Bootscript
The following bootscript is only needed in a very specific situation, If you use an initramfs or some other early userspace to initialize lvm2 device nodes. This script only runs vgscan --mknodes and reports the status of the command on start. If you need this functionality, install the bootscript with the following command:
cat > /etc/rc.d/init.d/lvm2 << "EOF" #!/bin/bash ######################################################################## # Begin $rc_base/init.d/lvm2 # # Description : Creates lvm2 nodes that may have been created in an # early userspace. # # Authors : Joe Ciccone <jciccone@gmail.com> # # Version : 00.01 # # Notes : # ######################################################################## . /etc/sysconfig/rc . ${rc_functions} case "${1}" in start) boot_mesg "Running vgscan mknodes..." /sbin/vgscan --mknodes evaluate_retval ;; *) echo "Usage: ${0} {start}" exit 1 ;; esac # End $rc_base/init.d/lvm2 EOF chmod 751 /etc/rc.d/init.d/lvm2 ln -s ../init.d/lvm2 /etc/rc.d/rcsysinit.d/S16lvm2
