problem about redhat 8.0


Hi guys,
I got a problem after I installed redhat 8.0.
After installation and the computer rebooted and chosen to load Linux, it gave me the error message:

mkrootdev: label / not found
Mounting root filesystem
mount: error 2 mounting ext3
pivotroot: pivot_root (/sysroot,/systroot/initrd) failed: 2
umount/ initrf/proc failed: 2
freeing unused kernel memory: 202k freed
kernel panic: no init found. Try passing init = option to kernel

Does anyone know how did it happen and how to solve it?

thanks alot,
mike
ps: I used the redhat auto partition

I've never had this problem, nor did I even know that these error messages existed...

But here goes:

One solution, follow all of the links:
http://www.redhat.com/mailing-lists/.../msg17545.html

A less likely solution:

And my google:

Not that this is much of an answer to your question, but it may help you figure out what is going on.

If you look at /etc/fstab you'll see something like this:

# cat /etc/fstab
LABEL=/ / ext3 defaults 1 1
/dev/sda1 /stuff ext3 defaults 1 2

You can describe which disk partitions mount as what filesystems either by pointing to their /dev/??? names or a LABEL. /dev/sda1 is the first partition of the first SCSI disk for instance. I do not know a lot about this LABEL business but assume it writes a bit of data on the partition (some kind of disk header area maybe) so that the _name_ of that partition can be known on subsequent reboots. In your case it's trying to mount root by finding a disk partition with this name and isn't finding it on any available partition.

The only times I've had to mess with this at all is after doing low-level manual things with disks and partitions. I've blown away and re-created partitions for one reason or another before and had to change fstab. In one case it point to LABEL=/stuff and I changed it to be /dev/sdb3 for instance.

A probable advantage to this LABEL business is if you install new disks or remove some the specific location format of /dev/sdX would get broken whereas the LABEL= format wouldn't.
