does it work if you boot with sysvinit ?

Hi, no, it's not working. I think the problem is in the kernel. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Can you boot the machine at all? Maybe the 'rescue' option from an install DVD then mount the root filesystem and 'chroot' into it. If you can get that far, try mkinitrd -m dm-snapshot and see if it will boot properly then. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I could solve the issues by editing /etc/sysconfig/kernel and adding a file to /etc/modules-load.d and therefore adding the missing modules but this change surprised me. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I tried this: Installed a (virtual) machine using opensuse 12.2 DVD, lvm based partitioning. Inside the vm i tried to create a snapshot - it failed with the message: snapshot: Required device-mapper target(s) not detected in your kernel Did a zypper ref && zypper up && reboot -> no change. But after modprobe dm-snapshot i can create the snapshot. So i created a snapshot of the root volume and rebuilt the initrd -> dm_snapshot got installed inside the initrd and then i rebooted. Result: VM cannot boot and spits "Can't process VL root_snap: snapshot target is missing from kernel?" So i assume, lvm2 commands should load devicemapper modules but fail to do that. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Thanks for finding that. The problem is that "lvm2.spec" contains %build MODPROBE_CMD=/sbin/modprobe \ %configure --prefix=/ \ .... Where as in 12.1 it was: %build CFLAGS="$RPM_OPT_FLAGS" MODPROBE_CMD=/sbin/modprobe \ ./configure --prefix=/ \ The 12.2 version apparently doesn't work and configure is run without MODPROBE_CMD being set properly, with exactly the results you see. I'll fix it by making it %build export MODPROBE_CMD=/sbin/modprobe %configure --prefix=/ \ The "save_var dm_modules" fix is an effective work around, but doesn't fix the real problem. Nevertheless the handling of dm_modules is somewhat untidy - I'll fix that. The 'dm-snapshot-origin' message is not overly significant. I'll make it go away, but it isn't a sign of any real problem (the dm-snapshot module provides both dm-snapshot and dm-snapshot-origin which are used as different parts of the snapshot implementation).

X=y \ ./configure .... is equivalent to X=y ./configure .... which tells bash to export X=y just for the command './configure'. This behaviour is explained in "SIMPLE COMMAND EXPANSION" in the 'bash' man page. X=y \ %configure .... becomes X=y CFLAGS=..... ; export CFLAGS ; ./configure .... so now "X=y" is not part of the same commands as "./configure", so the automatic export doesn't happen. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
