can't mount root
 

Hi All,
My Redhat 7.3 is fail to boot up and need me to run fsck when booting up.
I try "fsck -t ext3 -y /dev/hda1" and result:

fsck.ext3:e2fsck_read_bitmaps:illegal bitmap block(s) for /

What should i do more?


RMK: I havn't any backup and the data are so IMPORTANT.

Thank you all

how are you running fsck if your computer isnt booting?

you probably have a corrupt boot sector and need to throw the drive away.

Hm...I'm not entirely sure what's going on - what do you mean when you say that your computer won't boot. As AutOPSY said, how are you running fsck?

If you want to attempt a rescue of your data, you could try putting the hard drive into another computer as a slave drive or something, then mounting it using that - that way, it'll read the data, and not try and boot it.

Please post back with some more info - then we'll try and diagnose the problem.

I have try to use other Redhat hard disk to boot up.The broken Hard disk is slave.I try boot,but system need me run fsck again.I can't get in system to mount the Slave Hard disk

Thanks a lot

Woa...I'm not entirely sure what you're saying. Are you saying that you have *two* broken installs? Please clarify.

I'm sorry.I explain more about my status.


My Redhat 7.3 is a Maxtor 80GB hard disk and partation "/" is 78GB and
Swap is 2GB.
Now it is can't mount. I have tried use Floppy or CD to boot up and run fsck.The result is "/" also can't fix and fsck show last line message:
'fsck.ext3:e2fsck_read_bitmaps: illegal bitmap block(s) for /'

After that, I try use another linux hard disk(Redhat 8.0, 15GB HDD) to boot.
And maxtor set to slave.
When Redhat 8 is starting, system will need me run fsck Manually.I can't success to boot into redhat 8.
So I try to run fsck (fsck -t ext3 -y -p /dev/hdc1) to fix maxtor again.But the result same as before.

What thing should I do? or how can I boot into redhat 8 to mount the old_HDD?

Thank you all
