So, I'm working on setting up a system that's going to run a series of Xen virtual machines. Each of these virtual machines are going to be basically identical, with only slight differences in a specific application for testing. Rather than duplicate the initial setup in whole, I created it as a logical volume, and created a second as a snapshot of the first, with a couple of gigs of wiggle room. These partitions, at the time of creation, were addressable as /dev/xen/vm1 and /dev/xen/vm2 (alternately, /dev/mapper/xen-vm1 and /dev/mapper/xen-vm2). However, after doing a reboot of the host machine, the partitions are no longer addressable via the /dev/<vol group name>/<logical volume name> syntax. They're only available as /dev/dm-1 and /dev/dm-2 `ls -altr /dev/xen/` shows that the device files for vm1 and vm2 do not exist. The device files for my other logical volumes, which are not snapshots, do exist. Doing `lvscan` shows this: ACTIVE '/dev/xen/vm0' [20.00 GB] inherit inactive Original '/dev/xen/vm1' [20.00 GB] inherit inactive Snapshot '/dev/xen/vm2' [2.90 GB] inherit ACTIVE '/dev/xen/vm3' [20.00 GB] inherit So, I'm assuming that the "inactive" state is somehow related to the device files being missing; and that the inactive state is somehow related to the snapshot-nature of the partitions. Can anyone point me to what I need to do to get those device files back? (Though I agree that it could be done, I don't really consider manual creation of the files to be a good option; I'm going to be creating and destroying virtual machines on this box quite often, and need the management tools to be working.) On a side note: I _can_ mount these partitions, read data from them, etc, as /dev/dm-1 and the like. The problem with that is that the device files don't necessarily refer to the same partition all the time. If you have dm-1..dm-6, and delete dm-2, then dm-3..dm-6 slide up one and become dm-2..dm-5. Not handy when those device files are entered into config files for virtual machines. -- Check the headers for your unsubscription address For additional commands send e-mail to suse-linux-e-help@suse.com Also check the archives at http://lists.suse.com Please read the FAQs: suse-linux-e-faq@suse.com
