[linux-lvm] RH 6.2 kernel problem with 0.8i

	I figured out my problem.  It's the RAID patches that RH adds.

	RH adds a LOT of patches to the stock kernel.  Someone suggested
grabbing a stock kernel and using that, but a lot of the RH patches are
ones I really want, and I don't want to sift through them carefully
figuring out which ones.

	So, I grabbed the kernel source RPM, used rpm2cpio on it,
unpacked the cpio, and then used patch -R (what a wonderful tool) to
reverse the patches I didn't want out of the kernel source tree RH

	After that, the LVM patches applied just fine.  I only wanted
RAID0 anyway, and LVM does that just fine by itself.  :-)

	It works beautifully!

	The only thing I could ask for (and it is something that would
be complicated to dp) is to allow the root filesystem to be a logical

	A graphical (say tk or Python based) manager might be nice to,
but there are already several people working on that.

	Thanks a LOT for providing such a neat, useful tool.  Virtual
memory for hard drives.  It's great!

	One question...

	Is the warning about moving the physical extents of a mounted
logical volume based on hard evidence, or uneasiness?

	As I recall from Hans's talk, there shouldn't be any problem.  I
think I remember that the blocks are locked from being read or written
to while they're being moved.  And besides, the buffer cache entries
point at the logical volume anyway.
