reiserfs support

logicalfuzz · 11-17-2005, 10:18 AM

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?

try:
modprobe reiserfs

if that doesn't work, what is the output of:
uname -a

Code:

[root@saturn ~]# modprobe reiserfs
FATAL: Module reiserfs not found.
[root@saturn ~]# uname -a
Linux saturn 2.6.9-5.EL #1 Wed Jan 5 19:22:18 EST 2005 i686 i686 i386 GNU/Linux
[root@saturn ~]#

dmesg
that should tell us if reiserfs support is loaded

Code:

dmesg | grep reiserfs

returns nothing. You want me to post the complete output of dmesg?

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.

Dear All,
I am getting the error like " mount: fs type reiserfs not supported by kernel" when mounting the fs.
From forum info i understand that we need to add above said module into kernel.But from i download this module or where can i get this module.
Waiting for +ve reply.

My server details are as follows :
Os : Redhat AS -4 or RHEL -4

Thanks,
Shrinivas.

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.
