installation
1

Hello,

Due to a disk place problem, i cannot upgrade my installation since long time.
I’m curruntly using v2.0.0beta1…

I’ve 20gb on my VPS and i’ve 5.6gb free
I’ve alredy delete backups and lot of uploads…

When i try to upgrade, i’ve this:

WARNING: Docker version 17.05.0-ce deprecated, recommend upgrade to 17.06.2 or newer.

WARNING: We are about to start downloading the Discourse base image
This process may take anywhere between a few minutes to an hour, depending on your network speed

Please be patient

What can i do?

Ncdu tell me that:

Is it normal?

I don’t know how advisable it would be for a live site, but I have had this issue with one of my localhost intstalls I use for testing/development.

What works for me is skipping the prerequisites check i.e.
./launcher rebuild app --skip-prereqs

I Think there is a pending postgres update there. That will definitely need more disk space. Skipping prerequisites may result in a failed upgrade! isn’t it?

Good point. I haven’t updated that install since before the Postgres version upgrade so I may end up losing that one. Being a non-live forum the loss would be a disappointment, but losing a live forum would be much more of a problem.

Also, the docker version is outdated, That needs an upgrade first.

Thanks guys

Can i upgrade docker alone easily?

Yes, upgrade Docker first, there is no risk there and it should be done anyways.

The Postgres 10 upgrade does require enough disk space for a copy of the current database, so that’s the source of the issue.

Hello,

few days later, i’ve upgraded docker to the latest version, but the problem was the same.
I’ve solved the issue by changing my vps provider, ovh to digitalOcean. More space and lowest price :slight_smile:

Thanks
