reiserfs support


recently installed VectorLinux on a reiserfs partition. But i am not able to mount this under RHEL. The kernel it seems is not compiled with reiserfs support. is there a solution without a kernel recompile? The previous post suggest a kernel recompile.
Additionally, are there any strong reasons i should go for reiserfs rather than ext3? i mean what are the pros and cons of having reiserfs rather than ext3. Anymore healthy options other than reiserfs and ext3?

uname -a

search your kernel src for:
reiserfs.o

if you find that, goto that directory and type:
insmod reiserfs.o

reiserfs support is not compiled as a module, or included in the kernel:

Code:
# grep -r "REISER" /usr/src/kernels/2.6.9-22.EL-x86_64/.config
# CONFIG_REISERFS_FS is not set
I think the primary reason for this is that reiserfs 3.x does not have extended attribute and quota support (without extra patches). EAs are required for SELinux, and quota support is a logical part of an enterprise distribution. Besides that, RedHat is a major supporter of ext3.

It is included with the kernel sources. The RHEL kernel does not have support for reiserfs, so you will have to recompile the kernel with reiserfs enabled. But I guess that you will lose support for RHEL.
