Comment 3 for bug 1510511

Comment #1 specifies release, and package version (wily, release).

The disk space error I presume is of /var/lib/machines, which is managed by the systemd-machined entirely. It is a loop mounted btrfs file, which systemd should be automatically growing to correctly accommodate increases in the disk usage, which is clearly not working correctly here.

The current space reserved is:

$ sudo btrfs filesystem df /var/lib/machines
System, single: total=4.00MiB, used=4.00KiB
Data+Metadata, single: total=496.00MiB, used=32.00KiB
GlobalReserve, single: total=4.00MiB, used=0.00B
