drive failure

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.
