Environment

SUSE Manager Server 4.2

Situation

The database migration  /usr/lib/susemanager/bin/pg-migrate-12-to-13.sh fails with below error message.
 

"Success. You can now start the database server using:

pg_ctl -D /var/lib/pgsql/data -l logfile start

15:03:58 Successfully initialized new postgresql 13 database.
15:03:58 Upgrade database to new version postgresql 13...

15:03:58 Trying to restore previous state...
mv: cannot move '/var/lib/pgsql/data' to '/var/lib/pgsql/data-new-failed/data': File exists"

Resolution

1) Workaround to fix the issue if encountered:

Find the original database within /var/lib/pgsql/data/ for example 
/var/lib/pgsql/data/data-pg12/data-pg12/data-pg12 or 
/var/lib/pgsql/data/data-pg12/data-pg12/ as per the entries created on the Server.
1) mv /var/lib/pgsql/data /var/lib/pgsql/data-backup
2) mv /var/lib/pgsql/data-backup/data-pg12/data-pg12/data-pg12 /var/lib/pgsql/data
3) mv /var/lib/pgsql/data-new-failed /var/lib/pgsql/data-new-failed.2

2)The fix to prevent the issue has been released through susemanager-4.2.21-3.3.1 and few other related packages.

Cause

This error is caused due to the failed database migration where /var/lib/pgsql/data contains data from previous failed migration which needs to be cleaned to fix the issue.
