I've actually looked through the howto but am still unable to determine
how to actually create a lvm system. I've recompiled my kernel to
have the devive mapper as a module and modprobe'ed it.
When I try to do vgscan it states that the kernel modules are not loaded.
I
don't remember how I did this with RH9 to make it work, but I remember
I played a bit whth modprobe, the LVM tools and the man pages :)
Please help.

I did install FC1 with Software Raid 5 and LVM on top of it, but doing so on less
than three physical disks results to up to 5 times slower transfer (because of the
raid). If you have 3 disks read speed increases and the write speed is almost the
same. Using ReiserFS I was able to resize 61G LV to 64G LV without errors. With
ext3 it worked, but fsck.ext3 had a lot of work to do (the partition was ~50G full).
I hope one day online resize will work with bouth and reiserfs will get more stable
with acl and SELinux support.

ps: putting the /boot partiton ouside the LVM worked fine for me.
