Hi! Each time I launch /launcher rebuild app I get the following message (even if I launch it again) :
UPGRADE OF POSTGRES COMPLETE
Old 9.5 database is stored at /shared/postgres_data_old
To complete the upgrade, rebuild again using:
./launcher rebuild app
What information do you need to help me?
PS: The first time I ran it, the command stoped because I needed more space
Temporarily, I used the templates/postgres.9.5.template.yml template to avoid downtime. The app is running again, but I’d like to finish the update.
When I do a cleanup I get the following message : Old PostgreSQL backup data cluster detected taking up 1.2G detected. Would you like to remove it? (Y/n):
Sounds like a question for @tgxworld, but I am guessing that it failed due to lack of space but somehow didn’t catch that the upgrade had failed.
How much space do you have? And how big is your database?
Can you provide me with the full log generated during the rebuild? Thank you!
I’ve been having the same problem for many months now and I can’t upgrade my installation.
It loops and never succeeds. One problem during the rebuild app is this:
mv: cannot move '/shared/postgres_data' to '/shared/postgres_data_old': Device or resource busy
Entering in the Docker the postgres version I have is:
/usr/lib/postgresql/10/bin/postgres --version
postgres (PostgreSQL) 10.14 (Debian 10.14-1.pgdg100+1)
These are the errors I get:
FAILED
--------------------
Pups::ExecError: /root/upgrade_postgres failed with return #<Process::Status: pid 47 exit 1>
Location of failure: /pups/lib/pups/exec_command.rb:112:in `spawn'

** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages, there may be more than one.
./discourse-doctor may help diagnose the problem.
It looks like there’s a problem in the /pups/lib/pups/exec_command.rb script executing spawn.
I can start the app though
./laucher start app

What can I do?
Is your shared directory some sort of network mount?
No, but I’ve managed to do it finally!
The two mv commands in templates/postgres.template.yml are not checked for goodness. The script always says UPGRADE OF POSTGRES COMPLETE which is not true when the move is in error.
I removed the commands, then moved the directories by hand after entering in the docker, and the next rebuild app is currently working as before! I’m so happy 
Thank you.
PostgreSQL 13から15への最新のアップグレード中にこの問題が発生しました。
私たちのデプロイメントでは、/shared/postgres_dataディレクトリはより高速なNVMeストレージデバイスにマウントされているため、Device or resource busyというエラーメッセージが表示されて移動に失敗しました。
以下のようにpostgresテンプレートをパッチすることでこれを修正しました。
diff --git a/templates/postgres.template.yml b/templates/postgres.template.yml
