August 1, 20223 yr I just experienced a very annoying issue: My cache drive is filled up, with docker btrfs subvolumes, from earlier Docker containers. I can't even install new Docker containers / reinstall them. Is there a way of knowing which is used and which not, so I can delete and use my cache again?

When I try it over the GUI, it freezes and when I try it over ssh or the normal syslog, I get the following error: Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 20480 bytes) in /usr/local/emhttp/plugins/dynamix/include/Syslog.php on line 18
August 1, 20223 yr Community Expert What do you get from command line with this? Before rebooting please df -h

August 1, 20223 yr Community Expert Is that before rebooting? I thought perhaps you had filled rootfs, but looks like cache is the only thing full.

Yes, this is what I wrote in my initial message: 1 hour ago, MagicLike said: My cache drive is filled up, with docker btrfs subvolumes, from earlier Docker containers.

I grabbed the diagnosis now, and from my perspective, nothing changed in my problem: How do I identify old - now unused - Docker btrfs subvolumes, so I can clear some space on my cache drive? By the way, the Docker container aren't starting anymore: Warning: stream_socket_client(): unable to connect to unix:///var/run/docker.sock (Connection refused) in /usr/local/emhttp/plugins/dynamix.docker.manager/include/DockerClient.php on line 710 Couldn't create socket: [111] Connection refused Warning: Invalid argument supplied for foreach() in /usr/local/emhttp/plugins/dynamix.docker.manager/include/DockerClient.php on line 896 diagnostics.zip
August 1, 20223 yr Community Expert Diags are incomplete, shares are missing, I wanted to see if there was something else on cache.

August 1, 20223 yr Community Expert Make sure disk shares are enabled, then click on cache and "compute" to see what exactly is using the space.

I just want to know, how i can identify, if they are used or not, so I can delete those unused...
