Multi linux redhat + SuSE ,no reisfer FS in redhat linux?


Multi linux redhat + SuSE ,no reisfer FS in redhat linux?

Now I have installed Multi linux OS on my PC,Redhat and SuSE
the boodloader is redhat GRUB.and the FS in redhat is Ext3 and the SuSE is reisfer

Though they all have been in the grub.cof, but the Suse can not be loaded from the redhat grub.

[root@redhat1 grub]# mount /dev/sda6 /mnt/cdrom/
mount: fs type reiserfs not supported by kernel

fdisk -l output:
/dev/sda1 1 65 522081 83 Linux
/dev/sda2 1913 9725 62757922+ f Win95 Ext'd (LBA)
/dev/sda3 9726 9726 8032+ 7f Unknown
/dev/sda4 66 1912 14836027+ 83 Linux
/dev/sda5 4463 4724 2104483+ 82 Linux swap
/dev/sda6 * 4725 7335 20972826 83 Linux
/dev/sda7 1913 2043 1052194+ 82 Linux swap

The grub.cf output:
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
title Red Hat Enterprise Linux ES (2.4.21-15.EL)
root (hd0,0)
kernel /vmlinuz-2.4.21-15.EL ro root=LABEL=/
initrd /initrd-2.4.21-15.EL.img
title Red Hat Enterprise Linux ES (2.4.21-9.ELsmp)
root (hd0,0)
kernel /vmlinuz-2.4.21-9.ELsmp ro root=LABEL=/
initrd /initrd-2.4.21-9.ELsmp.img
title Red Hat Enterprise Linux ES-up (2.4.21-9.EL)
root (hd0,0)
kernel /vmlinuz-2.4.21-9.EL ro root=LABEL=/
initrd /initrd-2.4.21-9.EL.img
title suse
rootnoverify (hd0,5)
chainloader +1


I wonder know how can I boot the reisfer FS from redhat?

thx alot

Ray

Change your Suse entry to something like,

title Suse
root (hd0,5)
kernel (hd0,5)/boot/vmlinuz root=/dev/hda6 vga=788
initrd (hd0,5)/boot/initrd.img

Make sure the kernel and initrd.img lines correspond to whats on your system or else it wont boot. This should boot Suse and shouldn't give you the reiserfs error. RHEL 3 is based on Fedora Core (1 or 2 I am not sure which) and earlier versions didn't support reiserfs. Fedora Core 3 does, so I assume RHEL 4 does as well.

I think your mean is to rewrite the MBR by booting from SuSE install CD?

and then change the grub.conf in SuSE ?
Would like give me some more detail process?

all the files have been in the correct directory,but when I choose the SuSE ,the system said that the FILE NOT FOUND,

is it depent on the grub.conf in SuSE?
because this file is not in the /boot/grub/ but in the /etc/

Both of the /boot/ and /root are all in the same partition /dev/sda6(in suse it is /dev/hdc6,I don`t know why it is different.)

I've never worked with scsi disks so maybe others can help you out. Also do a search on google for grub and scsi disks.

the sda is not a real scsi disk ,they just be named in the /boot/device.map ,acturely it is a IDE drive.


Would you like tell me how to re-install the grub?
I want to boot up the SuSE in rescue model by Install CD.

is it corrected?
