Ah, ok, I'm seeing. Well, I think that's a problem with LVM2. At the moment the device files are created either when a volume group gets activated or when it is already active and you add a logical volume. But when the volume group got activated by the ramdisk and the system switches the root filesystem, you now don't have the devices files. I think that's where "lvm mknodes" should kick it, but... not implemented yet. And you can't deactivate and reactivate the volume group because the root filesystem on it is mounted. Great. :D So it looks like you must create the device files manually. cd /dev/mapper mknod volumegroupname-logicalvolumename b 254 0 mknod volumegroupname-logicalvolumename b 254 1 ... After that you also should create the symlinks cd /dev/volumegroupname ln -s ../mapper/volumegroupname-logicalvolumename logicalvolumename ... Since you already put an ls command into the ramdisk before you should know which minor got assigned to which volume. Or, perhaps this should work: AFAIK if you have a directory /initrd on your root filesystem, the old ramdisk should be moved there after the root filesystem is mounted, so you can just copy the directories and device files that got create there in /dev (/initrd/dev/mapper and /initrd/dev/volumegroupname) to your /dev. But I have never tested this. This sounds rather ugly and complicated, but it only occurs when switching from LVM1 to LVM2 while having it mounted (because you can't activate it via LVM2 while running on the real filesystem where the device nodes should be created correctly. Or wait until the mknodes command is finished or implement it yourself. ;-) -- Christophe Saout <christophe@saout.de> _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
