    🔽 구성 요소 설치 및 구성

       📦 초기 구성 - 컴퓨트 노드 (블록 스토리지 노드)

이번에는 블록 스토리지 노드 역할을 할 컴퓨트 노드에서 작업해 보도록할게요.

블록 스토리지를 따로 구성하여 블록 스토리지 노드를 구성해도 되고, 아니면 컨트롤러 노드에 구성해도 되지만, 주니는 어차피 인스턴스가 기동되고, 관리되는 컴퓨트 노드에서 모든 것이 처리되는 것이 좋겠다고 판단하여 위와 같이 구성하려고 해요.

어차피 오픈스택 서비스를 설치하면서 느낀 것은 모든 것이 모듈 단위로 설치하고, 구성해줘야 하는 부분이라 문제가 있음 따로 빼거나 할 수 있기 때문에 일단, 이렇게 구성해 보려고 해요.

apt install cinder-volume python3-mysqldb

pvdisplay

주니는 최초 컴퓨트 노드 OS 구성 및 HDD 구성 시에 위와 같이 /dev/sdb1과 /dev/sdc1을 각각 블록 스토리지로 사용하기 위해 PV, VG, LV를 잡아 주었어요.

vim /etc/lvm/lvm.conf devices{} 변경 전

 

vim /etc/lvm/lvm.conf devices{} 변경 뒤

728x90

인스턴스에서만 블록 스토리지 볼륨에 접근하게 하는 것이 좋은데, OS에서 볼륨 연결 장치에 대해 관리하고 있어요.
기본적으로 LVM 볼륨 검색 도구는 볼륨이 포함된 블록 스토리지 장치에 대해 /dev 디렉터리를 검색하게 된답니다.

프로젝트에서 LVM 볼륨을 사용할 경우 검색 도구는 해당 볼륨을 감지하고, 캐싱 하려고 시도하는데, 이 때, OS 및 프로젝트 볼륨에 대한 다양한 문제가 발생할 수 있어요. 그렇기 때문에 LVM을 블록 스토리지에게 할당할 VG을 포함하는 장치만 검색될 수 있도록 구성해 주어야 해요.

위와 같이 devices 부분에서 특정 장치를 허용하고, 다른 장치들은 거부하는 필터를 걸어줄 수 있는데, 필터 배열 내 각 항목에 accept에 대한 내용으로 a를 붙혀주게 되고, reject에 대해 r을 붙혀주고, 그 다음 장치 이름에 대한 정규 표현식으로 표기해 주면 되요.

배열은 그 외 다른 장치에 대한 접근을 거부하기 위해 r/.*/로 설정해 주어야 해요.
이 때, vgs-vvvv 명령어를 사용하여 필터 테스트를 진행할 수 있어요.

스토리지 노드에서 LVM을 운영체제 디스크로 사용할 경우 연결된 장치 또한 필터에 추가해줘야 해요. 주니의 운영체제 디스크는 LVM으로 구성되어 있고, /dev/sdd로 구성이 되어 있어요.

그리고, 컴퓨트 노드에서 LVM을 운영체제 디스크로 사용할 경우 해당 노드의 /etc/lvm/lvm.conf 파일 내 필터를 구성하여 운영체제 디스크만을 허용하도록 해줘야 해요. (스토리지 노드 따로 구성 시)

vim /etc/cinder/cinder.conf [DEFAULT] 변경 전

 

 

vim /etc/cinder/cinder.conf [DEFAULT] 변경 뒤

3번째 줄에 IP는 블록 스토리지 노드의 IP를 적어주면 되고, (현재 구성은 컴퓨트 노드)
9번째 줄 password는 RabbitMQ 구성 시 생성한 비밀번호를 입력해 주면 됩니다.

vim /etc/cinder/cinder.conf [database] 변경 전

 

vim /etc/cinder/cinder.conf [database] 변경 뒤

위의 password 부분은 DB 계정의 암호를 입력해 주면 돼요.

vim /etc/cinder/cinder.conf [keystone_authtokne], [oslo_concurrency] 생성

28번째 줄 servicepassword는 컨트롤러 노드에서 Keystone에 cinder 계정 생성 시 입력했던 암호를 입력해 주면 돼요.


여기까지 되었다면 저장하고 나옵니다.

chmod 640 /etc/cinder/cinder.conf; chgrp cinder /etc/cinder/cinder.conf

그런 뒤 설정 파일의 권한과 소유 그룹을 변경해 줍니다.

systemctl restart cinder-volume; systemctl enable cinder-volume

이제 cinder-volume 데몬을 재기동하고, 서비스에 등록해 주면 돼요.

 

 

 

       📦 LVM 구성 - 컴퓨트 노드 (블록 스토리지 노드)

이제 스토리지로 사용할 HDD에 대한 설정을 해줘야 하는 부분이에요.

참고로 주니는 미리 LV까지 만들었는데, 메뉴얼에는 VG까지만 만들고, 해당 VG에 Extent(익스텐트) 크기를 32MB로 지정해 주는 걸로 나와서 VG, LV를 삭제하고, VG를 다시 구성해 볼게요.

최초 LV부터 삭제합니다.

lvdisplay

위 LV를 삭제할거에요.

lvremove /dev/{VG 이름}/{LV 이름}

만약 위와 같이 사용중이라고 나온다면 마운트 해제를 하지 않아서 발생한 문제에요.

umount {경로}

위와 같이 LV가 마운트된 디렉터리를 마운트 해제 해 줄 수 있어요.

 

lvremove /dev/{VG 이름}/{LV 이름}

이렇게 하면 LV를 삭제할 수 있어요.



이번에는 VG를 삭제하고 다시 구성해 볼게요.

vgs

위의 BlockStorageVG를 삭제하고 다시 만들거에요.

참고로 해당 VG에는 두 개의 PV가 물려 있기 때문에 이 작업을 다시 해줘야 해요.

즉, 하나의 VG에 두 개의 PV를 물리게 해서 구성해 주어야 하는데, 이 부분은 이 곳을 참고해 주시면 좋을 거 같아요.

vgremove {VG 이름}

위와 같이 VG를 삭제해 주었어요.

pvs

sdb1과 sdc1 PV를 VG에 추가하여 구성해 볼게요.

vgcreate -s 32M {VG 이름} {PV 장치명}

위와 같이 VG를 만드는데, 32MB 익스텐트 크기를 지정해 주었어요.

32MB 익스텐트를 사용하면 논리 볼륨을 적절한 크기로 분할하고, 관리할 수 있고,
작은 파일부터 큰 파일까지 다양한 크기의 데이터를 효과적으로 다룰 수 있어요.

LVM을 사용하는 시스템에서는 익스텐트 크기를 조정할 수 있지만, 한번 설정한 크기는 일반적으로 변경하기 어려워요.

 

💡 LVM의 Extent
Extent는 LVM(논리 볼륨 매니저)에서 사용되는 단위로 논리 볼륨 관리의 중요한 역할.

1. 크기: 익스텐트는 고정 크기의 블록 단위. 예를 들어 32MB 크기의 익스텐트는 32MB 크기로 고정.
2. 할당: 논리 볼륨을 만들거나, 확장할 때, 익스텐트 단위로 공간을 할당하거나 해제. 해당 내용은 데이터의 조각을 다루는 방식으로 더 큰 논리 볼륨을 만들고, 필요한 만큼의 익스텐트를 할당하거나, 해제하여 공간을 효율적으로 관리하기 위하여 사용.
3. 일관성: 익스텐트 크기는 모든 논리 볼륨에서 동일하며, 이는 데이터 일관성 보장.

반응형

vgextend BlockStorageVG {PV 장치 명}

그리고 위와 같이 다른 PV를 추가해 주었어요.

vgs

 

 

 

       📦 패키지 설치 및 초기 구성 - 컴퓨트 노드 (블록 스토리지 노드)

apt install -y targetcli-fb python3-rtslib-fb

최초 위와 같이 패키지를 설치해 주었어요.

vim /etc/cinder/cinder.conf enabled_backends 부분 변경 전

 

vim /etc/cinder/cinder.conf enabled_backends 부분 변경 뒤

vim /etc/cinder/cinder.conf [lvm] 생성

여기서 LVM 설정 관련한 내용을 추가해 주는데, 40번째 줄에는 위에서 만든 VG의 이름을 넣어주어야 해요.


여기까지 했다면 저장하고, 나옵니다.

systemctl restart cinder-volume

그런 뒤 데몬을 재기동해 주었어요.

       📦 초기 구성 - 컴퓨트 노드

만약 블록 스토리지 노드와 컴퓨트 노드가 분리되어 있다면 이 부분은 컴퓨트 노드에서 진행해야 해요.

주니는 블록 스토리지 노드가 컴퓨트 노드이기 때문에 동일한 곳에서 진행합니다.

vim /etc/nova/nova.conf [cinder] 생성

위 내용을 맨 밑에 추가해 주었어요.

여기까지 되었다면 저장하고, 나옵니다.

systemctl restart nova-compute

그런 뒤 노바 컴퓨트 데몬을 재 기동 해 주었어요.

 

       📦 볼륨 생성 - 컨트롤러 노드

이제 각 인스턴스에 볼륨을 추가할 계정으로 로그인하고, 10GB의 가상 볼륨을 생성해 보려고 해요.
어느 노드에서 작업해도 되지만, 주니는 컨트롤러 노드에서 작업해 보았어요.

echo "export OS_VOLUME_API_VERSION=3" >> ~/keystonerc; source ~/keystonerc

작업 전 환경 변수 설정을 해 주었어요.

openstack volume create --size 10 disk01

위 명령어로 10GB짜리 가상 볼륨을 만들어 줄 수 있어요.

openstack volume list

볼륨 목록도 잘 나오는 걸 확인할 수 있어요.

 

 

 

       📦 잘 구성 되었나? 🤔

openstack volume service list

위와 같이 볼륨 서비스 목록에 정상적으로 출력이 되고, State가 up이면 잘 구성한 것이에요.
