Creating the Physical Volumes To use disks in a volume group, you label them as LVM physical volumes
Warning :This command destroys any data on /dev/sda /dev/sdb /dev/sdc /dev/sdd

# pvcreate /dev/sda /dev/sdb /dev/sdc /dev/sdd

[root@net2isrv4 ~]# pvcreate /dev/sda /dev/sdb /dev/sdc /dev/sdd
Cannot use /dev/sda: device is partitioned

Physical volume “/dev/sdc” successfully created.
Physical volume “/dev/sdd” successfully created.

/dev/sda: device is partitioned … ini ada partisi GPT jadi harus dihapus terlebih dahulu dengan cara
# fdisk /dev/sda
Command (m for help): d
