Off the wall idea #1:  

Drop the table. It was just a demonstration gimmick anyway, and can be recreated.  

Off the wall idea #2:  

You say it's the LOB index that's corrupt. Why not simply rebuild the index?  

Off the wall idea #3:  

Export the table with a pipe to gzip, which will cut down on the export's size by _at_90%.

I have an old 9i database with a table that appears to have been used as a test bed for as many oracle features as possible! In particular this table has  

a fine grained access control policy

a long raw column

a blob column  

The lob index is now corrupt. The recommended action is to export the table, drop the table and reimport - however the export file for this 12mb table grows to at least 2.4gb at which point disk space is exhausted.  

the date of corruption is unknown, so PIT recovery will be tricky of possible!  

alter table move lob... doesn't work because it also tries to rebuild the table segment which is not allowed because of the long raw.  

SQLPLUS copy doesn't work because of the 'object types' - presumably the BLOB.   I'm pretty much out of (cheap) ideas for dealing with this corruption right now, so would welcome some.
