It's more or less inherent to any COW style fs
What you can still do, however, is truncate an existing file. So find a
big file,
# cat /dev/null > /path/to/big/sacrificial/file
and repeat until you've freed up enough space to work more
conventionally. It gets more "entertaining" if snapshots are involved,
of course...
