3. metadb 생성

# metadb -a -f -c 3 c1t0d0s6 c1t1d0s6

옵션
-a	Attach a new database device (meta database 정보를 add)
-f	The -f option is used the create the initial static database force (강제로 추가)
-c	number : Specifiles the number of replicas to be placed on each device (meta database replica(복사본)의 개수 지정)
-d	생성되어 있는 metadb 삭제

※ metadb : Disksuite의 전체의 config 정보와 metadevice의 상태 정보를 가지고 있는 DB slice당 20M 정도면 충분하고, 최소 2개의 DB 복사본(Replicas)이 요구됨

3-1 metadb 생성 확인

# metadb

flags first blk 블록 개수

a u /dev/dsk/c1t0d0s6

a u /dev/dsk/c1t0d0s6

a u /dev/dsk/c1t0d0s6

a u /dev/dsk/c1t1d0s6

a u /dev/dsk/c1t1d0s6

a u /dev/dsk/c1t1d0s6

-> c1t0d0s6 슬라이스와 c1t1d0s6 슬라이스가 각각 3개씩 생성

 

4. MetaDB 정보 생성(d11에 c1t0d0s0 할당(원본 1개를 사본 1개만 만듬)

bash-2.05# metainit -f d11 1 1 c1t0d0s0

d11: Concat/스트립이 설정됨

 

4-1 d12에 c1t1d0s0 할당

bash-2.05# metainit d12 1 1 c1t1d0s0

d12: Concat/스트립이 설정됨

 

4-2 구성 확인

bash-2.05# metastat -p

d12 1 1 c1t1d0s0

d11 1 1 c1t0d0s0

 

4-3 d21에 c1t0d0s1 , d22에 c1t1d0s1 할당

bash-2.05# metainit -f d21 1 1 c1t0d0s1

d21: Concat/스트립이 설정됨

bash-2.05#

bash-2.05# metainit d22 1 1 c1t1d0s1

d22: Concat/스트립이 설정됨

d12 1 1 c1t1d0s0

d11 1 1 c1t0d0s0

 

5 이중화 설정

bash-2.05# metainit d10 -m d11

d10: 이중화가 설정됨

bash-2.05# metainit d20 -m d21

d20: 이중화가 설정됨

 

5-1 이중화 설정 확인

bash-2.05# metastat -p
