도와주세요! 업그레이드 후 완전히 실패했습니다

안녕하세요,

최근 업그레이드(6에서 7로)를 실행했을 때, 중복된 사용자 이름이라는 이유로 rake db:migrate가 실패했습니다. 저는 리눅스 커맨드라인에 익숙하지 않아서 문제를 해결하기 위해 Rails 콘솔을 입력해 보았지만, 데이터베이스에 연결할 수 없어 콘솔이 로드되지 않았습니다. 그 후 구글링을 통해 /etc/init.d/postgresql restart를 시도해 보았으나 다음 오류와 함께 실패했습니다:

[....] Restarting PostgreSQL 12 database server: main[....] 
Error: /usr/lib/postgresql/12/bin/pg_ctl /usr/lib/postgresql/12/bin/pg_ctl start -D /shared/postgres_data -l /var/log/postgresql/postgresql-12-main.log -s -o -c config_file="/etc/postgresql/12/main/postgresql.conf" exited with status 1: 2021-03-08 20:19:10.354 UTC [763] 
FATAL: database files are incompatible with server 2021-03-08 20:19:10.354 UTC [763] 
DETAIL: The data directory was initialized by PostgreSQL version 13, which is not compatible with this version 12.3 (Debian 12.3-1.pgdg100+1). p[FAIL: could not start server Examine the log output. ... failed!
 failed!

그 다음 /etc/init.d/postgresql restart version 12.3을 시도해 보았지만, 오류 메시지는 없었지만 다른 메시지도 나오지 않았습니다. 그리고 여전히 psql에 로그인할 수 없습니다(최소한 이 포럼에서 찾은 sudo -u postgres psql discourse 명령을 사용하는 경우).

누군가 서버를 복구하는 방법에 대해 조언해 주실 수 있을까요? 그리고 왜 최신 업그레이드가这么大的 오류를 일으킨 것일까요? 저는 30분 설치 방법을 사용했고, 모든 것이 최대한 표준 설정 그대로입니다. 이 문제를 해결해 주시는 분께 비용을 지불할 의향도 있습니다.

@pfaffman 님은 이 같은 지원에 전문적이니, 그분에게 연락해 보시는 것이 좋겠습니다.

정확한 실패 로그를 가지고 계신가요? 조금 스크롤을 내려보실 필요가 있을 수 있지만, 저는 다음 사항에 대해 궁금합니다.

  1. 실패한 마이그레이션의 이름
  2. 실패를 유발한 문장

어딘가에 존재하던 버그로 인해 대소문자가 다른 사용자 이름이 허용되고 있었습니다. 이후 수정되어 더 이상 그런 일이 일어나지 않도록 했습니다.

기존 컨테이너를 다시 실행하고 UX를 통해 수정할 수 있을지도 모릅니다.

하지만 최근에 커맨드 라인 업그레이드를 하지 않았다면, 데이터베이스 업그레이드도 추가로 필요하므로 상황이 더 복잡해질 수 있습니다.

상황이 그보다 훨씬 나쁘지 않다면, 내일 오전(태평양 시간)에 직접 수정하겠습니다. Redirecting…

오늘 밤 안에 해결을 원하신다면 더 많은 비용을 지불할 수 있습니다. 그렇다면 서둘러 Jay@literatecomputing.com으로 이메일을 보내주세요. 최소한 서비스는 다시 복구할 수 있을지도 모릅니다.

Spinning up 3 Unicorn worker(s) that were stopped initially

그 후, 웹 인터페이스보다 더 견고할 것 같아서 SSH를 통해 업데이트를 실행했습니다. (2020년에는 몇 달 동안 웹 인터페이스가 어떤 것도 업데이트를 거부해서 항상 SSH를 통해 진행해야 했습니다.) 명령줄에 업데이트 명령을 입력하자 많은 양의 데이터를 다운로드한 끝에 rebuild app 명령을 실행하라고 알려주었습니다. 해당 명령을 실행하자 동일한 오류가 발생했습니다. 주변 줄이 동일했는지 확신할 수는 없지만 복사하지 않았으며, 데이터베이스 마이그레이션 중간에 분명히 이 index_username_on_users 문제가 있었습니다.

TL;DR: 출력을 올바르게 해석한다면, 문제는 RenameEnglishLocale 마이그레이션의 execute("UPDATE users SET locale = 'en' WHERE locale = 'en_US'") 명령에서 발생했습니다.

이전에도 이 오류를 본 적이 있습니다. users 테이블에 내부 손상(internal corruption)이 있을 때 발생하는 문제입니다.

어떤 방식으로든 테이블에 중복된 “user” 레코드가 존재합니다. 이전 버전에서, 업그레이드 과정에서, 또는 갑작스러운 종료(rude shutdown) 시점에 들어온 것으로 보입니다. 정확히 왜 발생하는지는 아직 알지 못하지만, 실제로 발생한 것을 여러 번 확인했습니다.

두 가지 대안이 있습니다:

  1. 운이 좋다면 ./launcher start app을 실행한 후 rails c를 실행하고, DB.query('select * from users where username='Martina_S')를 실행한 뒤 마지막 Martina_S를 Martina_S1과 같은 이름으로 변경할 수 있습니다.

  2. 운이 나쁘면 앱을 시작할 수 없을 것입니다. 이 경우 데이터 컨테이너를 부팅하여 psql에서 위의 작업을 실행해야 합니다.

빠른 답변 감사합니다! 데이터 컨테이너를 어떻게 부팅하나요? ./launcher start app을 실행한 뒤 rails c를 입력해 보았지만, 데이터베이스가 실행되지 않아 Rails가 시작되지 않습니다. /etc/init.d/postgresql restart를 시도해 보았지만, 첫 번째 게시글에서 확인하신 오류가 발생했습니다. PostgreSQL 버전이 호환되지 않는다는 내용이었죠 (Debian LTS는 12.x만 지원하는데, 최근 Discourse 업그레이드가 데이터를 13.0으로 마이그레이션한 것 같습니다??). 저는 Rails 개발자이므로 SQL로 이 문제를 해결하는 데는 문제가 없습니다. 하지만 리눅스 명령줄에서 PostgreSQL 업데이트 실패로 보이는 문제를 어떻게 수정해야 할지 전혀 감이 잡히지 않습니다.

7

예제 데이터 컨테이너는 sample 디렉터리에서 확인할 수 있습니다.

올바른 위치를 지정하기만 하면, 컨테이너에 진입하여 psql를 실행할 수 있습니다.

네, 이미 13으로 업그레이드되었습니다.

@pfaffman 님이 수정해 주셨어요. 이 분 추천합니다 :slight_smile:
