Re: [gentoo-user] root on EVMS, evms_activate, checkroot, rw/ro mount, gah
Actually, "evms" is all I have in RC_VOLUME_ORDER in /etc/conf.d/rc I'll try to remove the EVMS activation from checkroot now and see how that works. Wow, it looks like doing this fixed all the problems. No re-mounting tricks. EVMS gets activated once, and on a writeable filesystem. Thanks a lot Richard. Now I'll see about cleaning up the wiki HOWTO. -- () ASCII Ribbon Campaign /\ - against HTML mail & vCards -- gentoo-user@gentoo.org mailing list

Hmm, why was this necessary?
I just got that from:
http://gentoo-wiki.com/HOWTO_setup_evms
(I'll try to fix the HOWTO once I figure out how to setup my system)
In baselayout 1.12.5-r2,
(thankfully that's the baselayout version I have)
the checkroot
script will already remount the root filesystem as rw if necessary,
and the /sbin/rc script will do a "start_addon evms" after starting
checkroot and modules, if evms appears in RC_VOLUME_ORDER in
/etc/conf.d/rc.

My checkfs doesn't have anything related to evms to begin with...
Yeah, neither does mine. I was just referring to what the wiki HOWTO said.

Could it have already been activated by the initrd?
I'm not sure what you mean by activated. I think this message results
from this code:
mount / -n -o remount,rw
which tries to remount root read-write. If you mean that root was
already mounted by the initrd, you are right.

Probably because you have evms in RC_VOLUME_ORDER in /etc/conf.d/rc,
which causes /sbin/rc to do a "start_addon evms" right after
checkroot.
Actually, "evms" is all I have in RC_VOLUME_ORDER in /etc/conf.d/rc
I'll try to remove the EVMS activation from checkroot now and see how
that works.
Thanks.

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