Re: systemd-journald[585]: Failed to create new system journal: Input/output error

[Neal Becker]

Finally got to the root problem.  It seems I'm running on btrfs (single 
device), and the metadata became too full.  This causes WIERD behavior - df 
would switch between sometimes showing 50% free space and 0% free.  
Operations would mysteriously fail with NOSPC even though there was loads of 
free space.

I got working again by deleting a bunch of files.  I think there is some 
other way I can get more metadata space for btrfs, but not sure about that.
