Hi there,

I got an old Redhat.  Not so sure about the version.  Perhaps Redhat 7 or 8.
The kernel is 2.4.20-31.9.sap

Now it won't boot up.   The booting process reached
.
.
Finding module dependencies:   [OK]
Checking filesystems
fsck.ext3Possibly non-existent or swap device?
:No such device or address while trying to open /dev/hdc1
/boot: clean, (some numbers)
/usr2: clean, (some numbers)
/usr: clean, (some numbers)
/dev/hda1: clean (some numbers)

                                                           [FAIL]

*** 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


The prompt is like (Repair Filesystem) 1#
                                (Repair Filesystem) 2#

I ran "fsck / -f -c -y" and it showed like

/dev/hda6  is mounted

Checking for bad blocks (read-only test): done
Pass 1: Check inodes, blocks, and sizes
Pass 2: Check directory structure
Pass 3: Check directory connectivity
Pass 4: Check reference counts
Pass 5: Check group summary information

I also ran "fsck /dev/hda1 -f -c -y" where /dev/hda1 may be /home

After that, "ls /home" did not show my home directory.

df comomand only showed
/dev/hda6


Any suggestion is appreciated.

hda1 is reported clean
hda2/3/4/5/6/7 as applicable need to be scanned.
when you are in the shell prompt #
run fdisk -l
to see what drives and partitions there are.

to access /home you need to mouint /dev/hda1 as /home or preferably as /mnt and then check what is in the partition.
fsck /dev/hda2 /dev/hda3
mount /dev/hda2 /mnt
ls /mnt
umount /mnt
mount /dev/hda3 /mnt
ls /mnt
etc.
one all the filesystem paritions are clean, you should be fine in booting the system.

However, by the sound of it, it might be that the hdb drive is the issue which is no longer functional.

the error with /dev/hdc1 is probably the cd-rom drive and can be ignored. you might want to comment this out of the /etc/fstab

run:
cat /etc/fstab
to see what should be mounted where.

missed that in the quick scan, usually a cdrom is not referenced as /dev/hdc1
/dev/hdc1 is/was likely a secondary drive in the system.
a cdrom is never mounted by /etc/fstab.
cd rom will often be referenced by its /dev/hdb durign the hardware scan.

Thank you, arnold and linuxninja.  

cat /etc/fstab shows that /home is under /dev/hdc1

fsck /dev/hdc1  shows:
fsck 1.32 (09-Nov-2002)
e2fsck 1.32 (09-Nov-2002)
modprobe: modprobe: Can't locate module block-major-22
fsck.ext3: No such devide or address while trying to open /dev/hdc1
Possibly non-existent or swap device?

What might be the issue?  Could it be hard drive problem?

Thanks.

Yes, the hdc drive may have died or may have gotten disconnect from power/data connection. Double check if it is connected, but does not work, the likely conclusion is that it is dead.
You could scan /var/log/messages to see whether there are references to when it died.
