Hi,
There was a disaster in my development note. I was able to recover the
data folder. PostgreSQL 9.6.2, was installed in Centos 7.
Here are the procedures I'm trying to initialize Postgresql for me to do
a backup.
1- I installed PostgreSQL 9.6.2 on a VM with Centos 7.
2- I stopped the PostgreSQL service: sudo systemctl stop postgresql-9.6
3- I renamed the /var/lib/pgsql/9.6/data folder to date data_old and
copied the old date folder
4- I gave permission in the folder date:
sudo chown postgres: postgres /var/lib/pgsql/9.6/data;
sudo chmod 700 /var/lib/pgsql/9.6/data
5 - I tried to start the service: sudo systemctl start postgresql-9.6
It is generating the following errors:
Abr 21 01:25:35 localhost.localdomain systemd[1]: Starting PostgreSQL
9.6 database server...

What do you see if you do the above, add -l to the systemctl command?

What does the system log show?

So you got a permissions error when the script was trying to read
PG_VERSION.
The suspicious part is this:
/var/lib/pgsql/9.6/data//PG_VERSION
in particular the //
Is that really the case?
Apr 21 04:01:48 localhost postgresql96-check-db-dir: An old version of
the database format was found.
Apr 21 04:01:48 localhost postgresql96-check-db-dir: You need to dump
and reload before using PostgreSQL 9.6.
Apr 21 04:01:48 localhost postgresql96-check-db-dir: See
/usr/share/doc/postgresql96/README.rpm-dist for more information.
Have to believe the above is a consequence of the permissions error. In
the event it is not:
1) What are the contents of PG_VERSION for data_old versus data?
2) Did you use the same repos in the VM that you used in the original
machine?
