After adding a new virtual HDD, I run a scan:
Code: Select all
echo "- - -" > /sys/class/scsi_host/host0/scan
echo "- - -" > /sys/class/scsi_host/host1/scan
echo "- - -" > /sys/class/scsi_host/host2/scan
Code: Select all
fdisk -l
The newly added hard-disk was then insert into the HSM's LVM volume with the following commands:
Code: Select all
pvcreate /dev/sdh
vgextend volgrp2 /dev/sdh
lvextend -L +250G /dev/volgrp2/hsmvol
After creating a partition, it will become /dev/sdh1:
Code: Select all
pvcreate /dev/sdh1
vgextend volgrp2 /dev/sdh1
lvextend -L +250G /dev/volgrp2/hsmvol
What is the difference and impact between having LVM using HDD with partition and without? Does this apply to both Ubuntu and CentOS?
