Insufficient disk space

I couldn’t copy 1.5 GB of data into Nextcloud of my admin user with unlimited quota setting.
I have more than 100 GB of available space on the mounted data folder on my Raspberry.
First, I had 779 MB of free space according to the System menu of Administration settings, then I changed my user’s quota to be 5 GB.

This is what I get now in System:

Disk
You will get a notification once one of your disks is nearly full.
Files: 1140
Storages: 3
Free Space: -1891024896 B

I have docker, all mounted folders on the same physical drive (>100 GB free space), it is the same inside the container.

Thanks for any help!

What version of NC?

What Raspberry Pi?

If it’s a 4, have you upgraded it to a 64-bit OS or is still running a 32-bit variation?

I think you are on the right path.
NC is 26.0.1. Latest of the docker repo.
I have a RPi 4 and has the 64-bit kernel, but I think the user space is 32-bit only. Don’t really understand this part.
Some containers could pull and use the linux/arm64 platform images, e.g. photoprism or mariadb (arm64v8/mariadb), but nextcloud could only start up with linux/arm/v7 platform ones.

I include here some details:

I get the following error message…

x@host:~/docker $ docker compose up -d --build
image with reference nextcloud:latest was found but does not match the specified platform: wanted linux/arm64, actual: linux/arm/v7

…when I specify these lines in the docker-compose.yml file. changing to arm64 architecture:

    platform: linux/arm64
#    platform: linux/arm/v7

Which is strange, as arm64 works with everything else (mariadb, photoprism, portainer), except redis and nextcloud.

Redis only works with this config:

  redis:
    image: arm32v7/redis
#    image: redis:latest
    platform: linux/arm/v7
#    platform: linux/arm64

MariaDB works with the following:

  mariadb:
    image: arm64v8/mariadb:latest
    container_name: mariadb
    platform: linux/arm64

I also added this environmental variable:

x@host:~/docker $ export
declare -x DOCKER_DEFAULT_PLATFORM="linux/arm64"

There is a full 64-bit version of the Raspberry Pi OS. It sounds like maybe you upgraded the kernel to avoid having to reinstall?

I understand why: there’s no formal way to switch to the 64-bit edition without reinstalling. But then you end up with situations like this. :slight_smile:

That’s what I did finally. I installed Ubuntu arm64 on the Pi. It was a mess to configure the Postgres, so I finally went back to SQLite, then when I checked the System menu it show postgres being used. Interesting.
Anyways, works now. Thanks!
