Linux Fdisk shows error for LVM created disk.

Gulam Mohiuddin — Thu, 07 Jun 2007 09:54:07 GMT

I used LVM to configure new IBM RAID drive into the system. I didn't use fdisk to initialize the disk.

But when I run fdisk -l - I get the following error:

Error: Disk /dev/sdc doesn't contain a valid partition table

Followings are the all the steps I used for Configuring LVM disk on RHEL 4.0

partprobe
pvcreate /dev/sdc
vgcreate VolGroup01 /dev/sdc
lvcreate -L 30G -n LogVol02 VolGroup01
mkfs -t ext3 /dev/VolGroup01/LogVol02

Also What is "/dev/mapper/VolGroup01-LogVol02" shown in the output of df command?

Thanks,

Gulam.

HI Gulam

That error is usual when there is no filesystem in the new disk
if the fileystem was created usin fdisk u will not get this error .
And for output as /dev/mapper/... its thelinux lvm mapper driver loaded in linux .

Considering this information (not error):

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

And this information:

PV /dev/sdc VG VolGroup01 lvm2 [279.39 GB / 249.39 GB free]

That means that the while disk (sdc) was used as an LVM physical volume, without creating a partition 8e on it, it's perfectly valid.

And /dev/mapper/VolGroup01-LogVol02 is mounted on /u03, the line was cut because was too long, that's all. Use df -P if you don't want to cut lines.
