Hello,
I was planning to upgrade from 12 to 13 using this command:
/usr/pgsql-13/bin/pg_upgrade -b /usr/pgsql-12/bin/ -B /usr/pgsql-13/bin/ -d /data/pg/ -D /pg/pgdata_13/ --jobs=10
And I got this output:
Checking for presence of required libraries ok
Checking database user is the install user ok
Checking for prepared transactions ok
Checking for new cluster tablespace directories
new cluster tablespace directory already exists: "/data/tsdb/metas/PG_13_202007201"
Failure, exiting
I think it's because /data/tsdb was my tablespace dir which was out of the old main data directory(/data/pg/).
So what should I do with old tablespaces when upgrading ?
Thanks a lot !
