Problem in creating LVM in RHEL 5 Server

Hi All

I'm facing a problem while creating LVM in Redhat Linux Enterprise 5 Server
Problem is when i create physical volume via pvcreate command it creates physical volume successfully but after when i try to create Volume group with the command of vgcreate then i get below error message
[root@cjpunjabiradio ~]# vgcreate /dev/hda{10,11}
/dev/hda10: already exists in filesystem
New volume group name "hda10" is invalid

Why the above mention error is coming. I have checked this mention partition is not using in another volume group. Please help.

Thanks

Are you sure? Might not be in another volume group but perhaps being used elsewhere? What does fdisk -l provide or a simple mount command.

Hi
I have checked via fdisk -l and also from mount command this drive is not using by another volume group. Please assist....

Can you paste the output of fdisk -l?

how about you give it a volume group name?

Code:

vgcreate vg01 /dev/hda{10,11}

Yes u are right twk i was commiting a mistake i forgeted to put volume group name because without giving it was assuming hda10 as volume group name and hda 10 is partition so it was not able to create volume group name hda10. Finaly i'am able to create volume group. Thanks to all people for your support. Bye.
