Seems there's an 'orphan' volume which you can manually delete to make 
space. A while back there was an issue at some point where not all the 
volumes were deleted during a firmware update.

This seems to be the 'orphan' since there's not a corresponding 
'rofs-7e7e1530' volume, you can manually delete it with "ubirmvol 
/dev/ubi4 -n 1". You can also list all the volumes of a device with 
"ubinfo -a -d 0" for example.
