   Hello folks,

   I CVS'd down the source to your XFS 2.4.1 kernel last night and built a
kernel and tools under RH-6.2 for a RAID that I'm setting up to export
home directories. The system isn't production -- yet -- so I'm willing to
experiment for the moment. However, I've run into a few problems:

a) The kernel build environment demands kgcc. Simple fix.

b) The tools build fails at the end with an error to the effect that one
needs linux-2.4.1.tar.bz2 in <build>/SOURCES ... adding the tarball
doesn't fix the error. Fortunately, it appears that critical tools such as
mkfs.xfs et all are already installed by that point.

c) With modutils-2.4.2 installed I'm getting:

[root@ctpraid1 /etc]# insmod autofs

root@ctpraid1 /etc]# rpm -qa | grep modutils
modutils-2.4.2-1
[root@ctpraid1 /etc]#

Module and versioning support is compiled into the kernel.

   Finally, a question: I know that reiserfs has had problems in the past
with file corruption on NFS exported volumes. Should I expect similar
issues with XFS? (Hope not!).

Thanks,
