I have a system running FC5.
Over the weekend the system froze.
I rebooted and during the boot O receive the message
Error 16 Inconsistent File System Structure

I have booted with a rescue disk and run fsck, which claims all is well.
I search linuxquestions.org and found a few things tpo try like reinstalling the grub, but nothing has worked.

Is there anything I can do to fix this boot problem?

What type is your file system? What is the output of ?

fdisk -l /dev/sda

Disk /dev/sda: 18.2 GB, 18210036736 bytes
255 heads, 63 sectors/track, 2213 cylinders

grub.conf

initrd /initrd-2.6.17-1.2139_FC5smp.img

Okay, that means GRUB expects your "/" on the first partition (and quite small). Is that so? Did you change something in "root=LABEL=/1" (looks funny to me but I don't use labels much)?

You didn't tell with what file system you formatted the drive...

grub.conf looks like this now. I don't know where the '1' came form.

default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu

kernel /vmlinuz-2.6.16-1.2122_FC5smp ro root=LABEL=/ rhgb quiet
initrd /initrd-2.6.16-1.2122_FC5smp.img

Since fdisk is not telling me the format type, how can I find it?

I did not originally configure this system.

Do you still have the install CDs? You might just pop in the first one, usually the distros detect an existing OS and offer to repair any damage, including damage to the boot loader.

"fdisk" told you the file system type: 82 (linux) meaning ext2 or ext3. Hum. Out of my depth here...

Well, the GRUB manual says:

"16 : Inconsistent filesystem structure
This error is returned by the filesystem code to denote an internal error caused by the sanity checks of the filesystem structure on disk not matching what it expects. This is usually caused by a corrupt filesystem or bugs in the code handling it in GRUB."

With which parameters did you run fschk?

I am facing the same issue for RHEL5 and i am not able to switch to Maintenance mode also.
My server is not booting. Can anyone suggest, what to do in this case.

Good luck!

the very dead and very unsupported Fedora core5
is NOT the same as the soon to be End Of Life RHEL5.11
( you are using 5.11 !!! it is the ONLY version of 5 still supported by redhat)

and seeing as this is RHEL5 you do have the REQUIRED support contract ! right ?

contact redhat customer service

as to booting
just use the normal everyday
SINGLE USER boot

put a blank space and a 1 at the end of the grub0.98 kernel line
