مشكلة في استعادة Discourse من نسخة احتياطية (3.4، قاعدة بيانات كبيرة جدًا)

Dmitry_Krasnoperov · 10 يناير 2025، 11:08ص

Hi there,
We are one of your early bird users, we are using Discourse since 2015.
It works just fine until latest update with Postgres update included (possibly 3.4?). We have one backup points before this update. We decide to make clean install then restore from this backup.

OS: Ubuntu 24.04.1 LTS (latest updates) + docker 26.1.3
Trying to restore large discourse backup (44GB, single site) to a blank container.

Automated restore fails on DB migration with following error:
PG::DuplicateColumn: ERROR: column “notification_level” of relation “user_chat_channel_memberships” already exists (PG::DuplicateColumn)

logs:
Specifically, the migration stops after deploying the SQL archive because a column in the database is not unique.
column "notification_level" of relation "user_chat_channel_memberships" already exists

كيفية إصلاح ملف SQL بحيث يعمل db:migrate بنجاح؟

pfaffman · 10 يناير 2025، 1:45م

ما هو الالتزام الذي عليه الموقع القديم؟

كانت هناك بعض الانتكاسات حيث تضمن التزام ترحيلاً لم يكن ينبغي أن يتضمنه. تخميني هو أن هذه إحدى تلك الحالات.

RGJ · 10 يناير 2025، 1:54م

هل لديك نفس مجموعة الإضافات بالضبط على كلا المثيلين؟
على أي تثبيت هو Discourse الخاص بك، وعلى أي تثبيت من إضافة الدردشة؟

Dmitry_Krasnoperov · 10 يناير 2025، 2:36م

أقدر مشاركتك الطيبة. تفريغ قاعدة بيانات SQL بحجم 45 جيجابايت يستغرق وقتًا طويلاً للعمل عليه.
حاولت تشغيل تحديث واجهة المستخدم الرسومية في 31 ديسمبر مما أدى إلى تعليق ترحيل قاعدة البيانات. الموقع القديم اختفى منذ 06 يناير، كل ما لدي هو تفريغ SQL وملفات الوسائط التي تم تحميلها. أحاول تشغيل موقع جديد واستعادة قاعدة بياناتي هناك. أقوم بتشغيل عدد قليل من الإضافات فقط في ملف YAML الخاص بي:

RGJ · 10 يناير 2025، 2:45م

ما هو اسم ملف النسخة الاحتياطية لديك؟ (يحتوي على معلومات حول آخر عملية ترحيل تم تشغيلها)

هذا مثير للاهتمام.

هذه التعارضات على جداول بسيطة إلى حد ما والمعرفات المتعارضة منخفضة
النسخة الاحتياطية الخاصة بك من سبتمبر وهجرة column "notification_level" of relation "user_chat_channel_memberships" already exists من أكتوبر، لذلك لم يتم تشغيلها على مثيلك السابق، وهي واحدة من أولى الهجرات التي تتم بعد الاستعادة.

يبدو لي هذا وكأن لديك مشكلة مختلفة. هل هذا تثبيت قياسي؟ وهل كان مثيلك السابق تثبيتًا قياسيًا؟ لدي شك في أن النسخة الاحتياطية لا يتم استعادتها بالمخطط الصحيح وأن الهجرات تعمل مقابل مثيل فارغ.

Dmitry_Krasnoperov · 10 يناير 2025، 3:53م

نعم، إنها تثبيت دوكر قياسي وتم إنشاء موقعي الأصلي باستخدام هذا الدليل في عام 2015.

هل هناك أي شيء يمكنني سحبه من بوستجريس أو كونسول ريلز لتسليط الضوء على ما يحدث؟

Dmitry_Krasnoperov · 11 يناير 2025، 2:38م

شكرا،
أي تلميحات أو نصائح أو توجيهات ستكون موضع تقدير كبير.

pfaffman · 11 يناير 2025، 7:23م

هل تقصد نسخة احتياطية من Discourse مقتصرة على SQL أم تفريغ SQL قمت بإنشائه بطريقة أخرى؟

Dmitry_Krasnoperov · 12 يناير 2025، 9:55ص

النسخ الاحتياطي لـ Discourse فقط.

في المنزل، قمت بإعداد PostgreSQL، وتمت استعادة النسخة الاحتياطية لبياناتنا تقريبًا دون أي مشاكل.
يبدو أنه عند استعادة الملف في PostgreSQL (الموجود داخل حاوية Discourse)، لا يتم حذف قاعدة البيانات القديمة، وهذا يسبب تعارضًا، مما يمنع نشر النسخة الاحتياطية بشكل صحيح.

pfaffman · 12 يناير 2025، 12:35م

يبدو هذا مثل ما كان يقوله ريتشارد.

كانت هناك بعض الالتزامات حول بوستجريس مؤخرًا، على الرغم من أنني لست متأكدًا من قبولها. قد تحاول إعادة البناء قبل محاولة الاستعادة مرة أخرى.

Dmitry_Krasnoperov · 12 يناير 2025، 1:54م

عند استعادة أرشيف sql.gz، يمكنني رؤية ما يلي:
…
نسخ الأرشيف إلى الدليل المؤقت…
استخراج ملف التفريغ…
التحقق من البيانات الوصفية…
الإصدار الحالي: 20241224191732
الإصدار المستعاد: 20240912212253

وبشكل واضح، تفشل عملية ترحيل قاعدة البيانات مع الخطأ المبلغ عنه في المنشور رقم 1.

يمكنني رؤية أن قاعدة بيانات postgres “discourse” تم استعادتها مع جميع الجداول/البيانات المطلوبة فيها:
psql (13.18 (Debian 13.18-1.pgdg120+1))
اكتب “help” للمساعدة.

لكن rake تبلغ عن استخدام قاعدة بيانات خاطئة:

rake db:version

database: discourse
Current version: 20241224191732

كيف يمكنني توجيه rake نحو 20240912212253؟

شكرًا.

RGJ · 13 يناير 2025، 5:00م

هذا ما يحدث عندما تكون هناك مشكلة في الأذونات. تتلاعب Discourse بالمخططات أثناء الاستعادة وعندما لا يكون لديها أذونات لسرد الجداول في قاعدة البيانات، تسوء الأمور.

على الرغم من أنني لم أواجه ذلك مطلقًا، فقد تكون هذه أيضًا مشكلة في مساحة القرص المتاحة؟

thoka · 13 يناير 2025، 5:10م

مجرد شعور داخلي: هل يمكن أن يكون هناك مهلة أثناء نقل الجداول بعد الاستعادة؟

Dmitry_Krasnoperov · 14 يناير 2025، 6:06ص

شكرا على التلميح.

مساحة القرص ليست مشكلة؛ لدي مساحة أكبر بـ 6-7 مرات من حجم قاعدة البيانات. يمكنني محاولة استيراد يدوي قبل تشغيل الترحيل وإصلاح الأذونات. السؤال هو، ما الذي يجب منحه بالضبط؟

Dmitry_Krasnoperov · 14 يناير 2025، 11:33ص

أعتقد أنك بحاجة إلى تحديث البرنامج النصي اليدوي بهذه الطريقة:

DROP SCHEMA public CASCADE;
CREATE SCHEMA public;
ALTER SCHEMA public OWNER TO discourse;
CREATE EXTENSION IF NOT EXISTS hstore;
CREATE EXTENSION IF NOT EXISTS pg_trgm;
END;

لا حاجة لإنشاء مخطط عام (وتعيين المالك)، لأن Pg الأحدث ينشئ مخططًا من تفريغ النسخ الاحتياطي لـ SQL.
ومع ذلك، يجب إصلاح أذونات الجدول للمستخدم discourse، افتراضيًا هي postgres.

الآن يعمل! شكراً لكم جميعاً على الأفكار والدعم.
