Greg Roche · Answer

I m no expert but that error suggests to me that there s already something running on the system that s bound to port 5432 so prefect s postgres instance can t start

Greg Roche · Answer

you could either kill whatever is already running on port 5432 or start the server with `prefect server start postgres port x` where `x` is a port which isn t already being used on the machine

Thanks so I did that and killed the process and cleaned all docker containers and images

Newskooler · Answer

But then I got another error

Newskooler · Answer

`FATAL could not write lock file postmaster pid No space left on device` upon starting the server

Joël Luijmes · Answer

Well it says what is wrong doesn t sweat smile Your disk is full No kidding you probably should clean up your docker `docker system prune` check docs for everything it try to do or increase your docker volume in case of mac not sure how windows handles it

Newskooler · Answer

The thing is i do have plenty of GBs of space 200+ that s available hence my confusion

Joël Luijmes · Answer

Is that the disk of your machine or what docker has access to Because those are different things

Joël Luijmes · Answer

Kinda depends on your machiene OS and how you setup docker

Joël Luijmes · Answer

If it is macos for instance checkout the tips I gave either clean up your docker volume or increase it in size slightly smiling face

Newskooler · Answer

Ubuntu is what I am using The most recent error i saw is this `Error psycopg2 OperationalError could not translate host name postgres to address Name or service not known`

Newskooler · Answer

I did do `docker system prune` and reclaimed smile 17 more gigs so that was nice Thanks for that

Newskooler · Answer

I found the problem the location where Prefect saves data is full

Newskooler · Answer

How can I clean it up It s 100GB which is crazy considering I have used it for 20 days or so

Joël Luijmes · Answer

Woah that is alot no idea not running prefect in production yet But I could imagine if you use the LocalResult or some other Result mechanism it takes up space if that is the data you are referring to see if you can disable it or clean it up after a run

Newskooler · Answer

I don t know what s safe to delete This is not ` volume path` but instead it s the task `flow storage = Local directory= this location `

Newskooler · Answer

Do you recon it s save to clean up after evey task or once in a while

Joël Luijmes · Answer

Don t take my word for it but AFAIK the results is only used for caching Such that you can restart at a later point in the flow without having to recalculate earlier tasks Best to check docs to be sure slightly smiling face
