I have my present database cluster of postgres at /mnt/my_hard_drive which I want to change to /home/myfolder. I also want to move all my databases present in the present cluster to /home/myfolder. Is there a way to do so?

I know one way for doing so is to dump my databases in some form e.g. .sql and reconstruct them from there. But considering my database size if 5TB I dont want to use this approach. Is there some other way to achieve this..since my machine is same...all I want to do is to move my database from hard drive to my home folder. Please suggest

  • You can just stop the DB, copy the cluster on FS level and start the DB with new cluster directory.

  • @IgorRomanchenko Thanks a lot for replying. I did stop postgres. But since I am a newbie with postgres I dont know as to how should I copy the database at the FS level. Also how should I start the DB with new cluster directory. For this do I have to create a new cluster. If yes, then how should I create one?

  • "copy at fs level" just means cp -r /old/cluster/path /new/cluster/path
