1.以SR方式增加硬盘:
查看新增加的硬盘分区:

fdisk -l
Disk /dev/sda: 42.9 GB, 42949672960 bytes
255 heads, 63 sectors/track, 5221 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 523 4194304 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 523 1045 4194304 83 Linux
/dev/sda3 1045 5221 33549043 8e Linux LVM
Disk /dev/sdb: 1073 MB, 1073741824 bytes
255 heads, 63 sectors/track, 130 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdb doesn't contain a valid partition table
新建为SR:
xe sr-create type=lvm content-type=user device-config:device=/dev/sdb name-label=sr2

2.新加硬盘以LVM方式扩容到VG:
新建PV:
pvcreate /dev/sdb
查看VG名称:
vgscan
扩充PV到VG:
vgextend VG_XenStorage-5a953701-83ab-b22b-3903-c3932d3a710d /dev/sdb
