ERROR: ENOSPC

JulioGurb

Hello!

I was changing the puredata patch of my bela mini. And this error appeared "Error: ENOSPC: no space left on device, write". Now it always appears when I try to upload a new patch.

However, it is absolutely not possible that there is not enough space, as there is nothing more inside the bela mini than the pd patch and a couple of pd external libraries. No audio files or anything heavy.

The first time this message appeared when I uploaded the new patch, the bela mini was receiving midi messages (sync and notes) from a drum machine via usb hub. All this midi messages were being printed in the console. Perhaps this messy situation made the bela mini get confused?

Thanks for the attention.

Best,
Julio

It may be that all the lines logged to the console have been filling up the logs. In principle there should be log rotation in place to avoid these becoming persistent on disk, but it's not the first time I see this fail.

To start off, try rm -rf /var/log and after that you should see a decent amount of free space with df -h /. (Run both commands in the IDE's console).

To prevent this from happening again, disable logging of midi messages by sending a [verbose 0( message to [send bela_setMidi].

Also once you are ready to turn this into an embedded instrument, follow the instructions here: https://learn.bela.io/using-bela/bela-techniques/deploying-the-board/

I did this and now I can succesfully upload the new patch. However, when I use the command "df -h /" it still say that I am using all the space and there is nothing more available. That doesn't look good, right?

Try rebooting and running df -h / again? If the deleted file is in use, it won't show the freed space until all programs that have it open let go of it. A reboot forces that.

If that is not enough, try running:

du -sh /root/Bela/projects/*

and

du -sh /var/*

and

du -sh /root/_BelaUpdateBackup

to identify the cause.

Btw, you are likely using an SD card that is larger than 4GB, so you can also use this to get much more space back, but unless you identify and fix the root cause of the space hogging, increasing the size will only temporarily hide the issue.
