted for the root password. It will then drop to a command line. X will not boot. I am a newbie (thus please give a fairly clear answer). Here is the boot sequence and error:

What happens after you login with root? Are there any errors? From the looks of it, you might have a problem iwth your filesystem. If you have access to the filesystem from logging in as root, this is when you want to check log files. It says checking root filesystem failed, You didn't happen to shutdown improperly, like just turn the machine off or lose power. If so, could have destroyed everything and you need to just reinstall. It could get to complicated trying to fix that if your new to Linux. You mention X isn't working, I wouldn't worry about that yet with this error your getting.
This has happened to me one time, I couldn't determined what happened, I think my father in law tried to access my machine and he knows nothing of Linux so it started boting into Linux, he has no password so he turned it off. But besides that, I ended up reinstalling since I didn't have to many imprtant things that I would lose.

Let us know.

When I login as root, it gives me a command line. No visable errors are apparent. Usual commands function normaly (excluding X). The root filesystem is mounted. When I run linuxconf, it shows that no other filesystems are mounted (but they will mount manually). What logs would I check to see what happened?

Thanks for the help.

Unhappy sounds familliar...

i probably don't know what i'm talking about, but i got an error like that before, and it turned out that my hd had died.

x might not load because the disk is not functioning correctly or has bad sectors(sometimes power surges or incorrect shut-downs cause this.)

try running other programs off the disk to see if they can work

i hope you fix the problem...goodluck.

Exclamation

All data is still there. I can run X if I (at the command) type

shutdown -f now

, then I get a shell, then I exit that shell.
X then starts up after that exit.

Doesn't make any sense to me.

Rescue environment

You need to run a filesystem check, but you need to do it with the volume unmounted.

I don't remember if Redhat v6.1 had a rescue environment. Boot to the CD and see if there is a "rescue" option at the first "boot:" prompt.

If it doesn't, then you can get Tom's RBT from http://www.toms.net/rb

In any event, you can boot and root with either method and then you will be able to run a filesystem check on the unmounted partition.

Example: e2fsck /dev/hdb5

(you might be able to do this from the maintenance prompt that you are getting too, but I doubt it)

It also appears that your system maybe looking for a RAMDISK and is unable to locate it. Are you by any chance using Software Raid?
