As a first try you could export and reimport the pool. If it doesn't work: There is one problem with the current version in 8.x about space not freed (AFAIK in the ZIL). Just booting with a more recent version (9-current) and importing and exporting again should fix this issue (with 9-current there is also "zpool import -F <pool>" which is supposed to go back to a working state if a normal import is not possible, I suggest to search the net what it is doing exactly in case you need to use this). If you can not try this you could try to destroy this one FS on the pool and recreate it. Although, if you do not have (a place to make a) copy of this data, I do not know what to try else.
