kernel panic & ext2 filesystem

kernel panic & ext2 filesystem

[Luca Ferrari]

Hi,
I'm still fighting against kernel 2.6.4. Now I found a strange behavior, that 
cannot explain to myself. I've got all my partitions formatted with reiserfs, 
and in particular:

luca@lucaSassuolo:~> mount
/dev/hda2 on / type reiserfs (rw)

that means root partition /dev/hda2 is reiserfs. Now I've unchecked ext2 and 
ext3 support in the filesystem options, leaving support for reiserfs directly 
in the kernel (i.e., not as module):

lucaSassuolo:/usr/src/linux # grep REISER .config
CONFIG_REISERFS_FS=y
# CONFIG_REISERFS_CHECK is not set
CONFIG_REISERFS_PROC_INFO=y

but at the reboot I got a kernel panic, since it was unable to mount /dev/hda2 
as root. I've re-checked the support (not as module) for ext2 and ext3 and 
the system starts.
Why should I support ext2,3 if all my partitions are reiserfs? Can anybody 
explain me this?

Thanks,
Luca

What is the exact kernel output?
What looks your /etc/fstab like?

Luca,
   If you use initrd, its' filesystem is ext2.

In fact I suppose it it this the problem, but I thought that enabling initrd 
support in kernel suffices. However thanks for the help.

I think that what Jeff means is that if you're using an initrd that you
didn't make yourself, it will be using an ext2 filesystem.

As far as I know, though, there is no reason you couldn't build your own
to use whatever you want.
