lvm initialization hangs during boot or when running /etc/init.d/lvm start

[Pierfrancesco Caci]

Binary package hint: lvm-common

Updated system yesterday (2007.04.02), relevant updated packages were lvm-common, mdadm and udev.
While the update finally seems to have fixed a long standing race condition in mdadm preventing boot,
it seems to have broken lvm. The system will freeze at lvm start (right after turning up the parport).
If I interrupt the process (alt-sysrq-e) I can do a mount -a and it will find all the volumes correctly. From that point on,
I can resume the boot process by forcing a telinit 1; telinit 2

Also, running /etc/init.d/lvm start seems to hang at the same point.

Please provide the output of the following:

  dpkg-query -W devmapper dmsetup libdevmapper1.02 udev volumeid libvolume-id0 lvm2 lvm-common mdadm

Also could you try booting your system with init=/bin/bash and then remove the symlink for this init script, followed by exec /sbin/init

See if your system boots fine then.

If it does, boot into single-user mode and then run the script with:

  sh -x /etc/init.d/lvm2 >/dev/lvm.log 2>&1

and attach the output to this bug

Can you confirm whether or not you have evms installed?

[Pierfrancesco Caci (pf-caci)]

the following evms packages are installed

ii evms 2.5.5-18ubuntu2 Enterprise Volume Management System (core)
ii evms-cli 2.5.5-18ubuntu2 Enterprise Volume Management System (CLI)
ii evms-ncurses 2.5.5-18ubuntu2 Enterprise Volume Management System (ncurses
ii libevms-2.5 2.5.5-18ubuntu2 Enterprise Volume Management System (library

I've never used it actually, so if this is the culprit, I can as well get rid of it.

[Pierfrancesco Caci (pf-caci)]

so, booting with init=/bin/bash, making chmod -x /etc/init.d/lvm and finally exec /sbin/init
I can boot and this is the output of the lvm script as you requested:

 $ cat /root/lvm.log
+ modprobe lvm
+ modprobe lvm-mod
+ modprobe dm-mod
+ set -e
+ . /lib/lsb/init-functions
+ FANCYTTY=
+ [ -e /etc/lsb-base-logging.sh ]
+ . /etc/lsb-base-logging.sh
+ . /etc/default/rcS
+ TMPTIME=0
+ SULOGIN=no
+ DELAYLOGIN=no
+ UTC=yes
+ VERBOSE=no
+ EDITMOTD=yes
+ FSCKFIX=no
+ test -x /sbin/lvmiopversion -a -x /sbin/vgscan -a -x /sbin/vgchange
+ test -f /etc/default/lvm-common
+ . /etc/default/lvm-common
/etc/init.d/lvm: 57: Syntax error: Bad substitution

as a side note, the evms scripts returns "failed" during the boot process.

[Pierfrancesco Caci (pf-caci)]

purging all evms packages seems to have cured the problem.
nice

This should be fixed in today's devmapper, udev and evms uploads
