I want to move my postgres
data folder to an NFS drive but I'm not sure what would be the best way to do it. I've got three options in mind:
According to Postgres Documentation, one method would be to use the
initdbcommand with the
initdbwill attempt to create the directory you specify if it does not already exist.
Another method listed on LinuxQuestions.org is to update the
postgressqlinit script to point to the new directory, which in this case would be the NFS drive.
Lastly, I was thinking I would just copy the
pgsql/datafolder to the NFS drive and simply symlink the folder.
pgsql/data -> nfs/data
Symlinking or updating the init script seem like the simplest approach to me, but I'm not sure if they would be best or the safest way. This is where I hope someone can help me out. Any suggestions, concerns, and pros/cons would be appreciated.
