Dropping a dbspace.

We are trying to drop a bad chunk. The chunk is a cooked file and is the only chunk in that dbspace. When I try to drop the chunk I get the following message. % onspaces -d ch_dbspace1WARNING: Dropping a DBspace/BLOBspace. Do you really want to continue? (y/n)y WARNING! The dbspace you wish to drop has been disabled. There may be database catalog entries for tables or indices which contain data in this dbspace. If you complete the drop they will be unusable. Do you really want to continue? (y/n)y Cannot drop the DBspace/BLOBspace. ISAM error: Primary and Mirror chunks are bad Does anyone know how to get rid of the chunk and dbspace catalog entries?
