XenServer 로컬 스토리지 추가

XenServer를 설치할 때 특정 디스크를 선택하여 O/S를 선택한다. 

추가 디스크 적용은 터미널에서 아래와 같이 추가하여 사용한다.

LVM을 생성하기 위하여  UUID를 확인한다.

# xe host-list

uuid ( RO)                : 9e5e2a02-2305-41cf-b74e-2850ebc85d61

          name-label ( RW): xenserver

    name-description ( RW): Default install of XenServer

위에서 확인한 UUID,name-label, device(마운트되어있는 디스크 디바이스)를 선택하여 생성한다.

# xe sr-create host-uuid=9e5e2a02-2305-41cf-b74e-2850ebc85d61 content-type=user name-label="Local storage2" shared=false device-config:device=/dev/sdb type=lvm

정상적으로 표시가되는지 확인

최종적으로 아래와 같이 XenCenter에서 확인할 수 있다.

O/S설치 및 Template설치 시 해당 디스크를 선택하여 용량을 할당하면 된다.

[ Guest Host에서 진행 ]

새로운 디스크를 포맷하고 적용시킴

먼저 XenCenter에서 신규 스토리지를 할당하고 진행한다.

아래 디바이스(/dev/xvdb)명은 VM이 모두 동일하다.

# fdisk /dev/xvdb

Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel

Building a new DOS disklabel with disk identifier 0xd1978864.

Changes will remain in memory only, until you decide to write them.

After that, of course, the previous content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

WARNING: DOS-compatible mode is deprecated. It's strongly recommended to

         switch off the mode (command 'c') and change display units to

         sectors (command 'u').

Command (m for help): m

Command action

   a   toggle a bootable flag

   b   edit bsd disklabel

   c   toggle the dos compatibility flag

   d   delete a partition

   l   list known partition types

   m   print this menu

   n   add a new partition

   o   create a new empty DOS partition table

   p   print the partition table

   q   quit without saving changes

   s   create a new empty Sun disklabel

   t   change a partition's system id

   u   change display/entry units

   v   verify the partition table
