Linux Red Hat 7.0 Fails at Checking Root File System


I have a Rad Hat 7.0 old Linux system that crashed due to power failure. On reboot the system goes to Checking Root File System and does 92.5% check and fails. Here are the error messages I get.

UNEXPECTED INCONSISTENCY:RUN FSCK Manually
Dropping to Shell:
Give Root Password for Maintenence or Cntrl-D for normal startup. Whien put the root password then I get tons of lines saying this:
REPAIR File System #1
REPAIR File System #2
REPAIR File System #3 and so on.
I don't know what to do at this point so I say yes and it goes in some wierd mode.

SO I ran fsck manually but I get an error
PARALLEIZING FSCK.

I can't fix the corrupted stuff for the system to reboot. THIS IS VITAL. Any ideas!!!!
Thanks!!!

Well, there are fsck options to repair things. First thing I'd do is to boot from CD/DVD, and drop into 'rescue' mode, and FSCK the disks from there. That way, things won't be mounted at all, and you'll be able to do a 'clean' fsck, and reboot.

Another option is to do what it says on the screen, and type "CNTRL-D" for normal startup. Once done, be sure to get a fresh backup, then do an orderly shutdown/restart, and try to fsck things again.

The last option is to blow away that ancient system, install something new, and restore your data. Which is probably the best thing to do anyway...use this as an opportunity to get current, and sidestep a bunch of issues.

Thanks, but the system was built by a guy who left the job and left no CD's for the system. So I will try few other things but I really need this system fixed till I can build another.

You don't need the original cd... just any repair/recovery cd or live cd really even. Try knoppix it typically works well.

Edit: Make sure you've got good backups first thing.

Exactly...ALWAYS make sure you've got good backups. And as rweaver said, you can use any distro. It doesn't even have to be a 'live' cd, either....most distros will have a 'rescue' option on the boot menu's, so download anything (Fedora Core, openSUSE, etc.), and boot from it.

Did you try the <CTRL-D>, as the system suggested?

Just FYI, on eg Centos/Fedora install media, you often just type

linux rescue

at the initial boot prompt; it's not on the menu.

I used fedora to run rescue linux and it asked me to enter IP address on the interfaces. This system boots up to the point checking root and now gives me the error, Filesystem has unsupported features. Get e newer esfsck is another message. I am really screwed.

Download a newer version. Use a live cd or rescue cd. Having fsck problems isn't typically a significant issue. There are a lot of ways around it.
