Hi, Is phpBB3.3.3 supported or is it strictly 3.3.0? When performing the 1.5 step: /var/discourse/launcher enter import from Migrate a phpBB3 forum to Discourse - documentation / sysadmin - Discourse Meta I’m receiving (already tried twice) the response: x86_64 arch detected. Error response from daemon: No such container: import If I use /var/discourse/launcher enter import.yml the response is: x86_64 arch detected. ERROR: containers/import.yml.yml does not exist or is not readable. Available configs ( app, import ) Any chances this can work? Thanks

Hi, welcome! :wave: I assume you followed the guide from the start; is /var/discourse/containers/import.yml file actually present? It looks like the config file has been deleted. :thinking:

Yes, it’s like in the message above, both app.yml and import.yml are present in the “containers” directory.

If I understand well, you had no issue following the previous steps, creating/editing the import.yml next to app.yml, rebuilding the import container, and now you can’t even enter it. Is that right? That’s odd for sure! What returns this command? ls -l /var/discourse/containers

It’s still the same: app.yml and import.yml (plus a “bak” file of app.yml). There might be “issues” as I’ve been trying to install this on Lightsail 1GB (which is initially 940 and after updating Ubuntu becomes “921MB”). I used the official installation and what was installed was something like 3.3.* beta-something (while Wiki shows 3.2 as the most recent stable version). Installation takes 1h15min-1h20min with 4GB swap. the “launcher rebuild import” about 2h. Could something be incorrectly terminated due to the low memory condition? Btw, will backup files from the 2GB setup be readable in the 1GB setup?

[תמונה] JPD: “launcher rebuild import” about 2h Was it successful? After a rebuild, the container should be started. You can’t enter the container if it’s not started (./launcher start import) [תמונה] JPD: Could something be incorrectly terminated due to the low memory condition? That would likely be the case. There are several topics related to low memory/swap and rebuilding failure here – there is usually no choice but to increase RAM/swap. I’m not an expert here, but hopefully, someone can give you better insight.

Apparently, RAM is an issue. For the Lightsail 2GB/2GB, the clean installation is about 3.5-4x faster and the rebuilding of the import container was about (or even over) 10x faster. Still, I’m afraid the import script might not work for phpBB 3.3.3. Anyway, I tried twice with the same result: only one word from one category name (out of ~10 categories) was imported as one empty “category”. The MySQL textual dump is pretty small 2.66MB. All table prefixes are as required. No images, no smilies etc. All in all, no forums, no forum categories or posts, but all (a few hundred) users were imported correctly along with their statistics. It seems phpBB 3.3.3 was the update that changed something about the used MySQL version, but this is a dump file here, so it shouldn’t matter after all. Any ideas what else can be checked?

You mean 4GB to open/read/parse that 2.6MB text file? Are you the Discourse developer? A binary executable to read that dump (extracting all the data used by Discourse) and save it to anything else should be imo around 200KB with a, say, 100KB buffer (without bothering with the inclusion of the whole MariaDB for this simple action). I think it’s not about RAM. The procedure was fast and displayed importing progress for those imported tables. It didn’t “quit”. The users’ table is at the end of the dump, after the topics etc. I wanted to do this again, experimenting with copying/pasting that users table to the top and perform the same steps from the above manual/page (also with a dump created by phpMyAdmin instead of phpBB), but now Discourse refuses to start the procedure trying to connect remotely although no connection data was added. I rebuilt the import container, but perhaps something has to be deleted first?

I make my living supporting discourse and have done more migrations than I can count, but I think a hundred or more. 2gb will likely work, especially if you have only a few thousand topics and users, but since you need it for unit a small amount of time, more ram isn’t expensive and can’t hurt. I agree that it’s likely not the problem. When the script ran, did it count through the categories, users, topics, and posts? The script will skip over imported data, and creates custom field data to skip those in the future, so to run it again, you need to wipe the discourse database. Since you say it didn’t import anything it’s not clear whether that’s necessary. It would seem that either it did import it and you can’t find it for some reason, or it failed because it didn’t find the data, and you need to modify the script somehow; in neither of those cases should you need to wipe the database.

Since you say it didn’t import anything Not exactly: " all (a few hundred) users were imported correctly along with their statistics" I tried to rebuild the container again. The same settings. I didn’t change anything and after the step: import_phpbb3.sh # inside the Docker container the script now displays: /var/www/discourse/vendor/bundle/ruby/3.2.0/gems/mysql2-0.5.6/lib/mysql2/client.rb:97:in `connect’: Unknown database ‘phpbb’ (Mysql2::Error) Perhaps there are still some previously used temporary files to delete?

I would recommend at least 4gb of ram.

Are there any errors? It sounds like the script quit after it got one category?
