I've had the same issue with NTFS.

To get around it, I set up a small NTFS(in your case xfs) partition at install time.

Doing this insures the necessary kernel module is installed and compiled into the kernel.

Now you need to do this and re-compile the kernel after the fact.

There is no kernel xfs support with RHEL4 anymore due to 4KSTACK issues.

You need to rebuild a kernel with 8KSTACKS and enable xfs.

and what abt the jfs issue ? I mean what should i do ?


# rpm -q jfsutils
jfsutils-1.1.7-1


# mkfs -t jfs /dev/hdc3
mkfs.jfs version 1.1.7, 22-Jul-2004

You must re-kompile the kernel with jfs support, since RedHat decided not to include the modules with the stock kernels.

>>
# cd /usr/src/kernels/2.6.9-11.EL-smp-i686/
# grep -i jfs .config
# CONFIG_JFS_FS is not set
# grep -i xfs .config
# CONFIG_XFS_FS is not set
CONFIG_VXFS_FS=m
#

Like Axel Thimm pointed out, xfs is not available at all in the kernel.

[Jarle Bjorgeengen]

What a liar I am, I just showed that xfs indeed is available to configure in.

So re-compile kernel with xfs and jfs support included should do the trick .

Be aware of the error mentioned by Axel though.

Also be aware that RedHat does not support recompiled kernels.
