Hello,
He had a drive fail in an array and the spare kicked in to replace the
failed drive.  However, when I query a specific table, I get the below
error:

ERROR:  could not open file
"pg_tblspc/16412/PG_9.0_201008051/16419/5875980.7" (target block
2968776487): No such file or directory


When I change to this directory, the file in question does not exist.
Am I to assume that I'm completely hosed?  If the spare kicked in, what
happened to the file listed above?  Any hints would be most appreciated.

Thanks.

We were able to determine through a few of our queries that an index was
corrupt.  We did this through the process of elimination however.  As a
result, I have two questions:
How can I determine that we have a corrupt index?
How can I determine which datafile (5875980.x) is related to which
tablespace?

Yes, this can be achieved by block level checking with pg_dump utility::

pg_dump -d <DB Name> -p <Port> -v >/dev/null

If there is any corrupted indexes or tables  exists in the Database, it will
throw an error with block number.

Get oid & Name of the tablespace using below command:

select oid,* from pg_tablespace;

Once you get the oid,tablespace name, you can easily identify the which
datafile is related to which tablespace in "pg_tblspc" directory.
