ZFS create pool

by

지난 ZFS 설치관련 포스트에 이어 ZFS pool을 생성하는 글을 작성한다.

Check Disk

먼저 pool로 묶을 디스크를 확인한다.

fdisk -l

본 글에서는 sda, sdb, sdc 3가지를 가지고 pool을 생성할 것이다.
현재 sda, sdb, sdc는 iscsi initiator을 이용해 디스크화한 형태이다.

ZFS Create pool

raid와 비슷한 구조로 raid5를 사용하고 싶지만 해당 명령어가 존재하지 않아 raidz를 사용하였다.

sudo zpool create zfspool raidz /dev/sda /dev/sdb /dev/sdc

pool의 상태확인을 통해 생성유무를 확인한다.

 zpool status
zpool status
  pool: zfspool
 state: ONLINE
config:

        NAME        STATE     READ WRITE CKSUM
        zfspool     ONLINE       0     0     0
          raidz1-0  ONLINE       0     0     0
            sda     ONLINE       0     0     0
            sdb     ONLINE       0     0     0
            sdc     ONLINE       0     0     0
