unable to fsck

Mike_866 — Tue, 04 Jan 2005 04:03:52 GMT

Hi there , just recently , I changed my Linux server's root password . After a reboot , i was unable to login with the same password again . It can't even take any previous password also . I have tried logging in as Linux single , to change the password .But the system is asking for root password again , for a maintenance . During the boot process , it says your /var/ folder is having problem and run fsck manually . Do the fsck , I typed the root password , but unable to accept any password , I am stuck there .

During the boot process , there was a message saying " change root = old root has d_count=1 "
Any help is appeciated .

After booting from RESCUE mode you will get a shell prompt. In the shell prompt enter "chroot /mnt/sysimage" and next enter "passwd". This will ask for your new password. Enter new password.

Exit from the shell by entering "exit". Eject your CD1 now. Now booting starts from hard drive.

Regards,
Sergejs

Thanks for your reply , I did that it says
" chroot failed : no such file or directory " . I checked the mnt folder , there's source and runtime files

I tried chroot /mnt/runtime , the same result comes out .

try to run fsck /var in form:
fsck /dev/hda?

where /dev/hda? is the actual /var partition...

As a workaround I can suggest you to remove the hard drive from this machine and to connect it as second hard drive on another machine with Linux installed on it.
Then you definitely should be able to fsck it's partitions from anothe Linux system.

unless you have virus on your fedora server, it shouldn't cause any problems.
In fact sometimes I do it at my work.

Did you tried with a "live CD" like Gentoo Live CD, you are able to login as root in Gentoo and do any fsck of any partition.

Hi Alex , I can't do from another Fedora server, because my Linux server is using SCSI controller and my Fedora server is running under IDE . I can't do an fsck by swapping the hard disk .

Hi cuitlahuac , thanks for replying .
I tried the Gentoo software , but after donwloaded into my CD , the CD is not bootable . I think because my CD-writer is unable to " Record CD from CD Image". try to save the ISO file . My CD software is unable to do that .
Any other options

But allmost all can do that,

Wich software are you using?

in console commands

1 As root, type:

cdrecord -scanbus

... in order to determine the device. It will be something like '0,0,0'

2 Next type:

cdrecord -dummy dev=0,0,0 sample.iso

... in order to perform a test run. Remove the -dummy flag (but keep -dev) to do it for real.
