I'm using Linux 2.4.10 and lvm 1.0.1-rc4. Without devfs, perform the following: 1. Create a physical volume on some LVM partition (e.g., /dev/hda7). 2. Run pvscan--it shows the physical volume /dev/hda7. 3. Create a volume group (vg7) using the physical volume created in step 1. There now exists a device /dev/vg7/group. 4. Run vgscan--it shows the active volume group vg7. 5. Run vgchange -an. The device /dev/vg7/group still exists. 6. Run vgscan--it shows the inactive volume group vg7. Rebuild the kernel with devfs and perform the following: 1. Run pvscan--it shows the physical volume /dev/ide/host0/bus0/target0/lun0/part7. 2. Run vgscan--it shows the active volume group vg7. 3. Run vgchange -an. The device /dev/vg7/group is gone. 4. Run vgscan--it seg faults. In fact, any command that attempts to open /dev/ide/host0/bus0/target0/lun0/part7 seg faults. This does not appear to be a conversion problem from non-devfs to devfs; it happens even if you start with devfs.
