If it hasn't already been mentioned, perhaps you could suggest to
Heinz:

The ability to do raid, specifically raid1, with LVM should be
included if linux LVM is to mimic the LVM used on HPUX; perhaps
merging linux md tools/drivers with lvm tools/drivers?
The ability to create > 256 items (lv's, vg's, etc), perhaps by using
multiple majors?
Storing lvm information for each group in entirety on each group's
pv's headers as such:
	vgtest members: /dev/hda /dev/hdb /dev/hdc
	vgtest lv's: testlv thislv thatlv
	vgtest lv pe boundaries: testlv ...
				thislv ...
				thatlv ...
	ad nauseum so that the kernel and the /etc files are not the only
authoritative sources of lvm structures (3 sources allows for a
quorum)
Storing lvm native host information so that vgs could be
exported/imported from host to host in MI scsi configs
Deeper integration into the kernel such that / can be an lv without
an initrd (this may already exist?)
[Deeper] integration into bootloaders such as lilo, grub, etc so one
can boot from a secondary (ie mirror) boot device, potentially
automatically.
	(ie primary boot device: /dev/vg00/root which is raid1 consisting of
/dev/hda and /dev/hdb... if /dev/hda becomes inaccessible, boot from
/dev/hdb half of /dev/vg00/root automatically)

Again, these things may already be in the TODO list, wish lists,
whatever... but in case someone hasn't thought of them, these are a
few ideas my colleagues and I have had regarding linux LVM.

Thanks,
