That may be the problem. We're using the stock Debian kernel/initrd combination. At runtime devfs is not in use, but apparently it is temporarily used during the initrd process. The VG itself was created using a Knoppix (non-devfs, I believe) boot CD. Is this a problem that can be solved using vgcfgbackup/vgcfgrestore? While I'd have to boot off a CD of some sort to do it (since / is on the VG and hence it can't be deactivated) I don't mind doing that if it's a once-off. > My solution was to patch my kernel with device-mapper, and install EMVS > 2.2.0.

We're using a stock Debian kernel, which doesn't have EVMS. :-/ It sounds like I may have to wait until they make a 2.6 image available which will allow us to use devmapper instead.
