Chapter 8. LVM 2 Boot
Time Scripts
For initrds, you should have:
dmsetup mknodes
vgscan --ignorelockingfailure
vgchange -ay --ignorelockingfailure
|
in the linuxrc to get the root LV activated before the
root volume is accessed. Most distros seem to have this setup in
their mkinitrd scripts now, and they also tend to have them in
rc.sysinit or equivilant, so all volumes get activated on bootup.
