ERROR: Extents overlap - URGENT

Hi! Executing command: $oncheck -ce produces the following result: ------------------------- Primary chunk /informix/dbspaces/pstntapdbs12, offset 0, size 680000 is down. Primary chunk /informix/dbspaces/pstntapdbs12, offset 0, size 680000 is down. ERROR: Extents overlap ERROR: Extents overlap ------------------------- First, how many errors are below? Two, four or one? There isn't any error number. In the Administrators Guide, there is written, that when I have "down chunk" which doesn't contains logical logs and ... "database server can continue to operate, but cannot write to or read from the down chunk or any other chunks in the dbspace of that chunk." But the situation is that I have a result for the query, which data are in this chunk. I found the tables in the chunk using "oncheck -pe". So, my "SELECT" returns me results without any errors, hence I can read from this chunk. In my "online.log" there isn't anything related that chunk is down, when I "oninit" Informix. Only "oninit" reports, that the chunk is down on the standard output when I initialize Informix. Is the only what I can do is to do a dbspace restore from the backup archive? The data in this dbspace aren't critical and doesn't depend from other data. Does my unloaded data are correct? (UNLOAD TO ... SELECT * FROM table_in_down_chunk) Thank you in advance! Best regards, Milen.
