Description Arenas Belon, Carlo Marcelo 2001-04-04 23:24:44 UTC 
on rc.sysinit the lvm-mod is started but there is no corresponding stop
script.

as explained on lvm documentation, a:"vgchange -a n" call should be placed
on the shutdown script after dismounting all filesystems.

check forced on /usr after all.

Comment 4 Arenas Belon, Carlo Marcelo 2001-05-03 11:54:41 UTC 
updated patch for RH7.1 gold (just a change on the directory name anyway).

calling vgchange -a n on halt is not really needed now as no metadata is saved
on the vg, but this could change soon and this is documented as a need for lvm
installations

Comment 6 Bill Nottingham 2003-01-13 22:17:59 UTC 
The kernel people say that this is not needed.
Comment 7 Arenas Belon, Carlo Marcelo 2003-01-13 23:57:02 UTC 
it is not needed (that is why it was filled as an enhancement with low 
priority), but as you can read on LVM/{%version}/INSTALL (point 9) it is 
required as part of the LVM installation.

it does nothing when called because once you deactivate an LVM volume the only 
resource that could be freed is the LVM module and no data gets saved, but this 
could change on the future.

this patch is not recommended on systems that have the root filesystem on LVM 
though
