I'm not sure if this is a bug but I suspect there needs to be some clarification in regards to how LVM behaves with devfs. I will describe my situation first. I am booting to a 2.4.19-16 kernel (mandrake 9.0) with devfs enabled. I am using LVM version 1.0.3. I boot to this kernel WITHOUT mounting or enabling devfs. I attempt to create physical volume with the following command: pvcreate -ff -y /dev/hdb It returns the error: pvcreate -- device "/dev/hdb" has a partition table Here is my /proc/partitions: 22 0 15972 hdc 3 0 20066251 ide/host0/bus0/target0/lun0/disc 3 1 313267 ide/host0/bus0/target0/lun0/part1 3 2 265072 ide/host0/bus0/target0/lun0/part2 3 3 1 ide/host0/bus0/target0/lun0/part3 3 5 3076416 ide/host0/bus0/target0/lun0/part5 3 64 20066251 ide/host0/bus0/target1/lun0/disc I then try to write zero's MBR: dd if=/dev/zero of=/dev/hdb bs=512 count=1 blockdev --rereadpt /dev/hdb It returns the same error: pvcreate -- device "/dev/hdb" has a partition table The bug, I believe, is that pvcreate is incorrectly stating that there is a partition table on /dev/hdb. What I believe the error should return is some sort of "file/device not found", because pvcreate will create the physical volume if I create the /dev/ide/host0/bus0/target1/lun0/disc file according to devfs naming. The only way I am able to create a physical volume is into a partition, not an entire disk. There are other problems I am running into relating to LVM and devfs but I am not currently able to clearly state what they are. Perhaps, a fix of what I mentioned above will solve those issues also. Any help is greatly appreciated.
