Description Hans-Peter Auer 2002-10-25 07:14:56 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT)

Description of problem:
When booting a pc with two harddrives (hda, hdc) with installed RedHat-Linux 
(>7.0) it is possible to format /boot without enny warnings.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.install only one harddrive in the pc as hda, and install rh on it
with three partitions (hda1=/boot, hda2=/, hda3=swap)
2.process with the secound harddrive exactly at the same way like described at 
(1.)
3.install both harddrives in the pc as hda and hdc
4.boot the system normaly
5.execute mount to show the mounted filesystem
6.makefs.ext3 /dev/hda1	

Actual Results:  5.mount sayes that "/boot" ist mounted from hdc1 and "/" from 
hdc2
but in real the right mount devs are mounted (hda1 and hda2)
6./dev/hda1 will be formatet without ANY warning !!!

Expected Results:  5.mount must show the right mountpoints
6.makefs.ext3 must stop with the message that it could not format a mounted 
filesystem

Additional info:

i think the problem is comming from the way rh-linux scanns for ext2-partiton-
labels and the way mount/kernle interprets the lable/device relation

Comment 1 Elliot Lee 2002-10-29 11:50:02 UTC
If mount says that /boot is coming from /dev/hdc1, I see no reason to disbelieve it.

If you want to specify a particular device to mount, edit fstab to reference that device 
instead of the label. Mount by label can't be expected to know which one you "mean" to be 
mounted :)
