And try "vgreduce my_volume_group /dev/cciss/c0d1p1" to remove your physical volume group.<BR /><BR />Regards,<BR />Sung Tue, 13 Jun 2006 15:02:51 GMT Sung Oh 2006-06-13T15:02:51Z https://community.hpe.com/t5/operating-system-linux/how-do-i-remove-a-physical-volume-in-redhat-linux-as-4/m-p/3805113#M23836 I have created a physical volume using the following command on my Linux server:-<BR /><BR />pvcreate /dev/cciss/c0d1p1<BR /><BR />How do remove the physical volume ?<BR /><BR />I have tried using pvremove (see below) and receive an error. Can anyone help me?<BR /><BR />[root@metis cciss]# pvremove -v /dev/cciss/c0d0p1<BR /> No physical volume label read from /dev/cciss/c0d0p1<BR /> Can't open /dev/cciss/c0d0p1 exclusively.

Run fdisk /dev/cciss and then delete the partition by running option d and choosing the number of the partition.

That should free it up to run pvremove. You can also run it under the GUI system-config-lvm to see a good graph of how it's set up.
