This diagnostic alert warns you when the free disk space for your local home or shared home directory falls below a set threshold.

The following appears in the application log:

ERROR ; OS ; OS-1002 ; Low free disk space ; not-detected ;  ;  ; {"directory":"...","freeInMegabytes":...,"totalInMegabytes":...,"minimumInMegabytes":...}

This alert is enabled by default in Confluence 6.11 or later.

### この問題の解決方法

To resolve this issue you'll need to provision more disk space.

### What will happen if I ignore this warning?

Once your disk is full, Confluence will be unable to write things like log files or scheduled backup files to disk.  End users will also see an error when attempting to upload files if the drive where attachments are stored has run out of space.

Can I change the threshold?

Yes, you can change the threshold of this alert using the following system property:

diagnostics.os.min.free.disk.space.megabytes
