VFS:Can't find ext3 filesystem on dev dm-0

[hshzh359]

Hi:
ON centos5.0,I have comipled 2.6.28.7 kernel with reiserfs supported.
and then formated original /dev/VolGroup00/LogVol01 on "/" with reiserfs filesystem.
when I boot centos5.0.reported:
Volume group VolGroup00 found ...........

VFS:Can't find ext3 filesystem on dev dm-0
mount:error mounting /dev/root on /sysroot as ext3:invalid argument.
setuproot:error mounting /proc:no such file or directory
setuproot:error mount /sys:no such file or directory.
switchroot:mount failed:no such file or directory.

this is my /etc/fstab
/dev/Vg0/LogVol01 / reiserfs 1 1
LABEL=/boot1 /boot ext3 defaults 1 2
devpts /dev/pts devpts gid=5,mode=620 0 0
tmpfs /dev/shm tmpfs defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs defaults 0 0
LABEL=SWAP-sda9 swap swap defaults 0 0

Hi and Welcome !

/dev/Vg0/LogVol01 / ext3 reiserfs 1 1

You have formatted volume in Reiserfs filesystem. Remove ext3 from /etc/fstab file.

/dev/Vg0/LogVol01 / reiserfs defaults 1 1

sorry,I post wrong it's no ext3 before reiserfs.
but the results is the same.

VFS:Can't find ext3 filesystem on dev dm-0

Is it still throwing same error? Its trying to mount ext3 filesystem only. Something is wrong in /etc/fstab file.

After I compile kernel with reiserfs as (M). I backup my
/dev/Vg01/VolGroup00(/) and then I have formated /dev/Vg01/VolGroup00(/) as reiserfs and vim /etc/fstab:
change "/" mount as reiserfs. I restore back my "/" and reboot
.but reported the fault.
