2.6 unknown partition table

2.6 unknown partition table

[Shane Shrybman]

Hi,

I noticed this in the logs yesterday on 2.6.0-test11-mm1 and upgraded to
2.6.0-mm1, but its still there. I use LVM on that disk and it is working
fine, (LV file systems are mountable and useable).

I recently was experimenting with raid5 on five, 100MB LVs on that disk.
Could that maybe have caused this? Since everything has been working
fine I don't know at which kernel version this appeared although I have
been using 2.6 for over a year.

Advice?

# fdisk -l /dev/hdg

Disk /dev/hdg: 16 heads, 63 sectors, 155114 cylinders
Units = cylinders of 1008 * 512 bytes

Disk /dev/hdg doesn't contain a valid partition table

Everything is fine. You put your physical volume directly on the
harddisk, not in a partition, so you don't have a partition table.
vgscan recognizes the hard disk itself as LVM physical volume anyway
that's why it works.

If you want to get rid of this, the next time you create a PV please
create a partition first with fdisk, e.g. /dev/hdg1 with type 8e (LVM)
and then pvcreate /dev/hdg1.
