Re: [linux-lvm] lvm/devfs bug?

[rich turner <rich@storix.com>]

does anyone recognize this as a bug within lvm?

there clearly is not a partition on sda (according to /proc/partitions)
but pvcreate thinks there is one. if pvcreate examines only
/proc/partitions for disk partitions and there is not a partition on a
disk then why does pvcreate fail? i may not understand all of the
underlying behavior of pvcreate but it appears to be failing when it
shouldnt. is this a bug?
