Help: FCP tells me (1) /var/log full and (2) unable to write to docker

[tknx]

Was trying to install some dockers and ran into errors.

 

Fix Common Problems shows the following:

 

The only new thing is I added a new drive to the array.

 

I looked through my logs and see a ton of bluetooth errors? No idea why or what is going on there. Diagnostics attached.

Go to the board BIOS and see if there's an option to disable the Bluetooth module.

[tknx]

Yeah - I will try that, but what is going on with that docker image?

Probably you have corrupted it by filling it. The fact that it is currently using 45G of the 100G allocated is further evidence that you have something wrong with one or more of your docker applications.

 

20G allocated is often more than enough. Maybe a little more depending on how many and which dockers. But not as much as you have.

 

The usual reason for an application to fill docker.img is writing to a path that isn't mapped to host storage.

[tknx]

Yep - I disabled bluetooth and it is fine.

 

Not that I am using bluetooth, but I would love to know how to fix this error since it feels like cheating

Post new diagnostics

[tknx]

So my docker image is quite large still, but diagnostics look cleaner.

Go to Docker, click Container Size button, and post the results

[tknx]

So, it says I have 40GB+ to scrub, but these sizes seem okay - maybe it is all good?

You could just delete, recreate as 30G, reinstall your containers from previous apps.

Why did you make it 100G to begin with?

[tknx]

I honestly don't remember why. Maybe I was facing a similar log issue in the past and just upsized to buy time?

 

Does it really matter though?

Increasing size of docker.img won't fix the problem of filling it, it will only make it take longer to fill. You should try to get to the bottom of why you fill docker.img with it only 30G as I recommended.

It is wasting space and possibly causing you to ignore problems with one or more of your container configurations.

 

The steps I linked in the wiki are simple. Did you read them?

[tknx]

Yeah - I will change it. I believe the last time I just upped it since I didn't have time to deal with the log issue and then fixed the log issue and didn't downsize. But I guess I'll reduce it back.

 

Thanks!
