[root@DBSRV01 postgres10upd]#

where did i go wrong? why is it selecting that directory again and again? is is stored somewhere and being read from there thats why the same directory is always selected?

PS: a SAN is mounted to the opt directory using LVM. And i already have installed successfully on 2 other machines with same h/w & s/w configurations except that there is no SAN mounted to them.

Just now installed on another computer with the same configuration + SAN.. worked just fine [root@DBSRV02 postgres]# service postgresql-10 status pg_ctl: server is running (PID: 53224) /opt/postgres/10.5/bin/postgres "-D" "/opt/postgres/10.5/data".

Is it because the installation has once failed and that location is fixed ever since. can someone pls tell me how to remove the residues of the first failed installation.

Answer 1

Ok guys thank you all for the help! i found the culprit by searching for the directory using the command

grep -rlw "postgres10upd"

then i realized there is this file

/etc/postgres-reg.ini

with an entry

InstallationDirectory=/root/postgres10upd/y

I had edited it to "/opt/postgres/10.5"

then when installed there was no issues and got installed to exactly where i wanted.
