[linux-lvm] Startup/Shutdown scripts for RH6.2?

[linux-lvm] Startup/Shutdown scripts for RH6.2?

[Jeffrey B Layton]

Hello,

   Of course I'm a newbie :) I'm been experimenting with LVM
prior to a production installation. I've got everything working
pretty well with a RH6.2 installation and a custom kernel.
However, I'm a bit stuck on the startup/shutdown scripts. I've
tried a couple of things after searching the archives, but nothing
seems to work (i.e. the volume groups are not found and then
mount complains very loudly). Any suggestions/tips/code?

TIA,

Jeff Layton

I had the same problem too at one time. But I added appended script in
/etc/rc.d/rc.sysinit right after the RAID initialization and right before
the file system starts getting checked (before _RUN_QUOTACHECK). I added
the stop script in /etc/init.d/halt.
I found this script in the group archive.

## LVM
#scan for VGs and create /dev entries.
if [ -x /sbin/vgscan -a -d /proc/lvm ]; then
       action "LVM: Scanning for Volume Groups" /sbin/vgscan
fi
#activate all VGs
if [ -x /sbin/vgchange -a -e /proc/lvm ]; then
       action "LVM: Activating Volume Groups" /sbin/vgchange -ay
fi
## End LVM

Hope this helps

This will only work (AFAICS) when LVM is compiled into the kernel, because
/proc/lvm will not exist if it is a module.  My startup has this first:

[ ! -e /proc/lvm ] && (modprobe lvm || modprobe lvm_mod) 2> /dev/null

Cheers, Andreas
