lvm2 question

[Neal Becker]

This is after a clean install of FC2Test1:

/sbin/vgdisplay
vgdisplay -- ERROR: "/etc/lvmtab" doesn't exist; please run vgscan

[root@rpppc1 nbecker]# /sbin/vgscan
vgscan -- LVM driver/module not loaded?

I'm just trying to display properties of my lvms.

i see this if i try to run vgdisplay as a non-root user.  which leads me 
to ask, is there any reason non-root users *shouldn't* be allowed to run 
that command?  just curious (he writes, knowing that this really has 
nothing to do with fedora test.)

case.

This binary requires the LVM1 drivers.  kernel 2.6 has only LVM2, with
LVM1 compatibility, so you need the lvm2-compatible userland program,
named lvm.  Run `lvm vgscan' and it should work.

[Aleksander Demko]

Try /sbin/lvm vgscan --mknodes
then perhaps:
/sbin/lvm vgchange -a y

I'm guessing the super lvm binary is for LVM2 (which is what
2.6/FC2 uses)... All the old non/sbin/lvm binaries are LVM1.
