[gentoo-user] root on EVMS, evms_activate, checkroot, rw/ro mount, gah

[Michael [Plouj] Ploujnikov]

I'll start by presenting some info about my system. You'll find the
actual problems (numbered) in the middle of this message.

I have my root file system on RAID 1
I use an initrd image to get my system going. The image was simply taken from:
http://sourceforge.net/project/showfiles.php?group_id=25076

I have added:

mount / -n -o remount,rw
[[ -z ${CDBOOT} ]] && start_addon evms

to /etc/init.d/checkroot
and removed anything evms related from /etc/init.d/checkfs

There are a few problems when I boot though:

1. the above "mount" command prints this:

mount: /dev/evms/system already mounted or / busy
mount: according to mtab, rootfs is already mounted on /

so the root fs isn't mounted read-only, and thus EVMS isn't protected
from other running instances:

Engine: Unable to open the ENgine lock file /var/locks/evms-engine:
Read-only file system. The Engine is not protected against other
instances of the Engine being opened at the same time.

2. It gets worse because I see:
"Activating EVMS" at least once after the checkroot script finishes running.

I cannot find where this might be coming from.
I went as far as commenting out:

start_addon dm-crypt

from /etc/init.d/localmount, but I still didn't find what is
activating EVMS unnecessarily.



Any help is appreciated.
